It occurred to him that the spectacle of a house master wandering abroad on the public highway, carrying a dirty shoe, might be a trifle undignified. You never knew whom you might meet on Sunday afternoon.

Psmith took the shoe, and doing so, understood what before had puzzled him.

Across the toe of the shoe was a broad splash of red paint.

He knew nothing, of course, of the upset tin in the bicycle shed; but when a housemaster's dog has been painted red in the night, and when, on the following day, the housemaster goes about in search of a paint splashed shoe, one puts two and two together. Psmith looked at the name inside the shoe. It was "Brown bootmaker, Bridgnorth." Bridgnorth was only a few miles from his own home and Mike's. Undoubtedly it was Mike's shoe.

"Can you tell me whose shoe that is?" asked Mr. Downing.

Psmith looked at it again.

"No, sir. I can't say the little chap's familiar to me."

"Come with me, then."

Mr. Downing left the room. After a moment Psmith followed him.

The headmaster was in his garden. Thither Mr. Downing made his way, the shoe-bearing Psmith in close attendance.
