Vargus went to a tall mirror by the piano, as I watched him breathlessly. He did something that I could not see, and it swung open like a door. There was the snap of an electric switch, and I saw him step into a lift, pull a rope, and sink out of sight, leaving the door open.

He could not have sunk ten feet when I was in the room. It was large and square, furnished with something like luxury, and brilliantly lit with electric globes.

There was an arm-chair in full view of the archway. I sat down, and it was still warm from its last occupant. That seemed to me amusing, and I smiled.

Something clanked, a soft swishing noise changed to a distant rumble, and the lift came into sight. I had it covered, but it was empty—waiting for the man who was going to "feed the canaries."

I waited for him, too. There was a box of cigarettes close by. I lit one and smoked quietly. Then I heard him coming through the dining-room, his footsteps and the rattle of a tray.

The half-drawn curtain bellied out and was pushed aside. Feddon stood there with the tray in his hands and the light shining on his ugly red hair.

He saw me. His mouth opened and his eyes started out. He seemed unutterably foolish, like a great cod, and I laughed aloud.

But he was quick, oh, quick and clever! Like the famous footballer that he was! In a second he had ducked, and the loaded tray was skimming across the room straight at my head, as he hurled himself after it, quick as a snake strikes.

I was ready, though. He was not. My first shot broke his shoulder and stopped him for an instant. Then, with a roar of pain and fury, he came on again, and I shot him through the heart when he was three feet away.

Mr. Feddon would feed no more canaries.
