“And you call that the whole story!” exclaimed the baron.

“Yes, and if you will listen to me for a few minutes, I think I can convince you. In the first place, a lady who signs herself 540 implores the protection of Arsène Lupin, who replies by asking for particulars. The lady replies that she is under the domination of an enemy—who is Bresson, no doubt—and that she is lost if some one does not come to her assistance. Lupin is suspicious and does not yet venture to appoint an interview with the unknown woman, demands the address and proposes to make an investigation. The lady hesitates for four days—look at the dates—finally, under stress of circumstances and influenced by Bresson’s threats, she gives the name of the street—Murillo. Next day, Arsène Lupin announces that he will be in the Park Monceau at three o’clock, and asks his unknown correspondent to wear a bouquet of violets as a means of identification. Then there is a lapse of eight days in the correspondence. Arsène Lupin and the lady do not require to correspond through the newspaper now, as they see each other or write directly. The scheme is arranged in this way: in order to satisfy Bresson’s demands, the lady is to carry off the Jewish lamp. The date is not yet fixed.

Everything occurs then exactly as Lupin had foreseen. The officers of the law, deceived by an open window, four holes in the ground and two scratches on the balcony railing, immediately advance the theory that the theft was committed by a burglar. The lady is safe.”

“Yes, I confess the theory was a logical one,” said the baron. “But the second theft—”

“The second theft was provoked by the first. The newspapers having related how the Jewish lamp had disappeared, some one conceived the idea of repeating the crime and carrying away what had been left. This time, it was not a simulated theft, but a real one, a genuine burglary, with ladders and other paraphernalia—”
