Having guarded against the possibility of this disaster, I proceeded to make myself comfortable for the evening. Tired as I was, I had no intention of going to bed as long as there was any reasonable chance of Bascomb's return. Even if I did so, I should certainly be unable to sleep, and I should probably have the additional joy of being hauled out in the middle of the night in order to unbolt the door and let him into the house. So, providing myself with one of Uncle Richard's biggest cigars, I refilled my glass again, and wheeled the sofa round in front of the fire. Then, taking Manning's revolver out of my pocket, I laid it carefully on the table beside my tumbler. Although its original owner might still be too indisposed to threaten any immediate danger, there were always Craill and de Roda to be considered. Either of them might take it into his head to pay me a surprise call, and, mentally afflicted as I believed them both to be, they were the sort of visitors for whom it was just as well to be fully prepared. The warmth and stillness of the room soon began to affect me with such a pleasant sense of drowsiness that I found some difficulty in keeping myself awake. In order to assist in the process, I started going over again in my own mind the whole tangled skein of events which had led up to the present crisis. It was an interesting exercise, and, apart from that, it served a double purpose. I was determined to make a clean breast of everything to Bobby the next morning, and, if his advice was to be of any value, it was highly essential that the version I gave him should be an absolutely correct and unprejudiced one. Ten, eleven, and twelve all struck in turn, but outside the house the silence of the night remained unbroken by the faintest sound or movement. Towards one o'clock my desire for sleep became positively overwhelming. By this time any hope I had ever had of Bascomb's putting in an appearance had practically ceased to exist, and it seemed worse than useless to tire myself out to no purpose just when I might need every ounce of energy and intelligence that I could possibly rake together. I debated for a moment as to whether I should go upstairs and get into bed. The prospect had its attractions, but, on the other hand, I felt extremely comfortable where I was, and from a strategic point of view the position could hardly be improved upon. As long as I remained in the hall no one could break into the house without waking me. If I were fast asleep upstairs in my bedroom the odds would be altogether in favour of the visitor, and since the safety of my throat appeared to be the stake at issue, this consideration was quite enough to turn the scale.
