A silence ensued. M. Desmalions once more inspected this curious individual; and he could not refrain from saying, as though in obedience to an association of ideas for which he himself was unable to account:
"One word more, and one only. What were your comrades' reasons for giving you that rather odd nickname of Arsène Lupin? Was it just an allusion to your pluck, to your physical strength?"
"There was something besides, Monsieur le Préfet: the discovery of a very curious theft, of which certain details, apparently incapable of explanation, had enabled me to name the perpetrator."
"So you have a gift for that sort of thing?"
"Yes, Monsieur le Préfet, a certain knack which I had the opportunity of employing in Africa on more than one occasion. Hence my nickname of Arsène Lupin. It was soon after the death of the man himself, you know, and he was much spoken of at the time."
"Was it a serious theft?"
"It was rather; and it happened to be committed upon Cosmo Mornington, who was then living in the Province of Oran. That was really what started our relations."
There was a fresh silence; and Don Luis added:
"Poor Cosmo! That incident gave him an unshakable confidence in my little detective talents. He was always saying, 'Perenna, if I die murdered'—he had a fixed notion in his head that he would meet with a violent death—'if I die murdered, swear that you will pursue the culprit.'"
"His presentiment was not justified," said the Prefect of Police. "Cosmo
Mornington was not murdered."
