<h2> CHAPTER XX. An Act of Mademoiselle Stangerson </h2>
<p>"You remember me, Monsieur?" asked Rouletabille.</p>
<p>"Perfectly!" replied Arthur Rance. "I recognise you as the lad at the bar.
[The face of Rouletabille crimsoned at being called a "lad."] I want to
shake hands with you. You are a bright little fellow."</p>
<p>The American extended his hand and Rouletabille, relaxing his frown, shook
it and introduced Mr. Arthur Rance to me. He invited him to share our
meal.</p>
<p>"No thanks. I breakfasted with Monsieur Stangerson."</p>
<p>Arthur Rance spoke French perfectly,—almost without an accent.</p>
<p>"I did not expect to have the pleasure of seeing you again, Monsieur. I
thought you were to have left France the day after the reception at the
Elysee."</p>
<p>Rouletabille and I, outwardly indifferent, listened most intently for
every word the American would say.</p>
<p>The man's purplish red face, his heavy eyelids, the nervous twitchings,
all spoke of his addiction to drink. How came it that so sorry a specimen
of a man should be so intimate with Monsieur Stangerson?</p>
<p>Some days later, I learned from Frederic Larsan—who, like ourselves,
was surprised and mystified by his appearance and reception at the chateau—that
Mr. Rance had been an inebriate for only about fifteen years; that is to
say, since the professor and his daughter left Philadelphia. During the
time the Stangersons lived in America they were very intimate with Arthur
Rance, who was one of the most distinguished phrenologists of the new
world. Owing to new experiments, he had made enormous strides beyond the
science of Gall and Lavater. The friendliness with which he was received
at the Glandier may be explained by the fact that he had once rendered
Mademoiselle Stangerson a great service by stopping, at the peril of his
own life, the runaway horses of her carriage. The immediate result of that
could, however, have been no more than a mere friendly association with
the Stangersons; certainly, not a love affair.</p>
<p>Frederic Larsan did not tell me where he had picked up this information;
but he appeared to be quite sure of what he said.</p>
<p>Had we known these facts at the time Arthur Rance met us at the Donjon
Inn, his presence at the chateau might not have puzzled us, but they could
not have failed to increase our interest in the man himself. The American
must have been at least forty-five years old. He spoke in a perfectly
natural tone in reply to Rouletabille's question.</p>
<p>"I put off my return to America when I heard of the attack on Mademoiselle
Stangerson. I wanted to be certain the lady had not been killed, and I
shall not go away until she is perfectly recovered."</p>
<p>Arthur Rance then took the lead in talk, paying no heed to some of
Rouletabille's questions. He gave us, without our inviting him, his
personal views on the subject of the tragedy,—views which, as well
as I could make out, were not far from those held by Frederic Larzan. The
American also thought that Robert Darzac had something to do with the
matter. He did not mention him by name, but there was no room to doubt
whom he meant. He told us he was aware of the efforts young Rouletabille
was making to unravel the tangled skein of The Yellow Room mystery. He
explained that Monsieur Stangerson had related to him all that had taken
place in the inexplicable gallery. He several times expressed his regret
at Monsieur Darzac's absence from the chateau on all these occasions, and
thought that Monsieur Darzac had done cleverly in allying himself with
Monsieur Joseph Rouletabille, who could not fail, sooner or later, to
discover the murderer. He spoke the last sentence with unconcealed irony.
Then he rose, bowed to us, and left the inn.</p>
<p>Rouletabille watched him through the window.</p>
<p>"An odd fish, that!" he said.</p>
<p>"Do you think he'll pass the night at the Glandier?" I asked.</p>
<p>To my amazement the young reporter answered that it was a matter of entire
indifference to him whether he did or not.</p>
<p>As to how we spent our time during the afternoon, all I need say is that
Rouletabille led me to the grotto of Sainte-Genevieve, and, all the time,
talked of every subject but the one in which we were most interested.
Towards evening I was surprised to find Rouletabille making none of the
preparations I had expected him to make. I spoke to him about it when
night had come on, and we were once more in his room. He replied that all
his arrangements had already been made, and this time the murderer would
not get away from him.</p>
<p>I expressed some doubt on this, reminding him of his disappearance in the
gallery, and suggested that the same phenomenon might occur again. He
answered that he hoped it would. He desired nothing more. I did not
insist, knowing by experience how useless that would have been. He told me
that, with the help of the concierges, the chateau had since early dawn
been watched in such a way that nobody could approach it without his
knowing it, and that he had no concern for those who might have left it
and remained without.</p>
<p>It was then six o'clock by his watch. Rising, he made a sign to me to
follow him, and, without in the least tying to conceal his movements or
the sound of his footsteps, he led me through the gallery. We reached the
'right' gallery and came to the landing-place which we crossed. We then
continued our way in the gallery of the left wing, passing Professor
Stangerson's apartment.</p>
<p>At the far end of the gallery, before coming to the donjon, is the room
occupied by Arthur Rance. We knew that, because we had seen him at the
window looking on to the court. The door of the room opens on to the end
of the gallery, exactly facing the east window, at the extremity of the
'right' gallery, where Rouletabille had placed Daddy Jacques, and commands
an uninterrupted view of the gallery from end to end of the chateau.</p>
<p>"That 'off-turning' gallery," said Rouletabille, "I reserve for myself;
when I tell you you'll come and take your place here."</p>
<p>And he made me enter a little dark, triangular closet built in a bend of
the wall, to the left of the door of Arthur Rance's room. From this recess
I could see all that occurred in the gallery as well as if I had been
standing in front of Arthur Rance's door, and I could watch that door,
too. The door of the closet, which was to be my place of observation, was
fitted with panels of transparent glass. In the gallery, where all the
lamps had been lit, it was quite light. In the closet, however, it was
quite dark. It was a splendid place from which to observe and remain
unobserved.</p>
<p>I was soon to play the part of a spy—a common policeman. I wonder
what my leader at the bar would have said had he known! I was not
altogether pleased with my duties, but I could not refuse Rouletabille the
assistance he had begged me to give him. I took care not to make him see
that I in the least objected, and for several reasons. I wanted to oblige
him; I did not wish him to think me a coward; I was filled with curiosity;
and it was too late for me to draw back, even had I determined to do so.
That I had not had these scruples sooner was because my curiosity had
quite got the better of me. I might also urge that I was helping to save
the life of a woman, and even a lawyer may do that conscientiously.</p>
<p>We returned along the gallery. On reaching the door of Mademoiselle
Stangerson's apartment, it opened from a push given by the steward who was
waiting at the dinner-table. (Monsieur Stangerson had, for the last three
days, dined with his daughter in the drawing-room on the first floor.) As
the door remained open, we distinctly saw Mademoiselle Stangerson, taking
advantage of the steward's absence, and while her father was stooping to
pick up something he had let fall, pour the contents of a phial into
Monsieur Stangerson's glass.</p>
