He played the same trick at Rochbeaucourt in the Dordogne. Now posing as the Comte de Gôlo he desired to purchase a chateau. Using the same methods as at Toulouse, he again made himself scarce with the moneys he borrowed. Then he appeared at Le Mans. He acquired property, and was on the point of exchanging land for diamonds at a jeweller’s, when the rumors of former fraud reached the place, and the police were set on his track. He was arrested, tried and convicted, and was sentenced to twenty years at the _bagne_, after exposure for an hour in the _carcan_, or iron collar, on the platform of the guillotine. He was sent first to Brest, but was transferred later to Rochefort, where he died in 1840, having endured his captivity with philosophy, and not, as has been said already, in extreme discomfort. “I have but one grief,” he said in the hospital of the _bagne_, “and that is that I am dying a _forçat_. My money is of no use to me;” for he undoubtedly possessed considerable funds, although the secret of their whereabouts was never disclosed. Collet had no small opinion of himself, and claimed to be an interesting criminal. His head was turned by the attention he attracted, and he actually replied in an open letter to the charges brought against him in the numerous biographies of him published in his lifetime. He sought to correct the severity of the criticisms passed upon him, and protested that the standard of his morality was put too low. “My life has had two sides,” he represented; “and, I am free to confess, presents features I cannot defend; on the other side I can point to many good deeds. I have given largely to the poor when I was in funds, and my conduct in prison has always been irreproachable.”
