 Chauvelin's exact marital status, and whether or not he has other children, is unknown.His final brief appearance is in "The Triumph of the Scarlet Pimpernel", suggesting that, sometime between then and the events of "Mam'zelle Guillotine", he has been executed, presumably by the authorities after the Thermidorian Reaction.In "Lord Tony's Wife", it is implied that he survived until at least September 1794, since his testimony is said to have weighed heavily at the trial of Jean-Baptiste Carrier.
