"I can hear nothing," I whispered.

She looked over her shoulder to the door. I motioned her not to move. I walked noiselessly to the door, and noiselessly turned the handle. I opened the door for the space of an inch; all was quiet in the house.

"Yet I heard a voice," she said, and the next moment I heard it too.

The candles were alight. I crossed the room and squashed them with the palm of my hand. I was not a moment too soon, for even as I did so I heard the click of a door handle, and then a creak of the hinges, and a little afterwards--footsteps.

A hand crept into mine; we waited in the darkness, holding our breath. The footsteps came down the passage to the door behind which we stood and passed on. I expected that they would be going towards the room in which Helen slept. I waited for them to cease that I might follow and catch Cullen Mayle, damned by some bright proof in his hand of a murderous intention. But they did not cease; they kept on and on. Surely he must have reached the room. At last the footsteps ceased. I opened the door cautiously and heard beneath me in the hall a key turn in a lock.

A great hope sprang up in me. Suppose that since his plan had failed, and since Tortue waited for him on Tresco, he had given up! Suppose that he was leaving secretly, and for good and all! If that supposition could be true! I prayed that it might be true, and as if in answer to my prayer I saw below me where the hall door should be a thin slip of twilight. This slip broadened and broadened. The murmur of the waves became a roar. The door was opening--no, now it was shutting again; the twilight narrowed to a slip and disappeared altogether.

"Listen," said I, and we heard footsteps on the stone tiles of the porch.

"Oh, he is gone!" said Helen, in an indescribable accent of relief.

"Yes, gone," said I. "See, the door of his room is open."

I ran down the passage and entered the room. Helen followed close behind me.
