"You will presently," Mordaunt assured him. "In the meantime, it really doesn't matter, and it is not the time for explanations. I am very glad to have met you. You surely will not refuse to be my guest for a few hours."

He spoke with the utmost kindness, but also with inflexible determination. The Frenchman still looked dubious, but quite obviously he did not feel equal to a battle of wills with his resolute host. He uttered a sigh and said no more.

Holmes paused. "I've made up the bed in the spare-room, sir," he said.

"Oh, thanks! I shall not want it though. I will sleep on the sofa here."
