Caro Ramsay writes Scottish police procedurals best known for the Anderson and Costello series. Absolution introduces Glasgow detectives Colin Anderson and Freddie Costello through a case involving an apparent serial killer and unresolved crimes, while Singing to the Dead, Dark Water and later novels continue with murders that often expose older family or institutional secrets. Ramsay uses an ensemble police cast rather than a single isolated genius detective, giving team relationships and recurring personal pressures space across the series. The tone is dark and procedural, with violence treated seriously rather than as cosy puzzle material. Her work fits Tartan noir, Glasgow crime and long-running police investigation series.
