Arsène Lupin in our midst! the irresponsible burglar whose exploits had been narrated in all the newspapers during the past few months! the mysterious individual with whom Ganimard, our shrewdest detective, had been engaged in an implacable conflict amidst interesting and picturesque surroundings. Arsène Lupin, the eccentric gentleman who operates only in the châteaux and salons, and who, one night, entered the residence of Baron Schormann, but emerged empty-handed, leaving, however, his card on which he had scribbled these words: Arsène Lupin, gentleman-burglar, will return when the furniture is genuine.
