He was never despondent save when he spoke of his profession. To all appearance he pined for the stage, and, in fact, he almost wept when he recalled the fantastic, many-colored costumes, clad in which he had once appeared before crowded audiences—audiences that had been convulsed with laughter by his sallies of wit, delivered between bursts of noisy music. He seemed to have become altogether a better fellow; more frank, communicative, and submissive. He eagerly embraced every opportunity to babble about his past, and over and over again did he recount the adventures of the roving life he had led while in the employ of M. Simpson, the showman. He had, of course, traveled a great deal; and he remembered everything he had seen; possessing, moreover, an inexhaustible fund of amusing stories, with which he entertained his custodians. His manner and his words were so natural that head keepers and subordinate turnkeys alike were quite willing to give credit to his assertions.

The governor of the Depot alone remained unconvinced. He had declared that this pretended buffoon must be some dangerous criminal who had escaped from Cayenne, and who for this reason was determined to conceal his antecedents. Such being this functionary’s opinion, he tried every means to substantiate it. Accordingly, during an entire fortnight, May was submitted to the scrutiny of innumerable members of the police force, to whom were added all the more notable private detectives of the capital. No one recognized him, however, and although his photograph was sent to all the prisons and police stations of the empire, not one of the officials could recognize his features.

Other circumstances occurred, each of which had its influence, and one and all of them speaking in the prisoner’s favor. For instance, the second bureau of the Prefecture de Police found positive traces of the existence of a strolling artist, named Tringlot, who was probably the man referred to in May’s story. This Tringlot had been dead several years. Then again, inquiries made in Germany revealed the fact that a certain M. Simpson was very well known in that country, where he had achieved great celebrity as a circus manager.

In presence of this information and the negative result of the scrutiny to which May had been subjected, the governor of the Depot abandoned his views and openly confessed that he had been mistaken. “The prisoner, May,” he wrote to the magistrate, “is really and truly what he pretends to be. There can be no further doubt on the subject.” This message, it may be added, was sent at Gevrol’s instigation.

So thus it was that M. Segmuller and Lecoq alone remained of their opinion. This opinion was at least worthy of consideration, as they alone knew all the details of the investigation which had been conducted with such strict secrecy; and yet this fact was of little import. It is not merely unpleasant, but often extremely dangerous to struggle on against all the world, and unfortunately for truth and logic one man’s opinion, correct though it may be, is nothing in the balance of daily life against the faulty views of a thousand adversaries.

The “May affair” had soon become notorious among the members of the police force; and whenever Lecoq appeared at the Prefecture he had to brave his colleagues’ sarcastic pleasantry. Nor did M. Segmuller escape scot free; for more than one fellow magistrate, meeting him on the stairs or in the corridor, inquired, with a smile, what he was doing with his Casper Hauser, his man in the Iron Mask, in a word, with his mysterious mountebank. When thus assailed, both M. Segmuller and Lecoq could scarcely restrain those movements of angry impatience which come naturally to a person who feels certain he is in the right and yet can not prove it.

“Ah, me!” sometimes exclaimed the magistrate, “why did D’Escorval break his leg? Had it not been for that cursed mishap, he would have been obliged to endure all these perplexities, and I—I should be enjoying myself like other people.”

“And I thought myself so shrewd!” murmured the young detective by his side.

Little by little anxiety did its work. Magistrate and detective both lost their appetites and looked haggard; and yet the idea of yielding never once occurred to them. Although of very different natures, they were both determined to persevere in the task they had set themselves—that of solving this tantalizing enigma. Lecoq, indeed, had resolved to renounce all other claims upon his time, and to devote himself entirely to the study of the case. “Henceforth,” he said to M. Segmuller, “I also will constitute myself a prisoner; and although the suspected murderer will be unable to see me, I shall not lose sight of him!”

It so happened that there was a loft between the cell occupied by May and the roof of the prison, a loft of such diminutive proportions that a man of average height could not stand upright in it. This loft had neither window nor skylight, and the gloom would have been intense, had not a few faint sun-rays struggled through the interstices of some ill-adjusted tiles. In this unattractive garret Lecoq established himself one fine morning, just at the hour when May was taking his daily walk in the courtyard of the prison accompanied by a couple of keepers. Under these circumstances there was no fear of Lecoq’s movements attracting the prisoner’s notice or suspicion. The garret had a paved floor, and first of all the young detective removed one of the stones with a pickax he had brought for the purpose. Beneath this stone he found a timber beam, through which he next proceeded to bore a hole of funnel shape, large at the top and gradually dwindling until on piercing the ceiling of the cell it was no more than two-thirds of an inch in diameter. Prior to commencing his operations, Lecoq had visited the prisoner’s quarters and had skilfully chosen the place of the projected aperture, so that the stains and graining of the beam would hide it from the view of any one below. He was yet at work when the governor of the Depot and his rival Gevrol appeared upon the threshold of the loft.
