“What is this dead-room?”

“It is a chamber on the ground floor which has a grated window opening on the garden, which is closed on the outside by a shutter, and two doors; one leads into the convent, the other into the church.”

“What church?”

“The church in the street, the church which anyone can enter.”

“Have you the keys to those two doors?”

“No; I have the key to the door which communicates with the convent; the porter has the key to the door which communicates with the church.”

“When does the porter open that door?”
