"I was only wondering, sir. Shall I show you the next in order?"
"Certainly."
They moved on up the passage.
Drawing blank at the last dormitory, Mr. Downing paused, baffled. Psmith waited patiently by. An idea struck the master.
"The studies, Smith," he cried.
"Aha!" said Psmith. "I beg your pardon, sir. The observation escaped me unawares. The frenzy of the chase is beginning to enter into my blood. Here we have--"
Mr. Downing stopped short.
"Is this impertinence studied, Smith?"
"Ferguson's study, sir? No, sir. That's further down the passage. This is Barnes'."
Mr. Downing looked at him closely. Psmith's face was wooden in its gravity. The master snorted suspiciously, then moved on.
"Whose is this?" he asked, rapping a door.
"This, sir, is mine and Jackson's."
"What! Have you a study? You are low down in the school for it."
"I think, sir, that Mr. Outwood gave it us rather as a testimonial to our general worth than to our proficiency in school-work."
Mr. Downing raked the room with a keen eye. The absence of bars from the window attracted his attention.
"Have you no bars to your windows here, such as there are in my house?"
"There appears to be no bar, sir," said Psmith, putting up his eyeglass.
Mr Downing was leaning out of the window.
"A lovely view, is it not, sir?" said Psmith. "The trees, the field, the distant hills--"
Mr. Downing suddenly started. His eye had been caught by the water-pipe at the side of the window. The boy whom Sergeant Collard had seen climbing the pipe must have been making for this study.
He spun round and met Psmith's blandly inquiring gaze. He looked at Psmith carefully for a moment. No. The boy he had chased last night had not been Psmith. That exquisite's figure and general appearance were unmistakable, even in the dusk.
"Whom did you say you shared this study with, Smith?"
"Jackson, sir. The cricketer."
"Never mind about his cricket, Smith," said Mr. Downing with irritation.
"No, sir."
"He is the only other occupant of the room?"
"Yes, sir."
"Nobody else comes into it?"
"If they do, they go out extremely quickly, sir."
"Ah! Thank you, Smith."
"Not at all, sir."
Mr. Downing pondered. Jackson! The boy bore him a grudge. The boy was precisely the sort of boy to revenge himself by painting the dog Sammy. And, gadzooks! The boy whom he had pursued last night had been just about Jackson's size and build!
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.
