I thought it better to keep the matter a secret."
"And you did quite right. I wanted your husband to take up this case, quite independently, and without it being known to anyone that he was in my employ." He paused for a moment in deep thought. "No doubt his employment by Mr. Stapleton is to be kept equally secret."
"I suppose so. He asked me not to say anything about it. I had to tell you, to explain matters."
"And he doesn't know that you are in Paris?" The Prefect gave a sudden laugh. "Ma foi!– what a joke!"
"A joke?"
"Assuredly! Don't you see? I am going to ask you to take up this case, yourself. I must use every means to recover the child of this Stapleton, before others do so for him. My professional pride will not permit me to be beaten. If I can't have your husband, at least I shall have you."
"But – I shall be working in opposition to him."
"Not in opposition. You will both have the same object in view – the recovery of Mr. Stapleton's boy. Whichever of you does so first, the result will be the same – the boy will be restored to his parents. But I want you, my child, to be the one to do this."
"But, Monsieur Lefevre, I could not hope to accomplish anything – where trained men have failed."
"Who knows? I remember well the assistance you gave us, in the matter of the ivory snuff box. Without your help, we should never have recovered it. I have faith in a woman's intuition. You will find this child for me, and give your husband the surprise of his life."
"But," said Grace, smiling mischievously at the prospect which opened before her, "suppose he should see me?"
"You must disguise yourself somewhat. Change the color of your hair; it is easily done – here in Paris." The Prefect laughed. "A slight alteration in appearance only will be necessary. And do not recognize your husband, should you meet him face to face. That is most important."
"Why?"
"Because, should he become convinced that it is really you, I fear he would insist upon your dropping the case entirely, and that would not suit my plans at all. Come, my child." The Prefect's eyes twinkled with amusement. "Do this thing for me. It will be a little joke, between us. The honeymoon detectives, I called you, once. What an amusing thing, that now you should be working in competition with each other, on the same case!" He began to laugh heartily.
"Well," said Grace, her sense of mischief getting the better of her, "now that I'm here, I suppose I might as well keep busy. Richard won't be here for two days, and I may find out something in that time."
"Excellent!" The Prefect clapped his hand smartly upon his knee. "You have two days' start. In two days, much may be accomplished. Come, let us go over the case in detail."
An hour later, Grace left the Prefect's office in a taxicab, having arranged to have her baggage sent to Monsieur Lefevre's house, where she was to stay while in Paris. Her previous acquaintance with Madame Lefevre made this an ideal arrangement. She was to pose as a friend, in Paris on a visit.
She ordered the driver of the taxicab to take her to Mr. Stapleton's house in the Avenue Kleber.
She found Mrs. Stapleton to be a very pretty and stylish woman of thirty; whose beauty, however, was sadly marred by the intense suffering through which she was passing. The poor creature had scarcely slept for over a week, and her distress was pitiable.
She answered Grace's questions as well as she could, under the circumstances. There was, after all, little to say. The nurse, it appeared, stuck to her story – that the boy had vanished, in the twinkling of an eye, while her back had been turned for but a few moments. Mrs. Stapleton could offer no explanation – attempted none.
"It is all so mysterious – so terrible!" she cried. "Poor Mary – she is too ill to see you, I fear, or I would have her tell you the story herself."
"Too ill?" inquired Grace, who had come more to question the maid, than Mrs. Stapleton. "What is the matter with her?"
"They tried to poison her – last Friday."
"They? Who?"
"I do not know. She went out for a walk. The poor woman was half dead, from nervous exhaustion and loss of sleep. She tells me that she stopped to get a cup of chocolate at a café in the Rue St. Honoré. After that she came back to the Champs Élysées, and sat upon a bench. She began suddenly to feel deathly ill, and, calling a cab, was driven home. When she arrived here, she was unconscious, and had to be carried to her room by the servants. She has been in bed ever since. I am glad to say, however, that she is better, and I think she could see you, by morning."
Grace left the Stapleton house, feeling somewhat baffled. The more she heard of this curious affair, the more inexplicable it seemed. She had hoped to visit the scene of the kidnapping, in company with the nurse, and examine the spot with her own eyes. This she now realized she could not do until the following day. She was walking in the direction of the Arc de Triomphe, revolving the affair in her mind, when a young man, evidently a Frenchman, of good appearance and not unpleasant face, came up beside her, bowed politely, and in excellent English asked her regarding Mary Lanahan.
"Miss Lanahan – is she better?" he inquired.
"Who are you, monsieur?" asked Grace, suppressing her inclination to resent the man's action, in her hope that she might learn something from him of value. His question showed Grace at once that he was acquainted with at least one member of the Stapleton household.
"I am a friend of Miss Lanahan's," the man replied. "I hear that she is ill. I saw you enter and leave the house, and I ventured to ask you if she is better."
"I was told that she is. I did not see her."
A peculiar expression crossed the young man's face; but Grace could not determine, so fleeting was it, whether it indicated pleasure or disappointment.
They walked along in silence for a few moments, and had almost reached the arch, when a ragged little urchin, a veritable Paris gamin, came up to Grace's companion and thrust a crumpled bit of paper into his hand, then darted off, whistling shrilly.
The man looked after him a moment, then examined the note. Whatever its contents, they made a startling impression upon him. He looked about, an expression of fear upon his face, turned to Grace with a hurried bow, and a quick good evening, and at once walked off in the opposite direction at full speed, at the same time fumbling in the breast pocket of his coat, as though searching for something in it. In his efforts, he dropped several papers to the street. Grace watched him as he picked them hurriedly up and moved off into the gathering darkness.
She fancied that one of the bits of paper had escaped his notice, and, on going back to the spot, found that she was correct. A small visiting card lay upon the sidewalk. She picked it up, and read the name as she walked away. It was Alphonse Valentin, Boulevard St. Michel.
Grace slipped the card into her pocketbook. The man's name meant nothing to her – she fancied that he was some friend of Miss Lanahan's, concerned about her condition. Yet why did he not inquire for her at the house, in the ordinary way? And why should the note, handed to him by the street urchin, have caused him such evident alarm?
She glanced at her watch, and saw that it was close to seven o'clock. She had intended to return to Monsieur Lefevre's for dinner; but a sudden determination to find out more about this man Valentin caused her to proceed at once to a hotel near the Louvre, where she ate her dinner alone.
An hour later she descended from a cab at the number on the Boulevard St. Michel, which was inscribed upon Alphonse Valentin's card.
The place was a dingy old building, the main floor of which was occupied by a dealer in cheese. A narrow doorway at one side gave access to the upper floors. Grace rang the bell, and waited in some trepidation. This going about Paris at night was rather an unusual experience. She thought of the simple joys of her life at home, and for a moment regretted that she had not stayed there. The opening of the door interrupted her thoughts.
The woman who stood in the hallway regarded her without particular interest, and inquired her business. "I wish to see Monsieur Valentin," said Grace.
"He
