<h2>CHAPTER XI</h2>
<p>As the horses started up, Dorothy refuted Tom’s
statement indignantly. “It isn’t a blind alley. It’s
a good clue. We’ve run down practically every
other line, and now we may as well try this. Everything
points to the belief that ‘the man’ is a
scientist of no slight ability. Whether he or some
one else discovered his high power radio-active
force, he must be a good man, or he wouldn’t be
able to use it. Now, it seems probable to me that
he was working with phosphorescent ink simply
because it was the nearest at hand. A man engaged
in research like that would be likely to have
at least one assistant. I propose to find that
assistant.”</p>
<p>“I’d like to see you do it,” said Tom doubtingly.
“How would you go to work?”</p>
<p>“I’d advertise,” said Dorothy.</p>
<p>“Advertise,” remarked Tom. “Here’s the way
to do it,—‘Wanted, the assistant of the man who
is trying to stop all war.’”</p>
<p>“Of course not, stupid,” said Dorothy impatiently.
“We’ll advertise for a man who has had
some experience in making phosphorescent ink.<span class="pagenum"><SPAN name="Page_143">[143]</SPAN></span>
That’s the line to work on. Don’t you see that
since phosphorescent paint acts best with such
energy as is given by radio-active substances, that
he’s likely to have been using it. There’s such a
close relation between phosphorescence and radioactivity,
that a man might be working with both.”</p>
<p>“But where will you advertise?” I said. “How
can you tell where the man has worked? How
can you tell his nationality? I think he is an
American, but no one can tell.”</p>
<p>“If you mean Dick Regnier,” exclaimed Dorothy,
her eyes flashing, “you’re wrong. I’ve known
him for years, and I know he is not the man. It
takes just a touch of insanity that Dick never had,
to do what ‘the man’ is doing. ‘The man’ must
be practically a monomaniac on the subject.”</p>
<p>The bus stopped just as the Bank came in sight.
Dorothy turned squarely in her seat and faced me.
The seats around us happened to be empty. She
looked at my somewhat guilty face and spoke
emphatically.</p>
<p>“Jim Orrington, you don’t believe me, but it
isn’t Dick Regnier.”</p>
<p>“Now, Dorothy,” I said, “look here. How did
the letter get changed, unless it was done by
Regnier that night at your cousin’s?”</p>
<p>“I don’t know,” she answered.</p>
<p>“Oh, come now,” said Tom. “Drop it. Here’s
where we get off.”</p>
<p><span class="pagenum"><SPAN name="Page_144">[144]</SPAN></span></p>
<p>We had drawn our money and had started away,
when I suddenly thought of the mail. I turned
back to the little window and asked if there were
any letters for us which had not been forwarded.
A few moments brought a big package, among
them three or four bulky envelopes from the office.
Hailing a cab, we read busily as we drove back to
the Savoy. One long typewritten report I read
with especial care, and handed over to Dorothy
when she had finished her mail. She looked at
me reproachfully, as she read the title. “And you
never mentioned this at all.”</p>
<p>“I forgot all about it,” I answered. “I started
that inquiry the day I was in prison. The night I
got out, the Denckel letter came, and we’ve been
so busy ever since that I completely forgot this.”</p>
<p>“Let’s hear it,” said Tom.</p>
<p>“Just read the condensed paragraph at the top,”
I said. “That tells the whole story. You can
read the rest at your leisure.” Dorothy began
in her clear voice.</p>
<p>“Report on Mr. Richard Regnier. Richard
Regnier is the son of the late Colonel Arthur
Regnier of Savannah, Georgia. He was educated
at private schools, and at Princeton. His residence
is Savannah, but he has spent much time in England.
He specialized in chemistry when in college,
and published one paper after graduation on some
rare chemical compounds. He has no regular<span class="pagenum"><SPAN name="Page_145">[145]</SPAN></span>
occupation, has an independent income, and spends
most of his time in various philanthropic works. Is
a member of several organizations, such as the
Peace Society, the Tuberculosis League, etc., and
of four clubs. Complete details given below.
Every effort has been made to obtain his present
address, but not even his bankers know it. The
only fact concerning this which could be obtained
was that he sailed for Europe on the Hamburg-American
line, the last of June, this present year.
For details of this part of the investigation, see
below.”</p>
<p>“Well, he didn’t do it; he isn’t doing it,” said
Dorothy emphatically.</p>
<p>“He’s got the training for it,” said Tom reflectively.</p>
<p>“I am sure,” began Dorothy, but I broke in.</p>
<p>“What’s the use of discussing it now. We can’t
get hold of Regnier, anyway, and your phosphorescent
ink scheme seems the next scheme to
try. Here we are at the Temple. Let’s go to one
of my friends who is a solicitor here, and see if we
can use his office as headquarters to see the applicants.”
