William Hagan is Dublin's anonymous Bodyman who arrives on the scenes of sudden and violent deaths to bag and tag the corpses and remove them to the City Morgue for a post-mortem examination. It's a job he's been quietly doing for twenty years, content in the belief that he's performing a small but important function in the process of justice and a corporal work of mercy. When he turns up on a scene of death to find his daughter's corpse, all that changes. A year later, his wife has left him, and he lives in an empty house, sharing his life with the ghost of his daughter, Molly. There is a reason why Molly's soul is not moving on. The reported manner of her death as an accident is a lie. Hagan uncovers that she has been murdered and becomes a vigilante to find those responsible and punish them. His vast working knowledge of investigative procedures, pathology and murder enables him to deal with the guilty undetected.
