Mr. Downing was as firmly convinced at that moment that Mike’s had been the hand to wield the paint-brush as he had ever been of anything in his life.

“Smith!” he said excitedly.

“On the spot, sir,” said Psmith affably.

“Where are Jackson’s boots?”

There are moments when the giddy excitement of being right on the trail causes the amateur (or Watsonian) detective to be incautious. Such a moment came to Mr. Downing then. If he had been wise, he would have achieved his object, the getting a glimpse of Mike’s boots, by a devious and snaky route. As it was, he rushed straight on.

“His boots, sir? He has them on. I noticed them as he went out just now.”

“Where is the pair he wore yesterday?”

“Where are the boots of yester-year?” murmured Psmith to himself. “I should say at a venture, sir, that they would be in the basket downstairs. Edmund, our genial knife-and-boot boy, collects them, I believe, at early dawn.”

“Would they have been cleaned yet?”

“If I know Edmund, sir—no.”
