Never in the annals of police history has a detective officer been so long engaged in the search for a fugitive from justice as in the case I am about to relate. There have been and are many men "wanted" for whom warrants are held indefinitely, but never before has an officer spent ten entire months with but one aim--to "get his man," and that after an interregnum of more than seven years. On June 3rd, 1900, the Baroness de Martigny, of Paris, took into her employment as footman an intelligent, good-looking young man, who had previously been in the service of General Pellissier, of the French army. The Baroness, the grand-daughter of a famous soldier who had been one of Napoleon's closest friends, lived in a beautiful hotel in the Avenue du Bois de Boulogne, and also occupied a villa for the season each year at Nice. Her collection of jewels was the envy of the ladies of the French aristocracy, and she had times without number been offered enormous sums for them by dealers and collectors. Many of the ornaments had once belonged to the Queens of France, and one pearl necklace was even said to have at one time adorned the person of an Egyptian princess famous in history. These jewels were always kept in a leather-covered steel box, made expressly for the purpose. When not deposited at her bankers', this box was in the keeping of a trusted maid, who was in turn guarded by a "valet de pied" at times when the Baroness might have occasion to take her jewels with her when travelling. In December, 1900, the Baroness, accompanied by two maids and the valet engaged some months before, was to travel to London for a few days' stay in the capital on a visit to friends. She seldom carried all her jewels with her, but on this occasion she did so, as an august personage had expressed a desire to see them. Two servants of the bank, under the eye of a sub-manager, had delivered the morocco-covered box to the Baroness in person, and she in turn gave it over to her maid, Marcelle. All the luggage had gone on ahead, and the brougham was at the door to take the Baroness to the Gare St. Lazare Station, when the maid, Marcelle, came running into the lady's presence and attempted to speak. Her tongue refused to move, however, and there the girl stood, her eyes almost out of her head, shivering from head to foot. When at last she gained control of herself she stammered, "Madame--the jewel-case--it is gone!" The Baroness tried to get the girl into a rational frame of mind, saying the box could not have been removed from the house; Marcelle must have placed it somewhere else than in its accustomed place. No; the girl was positive she had put the treasure-box on milady's dressing-table just for a moment while she had gone for her hat and coat. When she returned the case was gone!
