"You are polite to call it a pleasure. I am Richard Darke."

"Can I offer you a glass of champagne, Mr. Darke?"

"There doesn't seem to be any left in the bottle."

"I will order another."

"I won't put you to that trouble. I have business with you, and must request you to go with me."

"But——"

"I can take no denial," said the detective, sharply. "Go up to the desk, settle your bill, and then we will go out together. There will be no scene, and no one will know my errand, if you obey my directions."

Clayton went up to the desk, paid his check, and then, turning to the detective, said,

"I am at your service."
