Lanyard made enquiry, found that the train was destined for Le Vigan, on the eastern slope of the Cévennes, and purchased a ticket for that point.
Making himself as comfortable as might be in a depressingly third-rate second-class compartment (there was no first class, and the third was far too richly flavoured for his stomach) he cultivated a doze as the train pulled out. But, driven as provincial trains habitually are, in a high spirit of devil-may-care, its first stop woke him up with a series of savage, back-breaking jolts which were translated into jerks when it started on again and fiendishly reiterated at every suspicion of a way-station on the course. So that he presently abandoned all hope of sleep and sought solace in tobacco and the shifting views afforded by the windows. Penetrating the upper valley of the Cernon, the railroad skirted the southern boundary of the Causse Larzac, then laboriously climbed up to the plateau itself; and Lanyard roused to the fact that he was approaching familiar ground from a new angle: the next stop would be Combe-Redonde.
The day was still in its infancy when that halt was made. Aside from the station agent, not a soul waited upon the platform. But one or two passengers were set down and, as the engine began to snort anew, a man darted from behind the tiny structure that housed ticket-office and waiting-room, galloped heavily across the platform, and with nothing to spare threw himself into the compartment immediately behind that wherein Lanyard sat alone.
This manoeuvre was performed so briskly and unexpectedly that Lanyard caught barely a glimpse of the fellow; but one glimpse was enough to convince him he had been wrong in assuming that Monsieur Albert Dupont had sneaked back to Paris to hide from the authorities after failing to assassinate André Duchemin more than three weeks ago.
But why--assuming one were not misled by a chance likeness to that heavy but athletic figure so well-remembered--why had Dupont lingered so long in the neighbourhood, in hourly peril of arrest? And why this sudden departure in the chill break of dawn, a move so timed and executed that it wore every sign of haste and fear?
No reasonable explanation offered in solution of either of these riddles; unless, indeed, it were reasonable to believe that lust for vengeance was the ruling passion in the Dupont nature, that the creature had hung about the château in hope of getting another chance at Duchemin, and had decided to give it up only on discovering --inexplicably, at this hour--that the latter had stolen away under cover of night. But Lanyard didn't believe that. Neither did he believe that Dupont had had any hand in the robbery of night before last, and was now in tardy flight. In truth, he didn't know what to think, and the wildest flights of an imagination provoked by this mystery were tame and timid in contrast with the truth as he was later to learn it.
To an amateur in sensations there was true piquancy in the thought that one was travelling in company with a thug who had already had two tries for one's life and would not hesitate to essay a third; in the same coach, separated only by the thin partition between the compartments, safe only in the thug's unconsciousness of one's proximity! And this without the privilege of denouncing the man to the police; for to do so now would be to enmesh in the toils of the law not only Albert Dupont, would-be assassin, but André Duchemin, charged with stealing the Montalais jewels.
Lanyard would have given something for a peep-hole in the partition, to be able to study the countenance of Dupont unaware that he was under scrutiny. But he had to content himself with keeping vigil at the windows, making sure that Dupont did not drop off at some one of those many way-stations which the train was so scrupulous never to slight.
Monsieur Dupont, however, did not budge a foot out of his compartment before the end of the run; and then Lanyard, purposely delaying, saw Dupont get down from the compartment astern and make for the booking-office at Le Vigan without a glance to right or left--evidencing not the remotest interest in his late company on the train, but rather a complete indifference, an absolute assurance that he had nothing now to fear, and with this a preoccupation of mind so thoroughgoing that Lanyard was able to edge up behind him, when he paused at the guichet, and eavesdrop on his consultation with the clerk of the ticket bureau.
Dupont desired ardently to proceed to Lyons with the least avoidable delay. Under such conditions, according to the Indicateur des Chemins de Fer, his best available route was via Nimes, where the next express from Le Vigan made close connection with a northbound train rapide, due to arrive in Lyons late in the afternoon.
