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.” “Smith,” said Mr. Downing, trembling with excitement, “go and bring that basket to me here.” Psmith’s brain was working rapidly as he went downstairs. What exactly was at the back of the sleuth’s mind, prompting these manoeuvres, he did not know. But that there was something, and that that something was directed in a hostile manner against Mike, probably in connection with last night’s wild happenings, he was certain. Psmith had noticed, on leaving his bed at the sound of the alarm bell, that he and Jellicoe were alone in the room. That might mean that Mike had gone out through the door when the bell sounded, or it might mean that he had been out all the time. It began to look as if the latter solution were the correct one. * * * * * He staggered back with the basket, painfully conscious the while that it was creasing his waistcoat, and dumped it down on the study floor. Mr. Downing stooped eagerly over it. Psmith leaned against the wall, and straightened out the damaged garment. “We have here, sir,” he said, “a fair selection of our various bootings.” Mr. Downing looked up. “You dropped none of the boots on your way up, Smith?” “Not one, sir. It was a fine performance.” Mr. Downing uttered a grunt of satisfaction, and bent once more to his task. Boots flew about the room. Mr. Downing knelt on the floor beside the basket, and dug like a terrier at a rat-hole. At last he made a dive, and, with an exclamation of triumph, rose to his feet. In his hand he held a boot. “Put those back again, Smith,” he said. The ex-Etonian, wearing an expression such as a martyr might have worn on being told off for the stake, began to pick up the scattered footgear, whistling softly the tune of “I do all the dirty work,” as he did so. “That’s the lot, sir,” he said, rising. “Ah. Now come across with me to the headmaster’s house. Leave the basket here. You can carry it back when you return.” “Shall I put back that boot, sir?”
