"Yes."

"Meaning that the part played by myself strikes you as suspicious?"

M. Desmalions hesitated. His eyes met Don Luis's eyes; and he was visibly impressed by the other's frank glance. Nevertheless he replied, plainly and bluntly:

"It is not for you to ask me questions, Monsieur."

Don Luis bowed.

"I am at your orders, Monsieur le Préfet."

"Please tell us what you know."

Don Luis thereupon gave a minute account of events, after which M.
Desmalions reflected for a few moments and said:

"There is one point on which we want to be informed. When you entered this room at half-past two this morning and sat down beside M. Fauville, was there nothing to tell you that he was dead?"

"Nothing, Monsieur le Préfet. Otherwise, Sergeant Mazeroux and I would have given the alarm."
