And M. Desmalions yielded.

A few moments later Don Luis Perenna and Florence Levasseur took their seats in a motor car with Weber and two inspectors. Another car, filled with detectives, followed.

The hospital was literally invested by the police force and Weber neglected none of the precautions of a regular siege.

The Prefect of Police, who arrived in his own car, was shown by the manservant into the waiting-room and then into the parlour, where the mother superior came to him at once. Without delay or preamble of any sort he put his questions to her, in the presence of Don Luis, Weber, and Florence:

"Reverend mother," he said, "I have a letter here which was brought to me at headquarters and which tells me of the existence of certain documents concerning a legacy. According to my information, this letter, which is unsigned and which is in a disguised hand, was written by you. Is that so?"

The mother superior, a woman with a powerful face and a determined air, replied, without embarrassment:

"That is so, Monsieur le Préfet. As I had the honour to tell you in my letter, I would have preferred, for obvious reasons, that my name should not be mentioned. Besides, the delivery of the documents was all that mattered. However, since you know that I am the writer, I am prepared to answer your questions."

M. Desmalions continued, with a glance at Florence:

"I will first ask you, Reverend Mother, if you know this young lady?"

"Yes, Monsieur le Préfet. Florence was with us for six months as a nurse, a few years ago. She gave such satisfaction that I was glad to take her back this day fortnight. As I had read her story in the papers, I simply asked her to change her name. We had a new staff at the hospital, and it was therefore a safe refuge for her."
