"You have missed a knife though, have you not?" asked Superintendent Galloway.
"Yes, sir."
"What sort of a knife?"
"A table-knife."
"Was it one of the knives sent up to the sitting-room last night?"
"Yes, sir. At least Charles says so. He has charge of the cutlery."
"Then Charles had better tell us about it," interposed the chief constable. "You say you went to bed before ten o'clock, Benson. Did you hear anything in the night?"
"No, sir, I fell asleep almost immediately. My room is a good distance from Mr. Glenthorpe's room."
"I do not think we have any more questions to ask you, Benson."
"Pardon the curiosity of a medical man, Mr. Cromering," remarked Sir Henry, "but would it be possible to ask the innkeeper whether he noticed anything peculiar about Mr. Ronald's demeanour, when he arrived at the inn, or when he saw him at dinner subsequently?"
