It all occupied only a few minutes, and then Andrews, slowly opening his rigidly crooked fingers, stood panting and looking down at the distorted face of the dead man.

For once in his life the Scotsman was sober, and turning to Dr. Kreener:

“I have waited seven long years for this,” he said, “and I'll hang wi' contentment.”

I can never forget the ensuing moments, in which, amid a horrible silence broken only by the ticking of a clock and the heavy breathing of Colquhoun (so long known to us as Andrews) we stood watching the contorted body on the settee.

And as we watched, slowly the rigid limbs began to relax, and Tcheriapin slid gently on to the floor, collapsing there with a soft thud, where he squatted like some hideous Buddha, resting back against the cushions, one spectral yellow hand upraised, the fingers still clutching a big gold tassel.

Andrews (for so I always think of him) was seized with a violent fit of trembling, and he dropped into the chair, muttering to himself and looking down wild-eyed at his twitching fingers. Then he began to laugh, high-pitched laughter, in little short peals.

“Here!” cried the doctor sharply. “Drop that!”

Crossing to Andrews, he grasped him by the shoulders and shook him roughly.

The laughter ceased, and:

“Send for the police,” said Andrews in a queer, shaky voice. “Dinna fear but I'm ready. I'm only sorry it happened here.”
