"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 schoolwork."
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.
