Javert had followed Jean Valjean from tree to tree, then from corner to corner of the street, and had not lost sight of him for a single instant; even at the moments when Jean Valjean believed himself to be the most secure Javert’s eye had been on him. Why had not Javert arrested Jean Valjean? Because he was still in doubt.
It must be remembered that at that epoch the police was not precisely at its ease; the free press embarrassed it; several arbitrary arrests denounced by the newspapers, had echoed even as far as the Chambers, and had rendered the Prefecture timid. Interference with individual liberty was a grave matter. The police agents were afraid of making a mistake; the prefect laid the blame on them; a mistake meant dismissal. The reader can imagine the effect which this brief paragraph, reproduced by twenty newspapers, would have caused in Paris: “Yesterday, an aged grandfather, with white hair, a respectable and well-to-do gentleman, who was walking with his grandchild, aged eight, was arrested and conducted to the agency of the Prefecture as an escaped convict!”
Let us repeat in addition that Javert had scruples of his own; injunctions of his conscience were added to the injunctions of the prefect. He was really in doubt.
Jean Valjean turned his back on him and walked in the dark.
Sadness, uneasiness, anxiety, depression, this fresh misfortune of being forced to flee by night, to seek a chance refuge in Paris for Cosette and himself, the necessity of regulating his pace to the pace of the child—all this, without his being aware of it, had altered Jean Valjean’s walk, and impressed on his bearing such senility, that the police themselves, incarnate in the person of Javert, might, and did in fact, make a mistake. The impossibility of approaching too close, his costume of an émigré-preceptor, the declaration of Thénardier which made a grandfather of him, and, finally, the belief in his death in prison, added still further to the uncertainty which gathered thick in Javert’s mind.
