That he was meditating some mischief, however, seemed to me highly probable. Not that I had much belief in the tragic forebodings of Christine and Bascomb, for I rated our friend's intelligence too highly to imagine him to be capable of any such blunder as that of trying to cut my throat while he was a guest under my roof. I was inclined to think that it was a thirst for information rather than a thirst for blood which had prompted his suggestion of an early retirement. My opinion was chiefly based upon what Bascomb had told me about his two previous attempts to get back into the house after my uncle's death. This persistence could only be explained by the theory that he wanted to make some further investigations, and now that he was actually on the spot he was not likely to neglect such a favourable opportunity.

Anyhow, whichever view of the situation was correct, I was faced with the cheerful prospect of spending a sleepless night. It was very annoying, especially as I had to go to town the next day; but my painful experiences at sea have given me a certain amount of philosophy in these matters, and I settled down grimly to make the best of it.

Anyone who has enjoyed a similar ordeal knows with what wearisome slowness the hours can occasionally pass. In my case, I had not even the consolation of a book, for I was afraid of treating myself to a candle in case the light should be visible under the door. I just tumbled into bed and lay there in complete darkness, keeping my eyes wide open and listening intently for the slightest noise.

Through the open window, at amazingly long intervals, I could hear the church clock at Pen Mill chiming out the quarters. Nothing else broke the silence except an occasional rustle in the shrubbery, which told me that Satan was patrolling the garden with his usual trustworthy thoroughness.

Midnight struck, and after a respectable foretaste of eternity between each, one, two, and three eventually followed suit. Very gradually the blackness of night began to slip into the gray twilight of early dawn, and bit by bit the various pieces of furniture in my room emerged into shape out of the surrounding gloom.

Outside, a bird started twittering in the creeper, but everything in the house still remained as quiet as the grave. Try as I would, I found it harder and harder to fight off the drowsiness that was constantly stealing over me, and more than once I only just roused myself in time as I was on the very point of falling asleep.

Whether I eventually dropped off into a doze I can't say. If I did, some important part of me must have remained awake, for I suddenly found myself sitting up in bed, perfectly cool and collected, but with every nerve in my body strained to the utmost attention.

For a moment nothing happened. Then, once again, came the sound that I was waiting for—the faint creak of a board in the passage outside my door.

Turning back the clothes, I slipped noiselessly out of bed. A glance at my watch on the table beside me showed me that it was close on half-past four—a time at which no respectable passage board has any right to indulge in such antics. My long vigil had not been useless, and, standing there in bare feet and pyjamas, I felt that pleasant glow of rewarded virtue which comes occasionally to the least deserving of us.

I made no attempt to rush things, however. Looking round the room, my eyes fell on the poker, which was leaning up invitingly alongside the fireplace. It struck me as being a nice, companionable sort of object, and, having tiptoed across the room and taken possession of it, I returned in the same stealthy fashion to the door.