So the discussion ended.</p>
<p>A brief interview with my friend, and a short
debate on the best method of procedure, brought us
to certain conclusions. It was really just as possible
that the man had worked in London as anywhere
else, and we decided to advertise in six of<span class="pagenum"><SPAN name="Page_146">[146]</SPAN></span>
the morning papers for three days, asking for a
man who had had some experience with phosphorescent
inks, and who was capable of assisting
in a scientific examination with regard to them.
Applicants were to meet at the office of my friend
in the Middle Temple at three o’clock on the afternoon
of the third day.</p>
<p>For two days and a half I spent my time watching
the preparations for war, and urging forward
the search for Regnier. He had completely
dropped out of sight. No information of his
whereabouts could be obtained, and when we met
at the Temple on the afternoon of the third day,
we were no further ahead.</p>
<p>At three o’clock the waiting room of the office
was full, and a long line of men extended down
the stairs. The crowd bore striking witness to the
horde of unemployed seeking for even the slightest
chance of employment. My friend’s clerks were in
despair, but somehow they managed to evolve
something like order from the mass, and one by
one the applicants were admitted. After the first
half dozen, we saw that they could be divided into
three classes,—the men who knew nothing about
science and nothing about any kind of ink, the men
who knew something about ink but nothing about
phosphorescent ink, and the men who had been
laboratory assistants to various research followers.
We divided them rapidly on this basis, and in an<span class="pagenum"><SPAN name="Page_147">[147]</SPAN></span>
hour had dismissed all the members of classes one
and two. There were left some ten others who had
been assistants in research laboratories. One by
one we examined these. They had worked in
various lines; the first five in chemical researches;
the last five in various physical and engineering
lines. Try as we might, we could get no information
from any of them with regard to phosphorescent
ink, or with regard to any unusual work with
radio-active energy.</p>
<p>The last man had been dismissed and we had sat
down to afternoon tea with my friend, when we
heard words in the outer office. The door opened
and a clerk entered. “There’s one man more,
sir,” he said, “I told him he was too late, but he’s
quite insistent, sir. Will you care to see him?”</p>
<p>“Surely,” I said, and we all went out into the
outer office. A tall, bent man with drooping
mustache stood by the window. His gaunt face
and threadbare clothes, neatly brushed though
they were, showed an evident lack of prosperity.</p>
<p>“I ventured to insist, sir,” he said, addressing
me, “as I have had quite a little experience in
phosphorescent ink. It was only a year ago that I
served in a laboratory where they were working
with it, and while I was simply working under the
direction of other people, I think I could work well
along that line. I should try to do my best. I need
a place.”</p>
<p><span class="pagenum"><SPAN name="Page_148">[148]</SPAN></span></p>
<p>This looked more like the real thing. I waved
towards Tom. He could run this end of the inquiry
better than I.</p>
<p>“What’s your name?”</p>
<p>“George Swenton.”</p>
<p>“Where did you have your experience?” questioned
Tom.</p>
<p>“With Doctor Heidenmuller, in his private
research laboratory,” answered the man.</p>
<p>“What training have you had?”</p>
<p>“Not much. Only a few courses at the University
of London. I was only the second assistant.
I worked with Doctor Heidenmuller for four years,
until he died six months ago. I have had no place
since, sir.”</p>
<p>“Did your employer do anything with radio-active
work?”</p>
<p>“Yes, sir. He died that way. He was killed,
paralysed, you might say, while working with
something in a locked room. He always did that
work in a locked room.”</p>
<p>“What were the circumstances of his death?”
asked Tom. The man hesitated and looked up
somewhat fearfully.</p>
<p>“I don’t see what that has to do with phosphorescent
ink,” he said. “The police went all
into the matter of his death, and they said it was
just death by paralysis.” He stopped and shut
his mouth hard. Dorothy broke in.</p>
<p><span class="pagenum"><SPAN name="Page_149">[149]</SPAN></span></p>
<p>“Mr. Swenton, here is the state of affairs. I
don’t think my brother has made it quite plain.
We are more interested in Dr. Heidenmuller’s
radio-active work than in his phosphorescent paint.
