in this room. If anything has been moved it may put me off the scent altogether. Let me have the details, inspector."
The inspector reported the arrival of the Duke at the police-station with Arsène Lupin's letter to M. Gournay-Martin; the discovery that the keys had been changed and would not open the door of the house; the opening of it by the locksmith; the discovery of the concierge and his wife gagged and bound.
"Probably accomplices," said M. Formery.
"Does Lupin always work with accomplices?" said the Duke. "Pardon my ignorance—but I've been out of France for so long—before he attained to this height of notoriety."
"Lupin—why Lupin?" said M. Formery sharply.
"Why, there is the letter from Lupin which my future father-in-law received last night; its arrival was followed by the theft of his two swiftest motor-cars; and then, these signatures on the wall here," said the Duke in some surprise at the question.
"Lupin! Lupin! Everybody has Lupin on the brain!" said M. Formery impatiently. "I'm sick of hearing his name. This letter and these signatures are just as likely to be forgeries as not."
