If any man should be aware of the uses and sweets of friendship, is it not the moral leper known to the world as a spy, to the mob as a _mouchard_, to the department as an “agent”? Peyrade and Corentin were such friends as Orestes and Pylades. Peyrade had trained Corentin as Vien trained David; but the pupil soon surpassed his master. They had carried out more than one undertaking together. Peyrade, happy at having discerned Corentin’s superior abilities, had started him in his career by preparing a success for him. He obliged his disciple to make use of a mistress who had scorned him as a bait to catch a man (see _The Chouans_). And Corentin at that time was hardly five-and-twenty. Corentin, who had been retained as one of the generals of whom the Minister of Police is the High Constable, still held under the Duc de Rovigo the high position he had filled under the Duke of Otranto. Now at that time the general police and the criminal police were managed on similar principles. When any important business was on hand, an account was opened, as it were, for the three, four, five, really capable agents. The Minister, on being warned of some plot, by whatever means, would say to one of his colonels of the police force: “How much will you want to achieve this or that result?” Corentin or Contenson would go into the matter and reply: “Twenty, thirty, or forty thousand francs.” Then, as soon as the order was given to go ahead, all the means and the men were left to the judgment of Corentin or the agent selected. And the criminal police used to act in the same way to discover crimes with the famous Vidocq. Both branches of the police chose their men chiefly from among the ranks of well-known agents, who have matriculated in the business, and are, as it were, as soldiers of the secret army, so indispensable to a government, in spite of the public orations of philanthropists or narrow-minded moralists. But the absolute confidence placed in two men of the temper of Peyrade and Corentin conveyed to them the right of employing perfect strangers, under the risk, moreover, of being responsible to the Minister in all serious cases. Peyrade’s experience and acumen were too valuable to Corentin, who, after the storm of 1820 had blown over, employed his old friend, constantly consulted him, and contributed largely to his maintenance. Corentin managed to put about a thousand francs a month into Peyrade’s hands. Peyrade, on his part, did Corentin good service. In 1816 Corentin, on the strength of the discovery of the conspiracy in which the Bonapartist Gaudissart was implicated, tried to get Peyrade reinstated in his place in the police office; but some unknown influence was working against Peyrade. This was the reason why.
