Simon, re-entering the bedroom, bath towel in hand, began to dress, Mudd handing things which Simon took as though half oblivious of the presence of the other. He seemed engaged in some happy vein of thought.

Dressed and smart, but unshaved, though scarcely showing the fact, Simon took the two pounds ten and put it in his pocket, then he looked at Mudd. His expression had changed somewhat; he seemed working out some problem in his mind.

"That will do," said he; "I won't want you any more for a few minutes. I want to arrange things. You can go down and come back in a few minutes."

Mudd hesitated. Then he went.

He heard Simon lock the door. He went into an adjoining corridor and walked up and down, dumbly praying that Mr. Robert would come—confused, agitated, wondering.... Suppose Simon wanted to be alone to cut his throat! The horror of this thought was dispelled by the recollection that there were no razors about; also by the remembered cheerfulness of the other. But why did he want to be alone?

Two minutes passed, three, five—then the intrigued one, making for the closed door, turned the handle. The door was unlocked, and Simon, standing in the middle of the room, was himself again.

"I've got a message I want you to take," said Simon.

Ten minutes later Mr. Robert Ravenshaw, entering the Charing Cross Hotel, found Mudd with his hat on, waiting for him.

"Thank the Lord you've come, Mr. Robert!" said Mudd.
