But the doctor had stopped short, and was staring at the house, while, once again, every vestige of colour had left his face.

"My God!" he muttered, "there's a light in the room.... A light, man; don't you see it?"

"I left the candles burning," I said, impatiently. "Really, doctor, I suppose murder doesn't often come your way, but..."

I walked on quickly and he followed. Really the fuss was getting on my nerves, already distinctly ragged. The front door was open as I had left it, and I paused for a moment in the cobwebby hall. Then, pulling myself together, I stepped into the room where the body lay, to halt and stare open-mouthed at the floor....

The candles still flickered on the mantelpiece; the furniture was as I had left it; but of the body of John Trelawnay there was not a trace. It had vanished utterly and completely.

"I don't understand, doctor," I muttered foolishly. "I left the body lying there."

The doctor stood at the door beside me, and suddenly I realized that his eyes were fixed on me.

"I know," he said, and his voice was grave and solemn. "With the head near that chair."

"Why, how do you know?" I cried, amazed. "Have you taken the body away?"
