"That's one clue checked," thought the inspector. "Our man wears an eyeglass."
He next collected the pieces of the racing-paper and showed them to a newsvendor, who easily recognized the Turf Illustré. Ganimard at once went to the offices of the Turf and asked to see the list of subscribers. Going through the list, he jotted down the names and addresses of all those who lived anywhere near the Pont-Neuf and principally—because Lupin had said so—those on the left bank of the river.
He then went back to the Criminal Investigation Department, took half a dozen men and packed them off with the necessary instructions.
At seven o'clock in the evening, the last of these men returned and brought good news with him. A certain M. Prévailles, a subscriber to the Turf, occupied an entresol flat on the Quai des Augustins. On the previous evening, he left his place, wearing a fur coat, took his letters and his paper, the Turf Illustré, from the porter's wife, walked away and returned home at midnight. This M. Prévailles wore a single eyeglass. He was a regular race-goer and himself owned several hacks which he either rode himself or jobbed out.
The inquiry had taken so short a time and the results obtained were so exactly in accordance with Lupin's predictions that Ganimard felt quite overcome on hearing the detective's report. Once more he was measuring the prodigious extent of the resources at Lupin's disposal. Never in the course of his life—and Ganimard was already well-advanced in years—had he come across such perspicacity, such a quick and far-seeing mind.
He went in search of M. Dudouis.
"Everything's ready, chief. Have you a warrant?"
"Eh?"
"I said, everything is ready for the arrest, chief."
"You know the name of Jenny Saphir's murderer?"
