She was no longer to be left in undisturbed possession of her prize. Her movements were watched by two detectives. She was seen to go to the bachelor lodgings of Georges and take away a portable desk, which contained money and correspondence. More mysterious, however, was a visit she paid to the Charonne Cemetery, where she had an interview with an unknown, who was dressed in the clothes of a workman. She left the cemetery alone, and the detectives lost track of her companion. This meeting took place on February 11. Shortly after the widow left Paris with Georges de Saint Pierre for the suburb of Courbevoie. Mace had elicited certain facts from the porter at the Rue de Boulogne and other witnesses, which confirmed his suspicion that the widow had played a sinister part in her lover's misfortune. Her insistence that he should take her to the ball on January 13; the fact that, contrary to the ordinary politeness of a gentleman, he was walking in front of her at the time of the attack; and that someone must have been holding the gate open to enable the assailant to escape it was a heavy gate, which, if left to itself after being opened, would swing too quickly on its hinges and shut of its own accord--these facts were sufficient to excite suspicion. The disappearance, too, of the man calling himself her brother, who had been seen at her apartment on the afternoon of the 13th, coupled with the mysterious interview in the cemetery, suggested the possibility of a crime in which the widow had had the help of an accomplice. To facilitate investigation it was necessary to separate the widow from her lover. The examining magistrate, having ascertained from a medical report that such a separation would not be hurtful to the patient, ordered the widow to be sent back to Paris, and the family of M. de Saint Pierre to take her place. The change was made on March 6. On leaving Courbevoie the widow was taken to the office of Mace. There the commissary informed her that she must consider herself under provisional arrest. "But who," she asked indignantly, "is to look after my Georges?" "His family," was the curt reply. The widow, walking up and down the room like a panther, stormed and threatened. When she had in some degree recovered herself, Mace asked her certain questions. Why had she insisted on her lover going to the ball? She had done nothing of the kind. How was it his assailant had got away so quickly by the open gate? She did not know. What was the name and address of her reputed brother? She was not going to deliver an honest father of a family into the clutches of the police. What was the meaning of her visit to the Charonne Cemetery? She went there to pray, not to keep assignations. "And if you want to know," she exclaimed, "I have had typhoid fever, which makes me often forget things. So I shall say nothing more--nothing--nothing."
