After fourteen years in prison, Leonard March is released early because he testifies against his former boss, Salvatore Lombard, in a deal with the prosecutor. When the press catches wind that March himself has carried out 28 contract killings, the situation becomes precarious: relatives of the victims threaten him, and it’s only a matter of time before his ex-boss's henchmen seek revenge. Until then, March resigns himself to his new, dreary existence as a janitor, an old, lonely man waiting for death. That is until the attractive Sophie appears, introducing herself as a ghostwriter for his biography. With literary finesse, Zeltserman crafts a brilliant character study of a man, once a top killer of the Boston Mafia, on a quest for self-discovery.
