"Monsieur le Duc," Guy answered, "I can assure you that I appreciate all that you have said. I am willing to do exactly as you say."

"To-morrow morning's papers," the Duke said slowly, "will contain an account of the finding of your body in the Seine."

"My what!" Guy exclaimed.

"Your body! We are going to stab and drown you. Perhaps I should say we are going to discover you stabbed and drowned."

Guy half rose from his seat.

"I say——" he began.

"I need not explain, of course," the Duke continued, "that you will suffer by proxy. The whole affair has been carefully arranged by the commissioners of police.

"An account of your doings since you arrived in Paris will be given, which I fear may not flatter you, but you must remember that it is necessary to put our German friends completely off the scent, and in a month's time or so you will reappear, and everything will be contradicted."

"But my sister?" Guy exclaimed.

"Concerning your sister," the Duke continued, "we have further explanations, perhaps I should say apologies, to offer you at some future time. For the present—this only. She is now in Paris. She is to some extent in our confidence, and you shall see her within the next few days."
