In the office, M. Lenormand found a few letters addressed to Mr. Kesselbach. He handed them to the examining-magistrate. There was also a parcel that had just come by the Paris parcel-post. The paper in which it was packed was partly torn; and M. Lenormand saw that it held a small ebony box, engraved with the name of Rudolf Kesselbach. Feeling curious, he opened the parcel. The box contained the fragments of a looking-glass which had evidently been fixed to the inside of the lid. It also contained the card of Arsène Lupin. But one detail seemed to strike the chief detective. On the outside, at the bottom of the box, was a little blue-edged label, similar to the label which he had picked up in the room on the fourth floor where the cigarette-case was found, and this label bore the same number, 813. CHAPTER III M. LENORMAND OPENS HIS CAMPAIGN "Auguste, show M. Lenormand in." The messenger went out and, a few seconds later, announced the chief of the detective-service. There were three men in the prime minister's private room on the Place Beauvau: the famous Valenglay, leader of the radical party for the past thirty years and now president of the council and minister of the interior; the attorney-general, M. Testard; and the prefect of police, Delaume. The prefect of police and the attorney-general did not rise from the chairs which they had occupied during their long conversation with the prime minister. Valenglay, however, stood up and, pressing the chief detective's hand, said, in the most cordial tones: "I have no doubt, my dear Lenormand, that you know the reason why I asked you to come." "The Kesselbach case?" "Yes." * * * * * The Kesselbach case! Not one of us but is able to recall not only the main details of this tragic affair, the tangled skein of which I have set myself to unravel, but even its very smallest incidents, so greatly did the tragedy excite us all during these recent years. Nor is there one of us but remembers the extraordinary stir which it created both in and outside France. And yet there was one thing that upset the public even more than the three murders committed in such mysterious circumstances, more than the detestable atrocity of that butchery, more than anything else; and that was the reappearance--one might almost say the resurrection--of Arsène Lupin. Arsène Lupin! No one had heard speak of him for over four years, since his incredible, his astounding adventure of the Hollow Needle,[2] since the day when he had slunk away into the darkness before the eyes of Holmlock Shears and Isidore Beautrelet, carrying on his back the dead body of the woman whom he loved, and followed by his old servant, Victoire.
