“Yes; young Daulat Ras, an Indian student who lives on the same stair, came in to ask me some particulars about the examination.”

“For which he was entered?”

“Yes.”

“And the papers were on your table?”

“To the best of my belief they were rolled up.”

“But might be recognised as proofs?”

“Possibly.”

“No one else in your room?”

“No.”

“Did anyone know that these proofs would be there?”

“No one save the printer.”

“Did this man Bannister know?”

“No, certainly not. No one knew.”

“Where is Bannister now?”

“He was very ill, poor fellow. I left him collapsed in the chair. I was in such a hurry to come to you.”

“You left your door open?”

“I locked up the papers first.”

“Then it amounts to this, Mr. Soames, that unless the Indian student recognised the roll as being proofs, the man who tampered with them came upon them accidentally without knowing that they were there.”

“So it seems to me.”

Holmes gave an enigmatic smile.

On the ground floor was the tutor's room. Above were three students, one on each story. It was already twilight when we reached the scene of our problem. Holmes halted and looked earnestly at the window. Then he approached it, and, standing on tiptoe with his neck craned, he looked into the room.
