It was an old house where Caffie lived, and had been formerly a private hotel; it was composed of two wings, one on the street, the other on an inside court. A porte cochere gave access to this court, and under its roof, near the staircase, was the concierge's lodge. Saniel knocked at the door in vain; it was locked and would not open. He waited several minutes, and in his nervous impatience walked restlessly up and down the court. At last an old woman appeared carrying a small wax taper. She was feeble and bent, and began to excuse herself; she was alone and could not be everywhere at the same time, in her lodge and lighting the lamps on the stairways. Caffie lived on the first floor, in the wing on the street.

Saniel mounted the stairs and rang the bell. A long time passed, or at least it seemed long to him, before there was an answer. At last he heard a slow and heavy step on the tiled floor and the door was opened, but held by a hand and a foot.

"What do you wish?"

"Monsieur Caffie."

"I am he. Who are you?"

"Doctor Saniel."

"I have not sent for a doctor."

"It is not as doctor that I am here, but as client."

"This is not the hour when I receive clients."

"But you are at home."
