The Bookkeeper of Death: Henri Désiré Landru

In the spring of 1919, Detective Jules Belin knocked on the door of a Paris apartment and opened a trunk that would reveal the most meticulously documented killing operation in the history of European crime. Henri Désiré Landru, the Bluebeard of Gambais, had spent five years exploiting the catastrophic loneliness of wartime France, seducing vulnerable women through newspaper matrimonial advertisements, bringing them to isolated country villas, and incinerating their remains in a heavy kitchen stove. Eleven women were confirmed dead. Seventy-two more were never accounted for. He confessed to nothing.

The Bookkeeper of Death is the definitive narrative account of the Landru case: the crimes, the investigation, the trial of the century at Versailles in 1921, and the century of cultural afterlife that has made Landru one of the most analysed figures in the history of serial homicide. Drawing on the black notebooks, the railway ticket receipts, the forensic record, and the testimony of the families who refused to stop searching, Mícheál Ó Flaithearta reconstructs not merely the story of one extraordinary predator but the story of the social world that made him possible, a world of institutional failure, structural loneliness, and the enduri

Mícheál Ó Flaithearta is an Irish crime writer and former detective whose career in An Garda Síochána gave him an investigator's eye for the mechanics of predation, the failures of institutional protection, and the human realities that criminal case files can obscure as readily as they reveal. Born and raised in Ireland, he brings to his narrative nonfiction the dual perspective of the practitioner who has worked criminal cases from the inside and the historian who understands that the most important questions a case raises are rarely the ones the legal process was designed to answer.

His books range across the full landscape of crime and its social conditions, from the serial killers of twentieth-century Europe and America to the ancient and medieval histories of civilisations whose violent dimensions the standard accounts have underserved. In each project, his central concern is the same: to recover the human reality of events that documentation has reduced to evidence, and to place the individual case within the structural and social analysis that transforms a crime story into a social document.

Mícheál Ó Flaithearta lives in Ireland. The Bookkeeper of Death is his most sustained engagement with the case he regards as the founding document of the modern serial killer: the man who turned loneliness into a killing system and kept meticulous records of everything except the truth.
