“Superb little actor!” he laughed in spite of himself, and stooped to stroke the shining black back. But, in a flash, as he touched its fur, the cat turned and spat at him viciously, striking at his hand with one paw.

John Silence straightened himself up and drew a long breath. He realised that the performance was temporarily at an end. The collie, meanwhile, who had watched the whole proceeding with marked disapproval, had now lain down again upon the mat by the fire, no longer growling. It seemed to the doctor just as though something that had entered the room while he slept, alarming the dog, yet bringing happiness to the cat, had now gone out again, leaving all as it was before. Whatever it was that excited its blissful attentions had retreated for the moment.
