"Monsieur le Prefet, we are in sight of the goal. I know the road that will lead us to it. The wild beast shall be hunted down to-night, or to-morrow at least. Monsieur le Prefet, the letter that accompanied those doc.u.ments, the unsigned letter which this young lady handed you, was written by the mother superior who manages a nursing-home in the Avenue des Ternes.

"By making immediate inquiries at that nursing-home, by questioning the superior and confronting her with Mlle. Leva.s.seur, we shall discover the ident.i.ty of the criminal himself. But we must not lose a minute, or we shall be too late and the wild beast will have fled."

His outburst was irresistible. There was no fighting against the violence of his conviction. Still, M. Desmalions objected:

"Mlle. Leva.s.seur could tell us--"

"She will not speak, or at least not till later, when the man has been unmasked in her presence. Monsieur le Prefet, I entreat you to have the same confidence in me as before. Have not all my promises been fulfilled?

Have confidence, Monsieur le Prefet; cast aside your doubts. Remember how Marie Fauville and Gaston Sauverand were overwhelmed with charges, the most serious charges, and how they succ.u.mbed in spite of their innocence.

"Does the law wish to see Florence Leva.s.seur sacrificed as the two others were? And, besides, what I ask for is not her release, but the means to defend her--that is to say, an hour or two's delay. Let Deputy Chief Weber be responsible for her safe custody. Let your detectives go with us: these and more as well, for we cannot have too many to capture the loathsome brute in his lair."

M. Desmalions did not reply. After a brief moment he took Weber aside and talked to him for some minutes. M. Desmalions did not seem very favourably disposed toward Don Luis's request. But Weber was heard to say:

"You need have no fear, Monsieur le Prefet. We run no risk."

And M. Desmalions yielded.

A few moments later Don Luis Perenna and Florence Leva.s.seur 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 doc.u.ments 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 embarra.s.sment:

"That is so, Monsieur le Prefet. 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 doc.u.ments 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 Prefet. 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."

"But, as you have read the papers, you must be aware of the accusations against her?"

"Those accusations have no weight, Monsieur le Prefet, with any one who knows Florence. She has one of the n.o.blest characters and one of the strictest consciences that I have ever met with."

The Prefect continued:

"Let us speak of the doc.u.ments, Reverend Mother. Where do they come from?"

"Yesterday, Monsieur le Prefet, I found in my room a communication in which the writer proposed to send me some papers that interested Florence Leva.s.seur--"

"How did any one know that she was here?" asked M. Desmalions, interrupting her.

"I can't tell you. The letter simply said that the papers would be at Versailles, at the _poste restante_, in my name, on a certain day--that is to say, this morning. I was also asked not to mention them to anybody and to hand them at three o'clock this afternoon to Florence Leva.s.seur, with instructions to take them to the Prefect of Police at once. I was also requested to have a letter conveyed to Sergeant Mazeroux."

"To Sergeant Mazeroux! That's odd."

"That letter appeared to have to do with the same business. Now, I am very fond of Florence. So I sent the letter, and this morning went to Versailles and found the papers there, as stated. When I got back, Florence was out. I was not able to hand them to her until her return, at about four o'clock."

"Where were the papers posted?"

"In Paris. The postmark on the envelope was that of the Avenue Niel, which happens to be the nearest office to this."

"And did not the fact of finding that letter in your room strike you as strange?"

"Certainly, Monsieur le Prefet, but no stranger than all the other incidents in the matter."

"Nevertheless," continued M. Desmalions, who was watching Florence's pale face, "nevertheless, when you saw that the instructions which you received came from this house and that they concerned a person living in this house, did you not entertain the idea that that person--"

"The idea that Florence had entered the room, unknown to me, for such a purpose?" cried the superior. "Oh, Monsieur le Prefet, Florence is incapable of doing such a thing!"

The girl was silent, but her drawn features betrayed the feelings of alarm that upset her.

Don Luis went up to her and said:

"The mystery is clearing, Florence, isn't it? And you are suffering in consequence. Who put the letter in Mother Superior's room? You know, don't you? And you know who is conducting all this plot?"

She did not answer. Then, turning to the deputy chief, the Prefect said:

"Weber, please go and search the room which Mlle. Leva.s.seur occupied."

And, in reply to the nun's protest:

"It is indispensable," he declared, "that we should know the reasons why Mlle. Leva.s.seur preserves such an obstinate silence."

Florence herself led the way. But, as Weber was leaving the room, Don Luis exclaimed:

"Take care, Deputy Chief!"

"Take care? Why?"

"I don't know," said Don Luis, who really could not have said why Florence's behaviour was making him uneasy. "I don't know. Still, I warn you--"

Weber shrugged his shoulders and, accompanied by the superior, moved away. In the hall he took two men with him. Florence walked ahead. She went up a flight of stairs and turned down a long corridor, with rooms on either side of it, which, after turning a corner, led to a short and very narrow pa.s.sage ending in a door.

This was her room. The door opened not inward, into the room, but outward, into the pa.s.sage. Florence therefore drew it to her, stepping back as she did so, which obliged Weber to do likewise. She took advantage of this to rush in and close the door behind her so quickly that the deputy chief, when he tried to grasp the handle, merely struck the air.

He made an angry gesture:

"The baggage! She means to burn some papers!"

And, turning to the superior:
