<h2>CHAPTER XXX<br/> <span class="f8">THE SECRET PASSAGE</span></h2>
<p class="cap"><span class="upper">That</span> night was one of rest. I was physically tired
out, and after I had posted a few letters to merchants
in Aberdeen, giving orders for various
goods to be sent at once to Whinnyfold, I went to bed
and slept till the early morning. I got up at daylight, and
after my morning swim rode off to Crom. Again I
left my bicycle in the wood and took my way round to
the back of the hill and up through the wood to the
monument beyond the reservoir. It was still early morning,
as it is counted in the cities, though the sun was well
up. I went with extra caution, stealing from tree to
tree; for I knew nothing of the locality of the watchers
at this hour. I saw no sign of anyone; and coming at last
to where the rudimentary pathway lay, examined carefully
where I had placed the first thread. As I did so I
straightened myself quickly and looked round with apprehension.
The thread was broken across, though the two
ends were tied where I had placed them!</p>
<p>With a beating heart I examined all the others in turn,
with the same result. It was quite evident that some one,
or some thing had passed along the track. In spite of
my concern I rejoiced, for something had been found. It
was at least probable that there was a regular route
somewhere at hand. Accordingly I prepared my traps
afresh, this time placing them in various directions, and
at irregular distances along the path and all round the<span class="pagenum"><SPAN name="Page_245" id="Page_245">[245]</SPAN></span>
monument. I might thus be able to trace the exact route
of anyone who might disturb them. This done, and it
took some time, I went back to the wood, and thence
rode to the castle.</p>
<p>Marjory was eager for news, but it thrilled me to see
that her eagerness was not all from this cause; hour by
hour I found myself growing in her affection. When I
told her of the broken threads, she clapped her hands
with delight; the hunter spirit hereditary in her was
pleased. She gave her opinion that on the next morning
I should be able to locate the entrance to the passage, if
one there was. In the midst of her speaking thus she
stopped; a bright, keen light came into her eyes, and her
brows knitted.</p>
<p>“Why,” she said, “how stupid I am. I never once
thought of doing the same at my end. Yesterday, after
you left, I spent an hour in the old chapel and went over
every inch of it; but it never occurred to me to do there
what you had gone to do at the monument. If I had done
so, I might this morning have been able to discover the
secret of the disappearance of the kidnappers. I shall take
good care to do it this evening.”</p>
<p>While she was speaking a fear grew upon me lest
being alone in the ruin she might give her enemies the
very opportunity they wanted. She saw my distress, and
with her quick woman’s wit guessed the cause of it. With
a very tender movement she placed her hand on the back
of mine, and without squeezing it held it there firmly as
she said:</p>
<p>“Don’t be frightened for me, dear. These are expert
workmen that we are dealing with. They won’t move
till their plans are all ready. They don’t wish to get hold
of me for five minutes and let “Mac’s men”—as lacking
due respect for President McKinley, they call the Secret
Service agents of my country—catch them red-handed.<span class="pagenum"><SPAN name="Page_246" id="Page_246">[246]</SPAN></span>
They are only laying their plans as yet. Perhaps we may
have cause to be anxious when that is done; but as yet
it’s all right. Anyhow, my dear, as I know it will make
you easier in your mind, when you are not at hand to protect
me, I shall lay the traps whilst you are with me.
There now! Am I good to my husband, or am I not?”
I made her aware in my own way—I could not help it—that
she was good! and she let the incident pass unrebuked.
Even lovers, though they have not the status of
the husband, must be allowed a little latitude now and
again.</p>
<p>We talked over all the possibilities that we could either
of us think of with regard to a secret passage between
the castle and the monument. It was apparent that in
old time such a hidden way might have been of the utmost
importance; and it was more than possible that such a
passage might exist. Already we had reason to believe
that there was a way between the ruined chapel and the
top of the reservoir hill, and we knew that there must
be existing some secret hiding place gained from the
interior of the chapel. What we had still to discover, and
this was the most important of all, was whether there
was a method of communication between the castle and
the chapel. After tea we started out together; and as we
had arranged between us before starting, managed in our
strolling to go quite round the castle and through many of
the grassy alleys between the woods. Then, lest there
should be any listener, I said:</p>
<p>“Let us go into the old chapel. I haven’t had a good
look at it since I have been coming here!” So we went
into the chapel and began to lay our traps. Of course we
could not guard against any one spying upon us. There
might be eyes of enemies bent on us through some secret
chink or cranny or organised spy-hole. This we could not
help, and had to take our chances of it; but if anyone were<span class="pagenum"><SPAN name="Page_247" id="Page_247">[247]</SPAN></span>
within ear-shot and unable to see us, we guarded our
movements by our misleading remarks concerning history
and art. Deftly Marjory stretched sections of her
gossamer thread from place to place, so that if any one
went in the chapel their course must be marked by the
broken threads. We finished near the door, and our artless,
innocent, archæological conversation stopped there,
too. We strolled back to the castle, feeling sure that if
there were any secret hiding place within the ruin we
should have located the entrance to it in the morning.</p>
<p>That afternoon I went to the house at Whinnyfold.
