At La Force this farce had been all the more successful in the first instance because the head of the “safety” force--an abbreviation of the title “Head of the brigade of the guardians of public safety”--Bibi-Lupin, who had long since taken Jacques Collin into custody at Madame Vauquer’s boarding-house, had been sent on special business into the country, and his deputy was a man who hoped to succeed him, but to whom the convict was unknown. Bibi-Lupin, himself formerly a convict, and a comrade of Jacques Collin’s on the hulks, was his personal enemy. This hostility had its rise in quarrels in which Jacques Collin had always got the upper hand, and in the supremacy over his fellow-prisoners which _Trompe-la-Mort_ had always assumed. And then, for ten years now, Jacques Collin had been the ruling providence of released convicts in Paris, their head, their adviser, and their banker, and consequently Bibi-Lupin’s antagonist. Thus, though placed in solitary confinement, he trusted to the intelligent and unreserved devotion of Asie, his right hand, and perhaps, too, to Paccard, his left hand, who, as he flattered himself, might return to his allegiance when once that thrifty subaltern had safely bestowed the seven hundred and fifty thousand francs that he had stolen. This was the reason why his attention had been so superhumanly alert all along the road. And, strange to say! his hopes were about to be amply fulfilled. The two solid side-walls of the archway were covered, to a height of six feet, with a permanent dado of mud formed of the splashes from the gutter; for, in those days, the foot passenger had no protection from the constant traffic of vehicles and from what was called the kicking of the carts, but curbstones placed upright at intervals, and much ground away by the naves of the wheels. More than once a heavy truck had crushed a heedless foot-passenger under that arch-way. Such indeed Paris remained in many districts and till long after. This circumstance may give some idea of the narrowness of the Saint-Jean gate and the ease with which it could be blocked. If a cab should be coming through from the Place de Greve while a costermonger-woman was pushing her little truck of apples in from the Rue du Martroi, a third vehicle of any kind produced difficulties. The foot-passengers fled in alarm, seeking a corner-stone to protect them from the old-fashioned axles, which had attained such prominence that a law was passed at last to reduce their length.