We have no question of you at all. We do not want
to know anything which is not entirely right for us
to know, but we do want to know all you feel you
can rightly tell us of his work. I feel sure that my
brother will be ready to employ you, if you can
show that you have done this, and that you can do
what he wants.”</p>
<p>The man’s face cleared. Dorothy’s words were
more convincing than evidence. He reached into his
pockets and drew forth a bunch of papers, which
he gave to Tom, who rapidly ran through them.</p>
<p>“They’re all right,” he said, handing them back.
“Now, if I give you twenty pounds a month for two
months, will that be all right?”</p>
<p>A dull red rose in the man’s face as his eyes
lighted. “It will mean everything to me, sir,” he
said. “I’ve got a wife and a boy.”</p>
<p>Tom drew out his purse. “Here’s ten pounds
to clinch the bargain,” and he handed him two
five pound notes.</p>
<p>“I appreciate that more than I can say,” said
the man, the tears welling up into his eyes with
emotion. “Now, what did you want to know?”</p>
<p>“First about Dr. Heidenmuller’s apparatus,
and then about his death.”</p>
<p><span class="pagenum"><SPAN name="Page_150">[150]</SPAN></span></p>
<p>“I’m afraid I can’t tell you much of the apparatus.
I never even saw it. It was in an inner room
to which the doctor had the only key. I never was
in the room till the day we broke down the door
and took him out dead. There was no apparatus
there then. It must have been removed.”</p>
<p>“How did the room look?” asked Dorothy.</p>
<p>“It was all bare. Nothing in it at all, except the
wooden chair where he sat and a wooden table.”</p>
<p>“How about the walls and ceiling?”</p>
<p>“They were all of wood.”</p>
<p>“How about the locks on the door and windows?”</p>
<p>“That was a funny thing. They were of wood,
too, though he had an iron key.”</p>
<p>“What did the doctor have in his pockets?”</p>
<p>“Four five-pound notes, no change, and his
watch was gone. There was nothing in his watch
pocket except a watch crystal. His keys were gone,
too, and only the ribbon of his watch was left lying
on the floor.”</p>
<p>“What did the doctors say about his death?”</p>
<p>“Straight paralysis, they said. I had been
away for three days. He was around the laboratory
for one day after I left, and the day after that
he must have died. They said death was instantaneous.”</p>
<p>“Did the doctor leave any family?”</p>
<p>“None.”</p>
<p><span class="pagenum"><SPAN name="Page_151">[151]</SPAN></span></p>
<p>“What became of his papers?”</p>
<p>“Nobody knows. He had scarcely any friends.
His property went to a niece in Germany, and she
came over to hunt for papers, but she found none.”</p>
<p>“What became of the other assistant?”</p>
<p>“He went back to Germany. He knew nothing
more than I did, however.”</p>
<p>“Did the doctor have any friends who came to
see him?”</p>
<p>“Very few. There was one American who came
to see him now and then. I never knew his name
or where he came from, nor did I know the name
of the two or three German friends he had.”</p>
<p>“Anything else you think of?” asked Tom.</p>
<p>“Nothing else, I’m afraid,” answered Swenton.</p>
<p>Tom rose from his chair and paced up and down
the room, his hands in his trousers pockets, his
coat flung back. As he walked, Swenton, watching
him, uttered an exclamation.</p>
<p>“I can tell you one thing about the American,”
he said. “He wore a peculiar shaped pin on his
waistcoat, such as you wear on your fob.”</p>
<p>Tom pulled up his fob with its Theta Sigma
Rho pin. “There’s a good clue, anyway,” he said.
“He must be a Theta Sigma Rho man.”</p>
<p>We could get nothing more from Swenton and,
after directing him to call at the Savoy the next
morning, we sent him away happy. As we came
down the narrow stairs and out of the old arched<span class="pagenum"><SPAN name="Page_152">[152]</SPAN></span>
passages of the Temple, Dorothy said, “Let’s
walk up the embankment to the hotel. We can
think better that way.”</p>
<p>We had gone half the distance, when she
stopped. “Suppose we talk it over here,” and we
stopped beside the parapet to discuss the matter.</p>
<p>“As I make it out,” said Tom, “Heidenmuller
was the man who discovered the secret power
which has been destroying the battleships, but he
can’t be ‘the man,’ because he died before the
first ship went down. Therefore he must have
passed it on to some one else who is using it,
possibly the American who was his friend, or one
of the Germans. It strikes me that the next thing
to do is to find an American in London who wears
a Theta Sigma Rho pin.”</p>
<p>Instantly I startled the peaceful calm of the embankment,
and made myself an object of suspicion
to the neighboring bobby, by leaping in the air and
clapping my hands together.</p>
<p>“Hamerly, by all that’s holy!” I cried. “You
remember that fellow I took home that night you
arrived, Dorothy?”</p>
<p>She nodded, her eyes gleaming with interest.</p>
<p>“He’s one of our men, and he had an acid stain
on his coat. I’ll wager you he’s the American. I
know where he lives and I’ve been up to see him
once, but he was out. I’ll go up there right after
dinner.”</p>
<p><span class="pagenum"><SPAN name="Page_153">[153]</SPAN></span></p>
<p>“Do you think he’s ‘the man’?” asked Tom
in excitement.</p>
<p>“I don’t see how he could be,” I said slowly.
