But the first taste of spirit dispelled it. Very courteously Bertrand thanked him.

"You are a good man, Holmes. And I think that you are my friend, yes?"

"Very pleased to do anything I can for you, sir," said Holmes.

"Ah! Then I will ask of you one little thing. It is that you remember that this weakness—this malady of a moment—remain a secret between us two—between—us—two. Vous comprenez; non?"

His eyes, very bright and searching, looked with a certain peremptoriness into the man's face, and Holmes, accustomed to obey, made instinctive response.

"You mean as I am not to mention it to Mr. Mordaunt, sir?"

"That is what I mean, Holmes."

"Very good, sir," said Holmes. "You're feeling better, I hope, sir?"
