s 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. Prevailles, 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 Illustre_, from the porter's wife,
walked away and returned home at midnight. This M. Prevailles 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?"

"Yes."

"But how? Explain yourself."

Ganimard had a sort of scruple of conscience, blushed a little and
nevertheless replied:

"An accident, chief. The murderer threw everything that was likely to
compromise him into the Seine. Part of the parcel was picked up and
handed to me."

"By whom?"

"A boatman who refused to give his name, for fear of getting into
trouble. But I had all the clues I wanted. It was not so difficult as I
expected."

And the inspector described how he had gone to work.

"And you call that an accident!" cried M. Dudouis. "And you say that it
was not difficult! Why, it's one of your finest performances! Finish it
yourself, Ganimard, and be prudent."

Ganimard was eager to get the business done. He went to the Quai des
Augustins with his men and distributed them around the house. He
questioned the portress, who said that her tenant took his meals out of
doors,
