A cold treachery by Charles Todd

Set in 1919 Northern England, this historical mystery follows Inspector Ian Rutledge as he investigates the brutal mass murder of the Elcott family at a secluded farmhouse. Amidst a punishing winter storm, Rutledge must navigate the local community's insular nature while searching for a missing ten-year-old boy who witnessed the slaughter. The inspector is haunted by shell shock and the internal voice of a fallen soldier, adding a psychological layer to the hunt for the killer. Suspicion shifts between aggrieved relatives and outsiders, revealing deep-seated resentments and secrets buried within the valley. Ultimately, Rutledge must distinguish between the trauma of a frightened child and the calculated malice of a murderer to find justice.
