His efforts were not absolutely wasted.

After three days’ investigation, he felt comparatively certain that the assassin had not left the train at Rueil, as all the people of Bougival, La Jonchere, and Marly do, but had gone on as far as Chatou.

Tabaret thought he recognized him in a man described to him by the porters at that station as rather young, dark, and with black whiskers, carrying an overcoat and an umbrella.

This person, who arrived by the train which left Paris for St. Germain at thirty-five minutes past eight in the evening, had appeared to be in a very great hurry.

On quitting the station, he had started off at a rapid pace on the road which led to Bougival. Upon the way, two men from Marly and a woman from La Malmaison had noticed him on account of his rapid pace. He smoked as he hurried along.

On crossing the bridge which joins the two banks of the Seine at Bougival, he had been still more noticed.

It is usual to pay a toll on crossing this bridge; and the supposed assassin had apparently forgotten this circumstance. He passed without paying, keeping up his rapid pace, pressing his elbows to his side, husbanding his breath, and the gate-keeper was obliged to run after him for his toll.

He seemed greatly annoyed at the circumstance, threw the man a ten sou piece, and hurried on, without waiting for the nine sous change.

Nor was that all.

The station master at Rueil remembered, that, two minutes before the quarter past ten train came up, a passenger arrived very agitated, and so out of breath that he could scarcely ask for a second class ticket for Paris.