“‘The man’ was working in the Channel, when
he was in the British Museum. But he’s surely
the next man to interview.”</p>
<p>By eight I was in a hansom speeding towards
Half-Moon Street. “Was Mr. Hamerly in?”
He was, and met me half way down the stairs.
“This is very good of you, Orrington,” he said.
“I was very sorry to miss your last call.”</p>
<p>For some time we talked of various things, of
college days, and of affairs at home. He had come
over as a Rhodes scholar and, having a little money
left him while at Oxford, had gone on in London
after graduation, leading a life of quiet study. As
we talked, I sized my companion up. “A trifle
grave but, after all, a sane, sterling fellow,” I
decided, and I put my errand directly to him.</p>
<p>“You knew Dr. Heidenmuller,” I said abruptly.</p>
<p>“Yes, poor old chap,” he said calmly. “How
did you happen to run across him?”</p>
<p>“I didn’t know him personally,” I said, “but
I knew a man who did know him. One of our
own men, Tom Haldane of Columbia, who is very
greatly interested in the radio-active work which
Dr. Heidenmuller was carrying on before his
death, is here with me.”</p>
<p>Hamerly’s face filled with eagerness. His whole<span class="pagenum"><SPAN name="Page_154">[154]</SPAN></span>
attitude changed. “Did Haldane know what he
was doing?” he asked breathlessly.</p>
<p>“Not exactly,” I said.</p>
<p>“Well if he knows anything about it, I believe
he knows one of the greatest things in modern
science. The Doctor never told me anything about
it, but I went into that room the day he was taken
out dead, and ever since that time I’ve felt that he
had found a force greater than anything yet obtained,
and that that force killed him.” He
paused. “I’ve never said that to anybody else,
but Haldane is the man of all others to know it,
and you might tell him that from me. He may be
able to use it somehow. I can’t. I tried my best
to get hold of some clue concerning it after Heidenmuller’s
death, but it was absolutely useless. Do
you think that Haldane has enough data to work it
out?”</p>
<p>“Frankly, I don’t know,” I said.</p>
<p>“Except for two things, I should have said the
secret died with him,” said Hamerly slowly.</p>
<p>I bent forward hanging on every word.</p>
<p>“I’ve never spoken of either, but,”—he paused,
“you know this man who is trying to stop all war?”</p>
<p>I nodded.</p>
<p>“Well, from the way Heidenmuller’s room
looked, and the way the things in his pockets were
left, I’ve wondered if the man had not his secrets.
Do you know,” he said, leaning forward, “there<span class="pagenum"><SPAN name="Page_155">[155]</SPAN></span>
were no eyelets in his shoes when he was found.
