Then for the identity of the claimant with Anne Buirette there was seemingly conclusive evidence, the strongest part of it being her own statement of the date on which she was received at the Salpêtrière. All the story of her release through the appeal to the Duchess of Polignac was declared to be untrue. The past life of this Anne Buirette was raked up, and it was demonstrated that she was a swindler who had been sent to gaol for an ingenious fraud which may be narrated here. When in 1785, on the occasion of the birth of a royal prince, the queen wished charitably to redeem a number of the pledges in the Mont de Piété, the woman Buirette, being unauthorised, drove round in a carriage, calling herself a royal attendant, to collect pawn tickets from poor people. She recovered the sums necessary to redeem the pledges and applied the money to her own use. For this she was sent to the Salpêtrière, from which she was released in October, 1789, and not, as she stated, on the day of the barricades.
From this moment, according to the defence, the fraud began, whether at her own instance or not could not be shown. Her movements were traced from place to place as she went about seeking recognition and assistance, now accepted, more often rejected, by those to whom she appealed. Finally the commissary closed the case by pointing to the physical dissimilarity between the two women, the Marquise and the claimant. The first was known as a lady of quality, distinguished in her manners, clever, well-bred; the second was obviously stupid and low-born, stained with vices, given to drink. The Marquise was of frail, delicate constitution, the claimant seemed strong and robust; the first had blue eyes, the second black; the first walked lame, the second showed no signs of lameness.
Yet the claimant persisted, and her counsel upset much that had been urged. It was shown that the death certificate was not produced; that the ill-written letters so condemnatory were copies, not originals; that the official documents purporting to set forth the past life of Anne Buirette were irregular in form and probably not authentic. The claimant showed that she was lame, that her eyes were blue; more, that she carried the scar of the sword wound made by her mad husband years before. It was all to no purpose. The tribunal refused to enter into the question of the alleged falsity of the documentary evidence, and taking its stand upon the date of entry into the Salpêtrière, declared that the claimant could not be the Marquise de Douhault.
