And Roubaud, feeling himself being stared at, looked at her, tossing his chin, as if to say that he also considered the matter strange. Beside her, he perceived Pecqueux and Madame Lebleu, tossing their heads as well. All eyes were turned towards him. The crowd awaited something more, sought on his body for a forgotten detail that would throw light on the matter. There was no accusation in these ardently inquisitive looks; and yet, he fancied he noticed a vague suspicion arising, that doubt which the smallest fact sometimes transforms into a certainty.
"Extraordinary," murmured M. Cauche.
"Quite extraordinary," assented M. Dabadie.
Then Roubaud made up his mind.
"What I am, moreover, quite certain of," he continued, "is that the express which runs from Rouen to Barentin without stopping, went along at the regulation speed, and that I noticed nothing abnormal. I mention this, because, as we were alone, I let down the window to smoke a cigarette, and glancing outside several times, had a perfect knowledge of every sound of the train. At Barentin, noticing my successor, the station-master, Monsieur Bessière, on the platform, I called to him, and we exchanged a few words, as he stood on the step, and shook hands. That is so, my dear, is it not? The question can be put to Monsieur Bessière, and he will answer, Yes."
Séverine, still motionless and pale, her delicate face plunged in grief, once more confirmed the statement of her husband.
"Yes, that is correct," said she.
From this moment any accusation was out of the question, if the Roubauds, having returned to their compartment at Rouen, had been greeted, sitting there, by a friend at Barentin. The shadow of suspicion which the assistant station-master had noticed in the eyes of the bystanders, vanished, while the general astonishment increased. The case was assuming a more and more mysterious aspect.
"Come," said the commissary, "are you quite positive that nobody could have entered the coupé at Rouen, after you left Monsieur Grandmorin?"
Roubaud had evidently not foreseen this question. For the first time, he became confused, having no doubt got to the end of his ready answers. He looked at his wife, hesitating.
