Whenever I sit down to tell one of the numberless adventures which compose the life of Arsène Lupin, I feel a genuine embarrassment, because it is quite clear to me that even the least important of these adventures is known to every one of my readers. As a matter of fact, there is not a move on the part of "our national thief," as he has been happily called, but has been described all over the country, not an exploit but has been studied from every point of view, not an action but has been commented upon with an abundance of detail generally reserved for stories of heroic deeds.
Who, for instance, does not know that strange case of the blonde lady, with the curious episodes which were reported under flaring headlines as "NUMBER 514, SERIES 23!" ... "THE MURDER IN THE AVENUE HENRI-MARTIN!" ... and "THE BLUE DIAMOND!" ... What an excitement there was about the intervention of Holmlock Shears, the famous English detective! What an effervescence surrounded the varying fortunes that marked the struggle between those two great artists! And what a din along the boulevards on the day when the newsboys shouted:
"Arrest of Arsène Lupin!"
My excuse is that I can supply something new: I can furnish the key to the puzzle. There is always a certain mystery about these adventures: I can dispel it. I reprint articles that have been read over and over again; I copy out old interviews: but all these things I rearrange and classify and put to the exact test of truth. My collaborator in this work is Arsène Lupin himself, whose kindness to me is inexhaustible. I am also under an occasional obligation to the unspeakable Wilson, the friend and confidant of Holmlock Shears.
My readers will remember the Homeric laughter that greeted the publication of the two telegrams. The name of Arsène Lupin alone was a guarantee of originality, a promise of amusement for the gallery. And the gallery, in this case, was the whole world.
An inquiry was immediately set on foot by the Crédit Foncier and it was ascertained that number 514, series 23, had been sold by the Versailles branch of the Crédit Lyonnais to Major Bressy of the artillery. Now the major had died of a fall from his horse; and it appeared that he told his brother officers, some time before his death, that he had been obliged to part with his ticket to a friend.
"That friend was myself," declared M. Gerbois.
"Prove it," objected the governor of the Crédit Foncier.
