When his baggage had been stowed away, and his rugs spread out to make the seat more comfortable still, M. Etienne Rambert repeated his appeal, for he was an old traveller and knew that it does not do to rely too much upon the promises of chance attendants.

"I can rely upon you, can't I? I may sleep as sound as I like, and you will wake me at Verrières?" And the more to assure himself that the guard would execute his orders he slipped a franc into his hand.

When he was left alone, M. Rambert continued his preparations for the night. He carefully drew down the blinds over the door and over the windows of the compartment that gave on to the corridor, and also lowered the shade over the electric light, and then, in order to enjoy the last puffs at his cigar in peace, he opened the window over the other door and leant his elbows on it, watching the final preparations being made by the travellers by the express on the other line.

The departure of a train is always a picturesque sight, and M. Rambert leant forward inquisitively to note how the passengers had installed themselves in the two compartments which he could see from his coign of vantage.

There were not many people in the train. As a matter of fact the Brives and Luchon line is not much used at this time of year. If the number of passengers in the express were any criterion Etienne Rambert might reasonably expect that he would be the only one in the slow train. But there was not much time for observations and reflections of this kind. On the platform for the express, which he got a glimpse of through the compartments, people were hurrying up their farewells. The passengers had got into their carriages, and the friends who had come to see them off were standing alone upon the platform. There was the sound of safety locks being fastened by porters, and the noise of trollies being wheeled along bearing articles for sale.

"Pillows! Rugs! Sweets! Papers!"

Then came the whistle of the guard, the shriller scream from the electric engine, and then, slowly at first but steadily, more rapidly as the engine got up speed, the express moved along the platform and plunged into the tunnel on the way to Austerlitz.

Meanwhile the guard of the slow train was doing wonders. Shamelessly resolved to assure perfect quiet to "his" passenger, he managed, without unduly compromising himself but yet without leaving any doubt about it in any mind, to insinuate discreetly that M. Rambert's carriage was reserved, so that that gentleman might count upon an entirely undisturbed night.

A few minutes after the express had gone, the slow train drew out in its turn, and disappeared into the darkness of the underground tunnel.
