“Absolutely.”
“Did you ever know him ill?”
“Never.”
Holmes popped a sheet of paper before the doctor’s eyes. “Then perhaps you will explain this receipted bill for thirteen guineas, paid by Mr. Godfrey Staunton last month to Dr. Leslie Armstrong, of Cambridge. I picked it out from among the papers upon his desk.”
The doctor flushed with anger.
“I do not feel that there is any reason why I should render an explanation to you, Mr. Holmes.”
Holmes replaced the bill in his notebook. “If you prefer a public explanation, it must come sooner or later,” said he. “I have already told you that I can hush up that which others will be bound to publish, and you would really be wiser to take me into your complete confidence.”
“I know nothing about it.”
“Did you hear from Mr. Staunton in London?”
“Certainly not.”
“Dear me, dear me—the post-office again!” Holmes sighed, wearily. “A most urgent telegram was dispatched to you from London by Godfrey Staunton at six-fifteen yesterday evening—a telegram which is undoubtedly associated with his disappearance—and yet you have not had it. It is most culpable. I shall certainly go down to the office here and register a complaint.”
Dr. Leslie Armstrong sprang up from behind his desk, and his dark face was crimson with fury.