Most of the things which I had ordered had arrived, and
when I had had the various boxes and bundles moved
inside I felt able to start on my work.</p>
<p>First I rigged up a proper windlass over the hole into
the cave; and fixed it so that any one could manipulate
it easily and safely from above. It could be also worked
from below by aid of an endless chain round the axle.
I hammered the edges of the hole somewhat smoother,
so that no chance friction might cut the rope; and I
fixed candles and lanterns in various places, so that all
the light which might be necessary could be had easily.
Then I furnished a room with rugs and pillows, and with
clothes for Marjory for changing. She would be sure to
require such, when our search after the treasure should
come off. I had ready some tins of provisions, and I had
arranged at the hotel that as I might sometimes stay and
work in my own home—I was supposed to be an author—some
fresh provisions were to be sent over each morning,
and left ready for me with Mrs. Hay at Whinnyfold. By
the time my work was through, it was late in the evening,
and I went to the hotel to sleep. I had arranged with
Marjory to be with her early in the morning. It was
hardly daylight when I woke, but I got up at once and
took my way towards Crom, for the experience of the<span class="pagenum"><SPAN name="Page_248" id="Page_248">[248]</SPAN></span>
day before had shown me that whoever used the path near
the monument used it in the grey of the dawn. As usual
I hid my bicycle and took my way cautiously to the
monument. By this time the sun was up and the day was
bright; the dew lay heavy, and when I came on any of
my threads I could easily distinguish them by the shimmering
beads which made each thread look like a miniature
rope of diamonds.</p>
<p>Again the strings across the path were broken. My
heart beat heavily as I began to follow back towards the
monument the track of the broken thread. It led right up
to it, on the side away from the castle, and then stopped.
The other threads all round the monument were intact.
Having learned so much, my first act was to prevent
discovery of my own plan. Accordingly I carefully removed
all the threads, broken and unbroken. Then I
began to make minute investigation of the monument
itself. As it was evident that whoever had broken the
threads had come straight from it, there was a presumption
that there was an opening somewhere. The rock
below was unbroken and the stonework was seemingly
fixed on the rock itself. By a process of exclusions I
came to the belief that possibly the monument itself might
be moveable.</p>
<p>Accordingly I began to experiment. I pressed against
it, this way and that. I tried to move it by exercising
pressure top and bottom in turn; but always without
avail. Then I began to try to move it sideways as though
it might be on a pivot. At first there was no yielding, no
answer of any kind to my effort; but suddenly I thought
I perceived a slight movement. I tried again and again,
using my strength in the same way; but with no result.
Then I tried turning it in the suspected direction, holding
both my hands low down on the corners of the
boulder; then going gradually up higher I pursued the<span class="pagenum"><SPAN name="Page_249" id="Page_249">[249]</SPAN></span>
same effort; again no response. Still I felt I was on the
track and began to make efforts in eccentric ways. All at
once, whilst I was pressing with my left hand low down
whilst I pulled with my right high up on the other edge,
the whole great stone began to move in a slow easy way, as
though in perfect poise. I continued the movement and
the stone turned lazily over on one side, revealing at my
very feet a dark opening of oval form some three feet
across its widest part. Somehow I was not altogether
surprised; my head kept cool in what was to me a wonderful
way. With an impulse which was based on safety,
lest the opening of the hole should make discovery of my
presence, I reversed the action; and the stone rolled slowly
over to its old position. Several times I moved it from
its place and then back again, so that I might become accustomed
to its use.</p>
<p>For a while I hesitated as to whether I should explore
the opening immediately; but soon came to the conclusion
that I had better begin at once. So I went back to my
bicycle and took the lamp with me. I had matches in my
case, and as I had the revolver which I always carried
now, I felt equal to any emergency. I think I was finally
influenced in my decision to attempt the passage at once
by the remembrance of Marjory’s remark that the kidnappers
would make no effort until their plans were quite
complete. They, more than I, might fear discovery; and
on this hope I was strong as I lowered myself down
through the narrow opening. I was glad to see that there
was no difficulty in moving the stone from the inside;
there were two iron handles let into the stone for the
purpose.</p>
<p>I cannot say I was at ease in my mind, I was, however,
determined to go on; and with a prayer to God for protection,
and a loving thought of Marjory, I went on my way.</p>
<p>The passage was doubtless of natural origin, for it was<span class="pagenum"><SPAN name="Page_250" id="Page_250">[250]</SPAN></span>
evident that the seams in the rock were much like those on
the coast where the strata of different geological formations
joined. Art had, however improved the place wonderfully.
Where the top had come too low it had been
quarried away; the remnants still lay adjacent where the
cave broadened out. The floor where the slope was steep
was cut into rough steps. Altogether, there were signs of
much labour in the making of the passage. As I went
down, I kept an eye on the compass whenever I came to a
turn, so that I might have a rough idea of the direction
in which I was going. In the main the road, with counterbalancing
curves and angles, led straight down.</p>
<p>When I had got to what I considered must be half way,
allowing for the astounding magnitude which seems to
be the characterisation of even a short way under ground;
the passage forked, and at a steep angle another passage,
lower and less altered than that along which I had come,
turned away to the left. Going a few feet up it I could
hear the sound of running water.</p>
<p>This was evidently the passage to the reservoir.</p>
