 On 9 January 1836, Pierre Lacenaire goes to the guillotine, a murderer and a thief. He gives Allard, a police inspector, his life story, written while awaiting execution. He also asks Allard to care for Hermine, a lass to whom he has been guardian for more than ten years. In flashbacks, from the prison as Lacenaire writes, from Allard s study as he and Hermine read, and from other readers  memory after the book is published, we see Lacenaire s childhood as he stands up to bullies, including priests, his youthful thieving, his first murder, his brief army career, his seduction of a princess, and his affair with Avril, a young man who dies beside him.
