In their anxiety to make themselves necessary, Peyrade, Corentin, and Contenson, at the Duke of Otranto’s instigation, had organized for the benefit of Louis XVIII. a sort of opposition police in which very capable agents were employed. Louis XVIII. died possessed of secrets which will remain secrets from the best informed historians. The struggle between the general police of the kingdom, and the King’s opposition police, led to many horrible disasters, of which a certain number of executions sealed the secrets. This is neither the place nor the occasion for entering into details on this subject, for these “Scenes of Paris Life” are not “Scenes of Political Life.” Enough has been said to show what were the means of living of the man who at the Cafe David was known as good old Canquoelle, and by what threads he was tied to the terrible and mysterious powers of the police. Between 1817 and 1822, Corentin, Contenson, Peyrade, and their myrmidons, were often required to keep watch over the Minister of Police himself. This perhaps explains why the Minister declined to employ Peyrade and Contenson, on whom Corentin contrived to cast the Minister’s suspicions, in order to be able to make use of his friend when his reinstatement was evidently out of the question. The Ministry put their faith in Corentin; they enjoined him to keep an eye on Peyrade, which amused Louis XVIII. Corentin and Peyrade were then masters of the position. Contenson, long attached to Peyrade, was still at his service. He had joined the force of the commercial police (the Gardes du Commerce) by his friend’s orders. And, in fact, as a result of the sort of zeal that is inspired by a profession we love, these two chiefs liked to place their best men in those posts where information was most likely to flow in. And, indeed, Contenson’s vices and dissipated habits, which had dragged him lower than his two friends, consumed so much money, that he needed a great deal of business.
