When night closed in, Jacques became doubly prudent. Rarely had he found La Lison so obedient. He handled the engine as he pleased, with the absolute will of the master; and yet he did not relax his severity, but treated it as a tamed animal that must always be distrusted.
There, behind his back, in the train, whirling along at express speed, he saw a delicate, confiding, smiling face. He felt a slight shiver. With a firmer hand he grasped the reversing-wheel, piercing the increasing darkness with fixed eyes, in search of red lights. After the embranchments at Asnières and Colombes, he breathed a little. As far as Mantes all went well, the line was as a sheet of glass, and the train rolled along at ease.
After Mantes he had to urge La Lison on, so that it might ascend a rather steep incline, almost half a league long. Then, without slackening speed, he ran down the gentle slope to the Rolleboise tunnel, just about two miles in length, which he negotiated in barely three minutes. There remained but one more tunnel, that of La Roule, near Gaillon, before the station of Sotteville—a spot to be feared, for the complication of the lines, the continual shunting proceeding there, and the constant obstruction, made it exceedingly dangerous. All the strength of his being lay in his eyes which watched, in his hand which drove; and La Lison, whistling and smoking, dashed through Sotteville at full steam, only to stop at Rouen, whence it again set out, a trifle calmer, ascending more slowly the incline that extends as far as Malaunay.
A very clear moon had risen, shedding a white light, by which Jacques was able to distinguish the smallest bushes, and even the stones on the roads, in their rapid flight. As he cast a glance to the right, on leaving the tunnel of Malaunay, disturbed at the shadow cast across the line by a great tree, he recognised the out-of-the-way corner, the field full of bushes, whence he had witnessed the murder. The wild, deserted country flew past, with its continuous hills, its raw black patches of copses, its ravaged desolation. Next, at La Croix-de-Maufras, beneath the motionless moon, abruptly appeared the vision of the atrociously melancholy house set down aslant in its abandonment and distress, with its shutters everlastingly closed. And without understanding why, Jacques, this time again, and more vigorously than on previous occasions, felt a tightening at the heart as if he was passing before his doom.
But immediately afterwards, his eyes carried another image away. Near the house of the Misards, against the gate at the level crossing, stood Flore. He now saw her at this spot at each of his journeys, awaiting, on the watch for him. She did not move, she simply turned her head so as to be able to get a longer view of him in the flash that bore him away. Her tall silhouette stood out in black, against the white light, her golden locks alone being illumined by the pale gold of the celestial body.
And Jacques, having urged on La Lison, to make it scale the ascent at Motteville, allowed the engine breathing time across the plateau of Bolbec. But he finally sent it on again, from Saint-Romain to Harfleur, down the longest incline on the line, a matter of three leagues, which the engines devour at the gallop of mad cattle sniffing the stable. And he was broken down with fatigue at Havre, when, beneath the iron marquee, full of the uproar and smoke at the arrival, Séverine, before going up to her rooms, ran to say to him, in her gay and tender manner:
"Thanks. We may see one another to-morrow."
