"For all that, you may be glad of my muscle when it comes to the point," was the answer.
At nine o'clock that night Quarles and I were concealed in the doctor's room, Quarles behind a chesterfield sofa in a corner, while I crouched close to the wall behind one of the window curtains.
We had decided that the most likely means of entry was by a window at the end of the hall, and we expected our prey to enter the room by the door. We had got the doctor to put a spirit tantalus on the sideboard, also some biscuits and a box of cigarettes. We were anxious to reproduce the circumstances of the burglary at Sir Joseph Maynard's as nearly as possible, for Quarles declared it was impossible to say what significance there might be in the man's every action.
So we waited—waited all night, in fact. Nothing happened.
"Something alarmed him," was all Quarles said when we left the house in the morning.
He showed no disappointment, nor any sign that his theory had received a shock.
The next night we were on the watch again, concealed as before.
By arrangement, the house retired to rest early. So slowly did time go that half the night seemed to have passed when I heard a neighboring church clock strike one, and almost directly afterward the door of the room was opened stealthily and was shut again.
Until that moment I had not heard a sound in the house, and I was not certain that anyone had entered the room even now, until I saw a tiny disk, the end of a ray of light, on the wall. The disk moved, so the man holding the lantern was moving. The next moment he almost trod upon me. His first care was to see that the curtains covered the windows securely, and it evidently never occurred to him that there might be watchers in the room. It was discovery from without that he was afraid of. The ray from his lantern swung about the room for a moment, then he switched on the electric light.
As he had drawn the curtain closer across the window, I had arranged the folds so that no scrap of my clothing should show beneath them. Now I made a slit in the fabric with my penknife so that I could watch him through it. He was middle-aged, well groomed, decently dressed. Having glanced round the room, he placed a bag and the lantern on the floor and went to the sideboard. He put a little spirit into one of the tumblers and added a little water—a very modest dose, indeed—and, having just sipped it, he poured some of the contents into two other glasses, and placed the three glasses on a small table near the door, so that no one could fail to see them on entering. Then he broke off a piece of biscuit, crumbled it in his hands, and scattered the crumbs beside the glasses. The cigarette box he did not touch, but he took some cigarette-ends from his pocket and threw them on the floor. These preliminaries seemed stereotyped ones, and he appeared glad to be done with them.
