Some one had crossed the anteroom.

There was a knock at the door.

"Come in!"

The office messenger entered, carrying a card-tray. On the tray was a letter; and in addition there was one of those printed slips on which callers write their name and the object of their visit.

M. Desmalions hastened toward the messenger. He hesitated a moment before taking up the slip. He was very pale. Then he glanced at it quickly.

"Oh!" he said, with a start.

He looked toward Don Luis, reflected, and then, taking the letter, he said to the messenger:

"Is the bearer outside?"

"In the anteroom, Monsieur le Préfet."

"Show the person in when I ring."
