From the moment when he was left alone, apparently forgotten, in the insecurely locked compartment, until he opened the door and glanced around him, sufficient time had elapsed for a man of his intellect and discernment to analyze and calculate all the chances of so grave a step. Hence, if he had stepped into the snare laid for him, it must be with a full knowledge of the risks he had to run. He and Lecoq were alone together, free in the streets of Paris, armed with mutual distrust, equally obliged to resort to strategy, and forced to hide from each other. Lecoq, it is true, had an auxiliary--Father Absinthe. But who could say that May would not be aided by his redoubtable accomplice? Hence, it was a veritable duel, the result of which depended entirely upon the courage, skill, and coolness of the antagonists. All these thoughts flashed through the young detective’s brain with the quickness of lightning. Throwing down his spade, and running toward a sergeant de ville, who was just coming out of the Palais de Justice, he gave him a letter which was ready in his pocket. “Take this to M. Segmuller at once; it is a matter of importance,” said he. The policeman attempted to question this “loafer” who was in correspondence with the magistrates; but Lecoq had already darted off on the prisoner’s trail. May had covered but a short distance. He was sauntering along with his hands in his pockets; his head high in the air, his manner composed and full of assurance. Had he reflected that it would be dangerous to run while so near the prison from which he had just escaped? Or was he of opinion that as an opportunity of flight had been willingly furnished him, there was no danger of immediate rearrest? This was a point Lecoq could not decide. At all events, May showed no signs of quickening his pace even after crossing the bridge; and it was with the same tranquil manner that he next crossed the Quai aux Fleurs and turned into the Rue de la Cite. Nothing in his bearing or appearance proclaimed him to be an escaped prisoner. Since his trunk--that famous trunk which he pretended to have left at the Hotel de Mariembourg--had been returned to him, he had been well supplied with clothing: and he never failed, when summoned before the magistrate, to array himself in his best apparel. The garments he wore that day were black cloth, and their cut, combined with his manner, gave him the appearance of a working man of the better class taking a holiday. His tread, hitherto firm and decided, suddenly became uncertain when, after crossing the Seine, he reached the Rue St. Jacques. He walked more slowly, frequently hesitated, and glanced continually at the shops on either side of the way. “Evidently he is seeking something,” thought Lecoq: “but what?”