The crimps were in the leather of the strings, but
the metal ends were gone. The lenses of his spectacles,
without any mounting, were lying on the
floor. The very filling of his teeth had gone. Why
couldn’t a battleship disappear into its elemental
parts the same way, all its living contents paralyzed
by the shock, dying instantly and sinking below
the waves. I’ve wondered more than once if the
government sent down divers in Portsmouth harbor
and if they did, what they found.”</p>
<p>There was just one thing to do. He held as
much as we did of the secret. Perhaps he knew
more. From beginning to end, I told the whole
story of our search. As I went on, he grew more
and more excited. As I paused towards the end,
he broke in.</p>
<p>“The second thing fits in here, the reason why
I believe the secret might not be lost. One day
as I went into the laboratory, the Doctor’s assistant
told me that he was in the inner room,
but had left word for me to wait. I was extremely
curious for no one had ever entered that inner room
to my knowledge. The door opened at last, and a
tall, dark man, an American I should say, came out
of that closed room with the doctor. I never saw
him before or since. Now, is he the man who got
the secret, and with it is trying to stop all war?”</p>
<p>I was out of my seat with excitement. “I believe<span class="pagenum"><SPAN name="Page_156">[156]</SPAN></span>
he is. Would you know him if you saw his
photograph?”</p>
<p>“Surely,” said Hamerly.</p>
<p>I rose to go.</p>
<p>“Hold on,” exclaimed Hamerly, “I haven’t
told you half yet.”</p>
<p>“Go on,” I said eagerly, seating myself once
more.</p>
<p>“That first day, after I had made a rough examination,
I started to go over the inner room inch by
inch. At first I thought it was perfectly insulated
by wood. There wasn’t a piece of metal nor even a
piece of glass in it. Where the incandescent light
came down, hung a bit of twisted cord, without a
scrap of metal remaining. There was a length of
insulating cloth, minus the wire it covered, lying
on the floor. I went round and round, hunting
for metal, but I could find none. There was a
wooden shutter over the window, and no glass. I
closed the door and walked over every inch of the
room, trying to find any break whatsoever in the
insulation. The only thing I could find was a
faint glimmer, where the wooden window shutter
did not quite join. I went outside and studied
the place from the street. There was no appearance
of anything unusual on the wall of
the laboratory, excepting that the boarded window
of the wooden room looked out like a rectangular
unseeing eye. I crossed to the sidewalk<span class="pagenum"><SPAN name="Page_157">[157]</SPAN></span>
just before the laboratory, and looked up and
down the opposite wall. There was nothing unusual
on that side, save two square places, side
by side on the painted wall, which looked fresher
than the wall around. I examined them more
carefully, crossed and recrossed. The two spots
were almost exactly opposite the lower end of the
shuttered window where I had seen a slight chink
of light, the only place where the insulation of wood
was broken. I went up the stairs of the house
opposite. It was a little tea shop. A wooden sign
leaned against the wall beside the door. I picked it
up. The screw holes and the whiter paint where
the hinges had lain showed clear, but there was no
metal about it. The proprietress bustled up to
take my order and, as she saw me looking at the
sign, broke into voluble explanation. ‘I should
have put the sign back in its place, sir, but fairly
didn’t dare to. It was a week come Tuesday when
it fell. It’s God’s own mercy there wasn’t somebody
killed, sir. And the strangest thing, too. I
couldn’t find sight nor smell of the hinges and the
rod where it hung. It must have pulled out of the
wall, and somebody have picked up the iron, before
I could get down, sir. Now isn’t that strange,
sir?’</p>
<p>“It had fallen the day that Heidenmuller died.</p>
<p>“I went back into the laboratory and hunted
over every square inch of it, but I found nothing.<span class="pagenum"><SPAN name="Page_158">[158]</SPAN></span>
I stood there puzzling. If there had been some
power that had killed Heidenmuller, there must
have been some material substance in which it was
kept. I had made the most careful inquiries about
the things on his person and in the room. No one
could tell me anything. Swenton and Griegen, the
two assistants, were neither of them there, but the
first one who had entered the room when the
doctor’s body was found was a sharp-faced lad
who acted as janitor. I had questioned him
thoroughly, as I thought, but I resolved to see if
he did not know more. I went to him again, and a
lucky inspiration came to me. Holding a sovereign
in my hand I remarked casually, ‘If there is any
little personal memento of the doctor left, I should
like very much to have it.’ The narrow eyes of the
lad gleamed. He thrust his hand into his pocket,
and drew out what was apparently a leather
cigarette case, snatched the sovereign, and handed
me the case. ‘Found h’it h’on the floor, h’after
we took ’im h’out,’ he mumbled. ‘H’it’s the h’only
think was there.’”</p>
<p>Hamerly rose as he spoke and walked to his desk.
I followed, my heart pulsating with great leaps.
He took from a drawer what seemed to be a pigskin
cigarette case, cut in half. Hamerly held the
two sections out on his hand. At the top was a
queerly constructed valve,—the case was lined
with a black substance that looked like rubber.</p>
<p><span class="pagenum"><SPAN name="Page_159">[159]</SPAN></span></p>
<p>“I believe,” said Hamerly gravely, “that in this
case there was some terrifically powerful substance,
which killed Heidenmuller and destroyed all the
metal in the wooden room, by escaping through
the accidentally opened valve. I believe the man
who is trying to stop all war uses the same dread
agent. I believe, once the substance escapes and
does its work, that it turns to a harmless gas, as
hydrogen, once it has been exploded with oxygen,
forms harmless water, or as the carbon of coal,
which has blazed when united with the oxygen of
the air becomes, after that union, inert carbon
dioxide. You know, now, all I know. I’ve done
all I could with it,” he ended, “Take it to Haldane.”</p>
<p>Dazed with the story, I could only thank him
and take the case. We parted with a word of good
will, and assurance of secrecy on his side.</p>
