She lathered her own death into her hair.

Two hairdressers are dead. The latest, Gloria Baggot, was killed in the one place no one saw danger coming?the shower.

DI Liam McLaughlin and his Major Investigation Team can't find a clean link between the two women?no shared history, no shared enemies, no obvious motive. The only thing they had in common was their profession. And that alone is enough to spread terror through the city's salons.

As panic ripples across Derry, the investigation begins to shift. What first looked like coincidence starts to feel deliberate. Someone wanted Gloria dead. The question is why?and whether there's more to come.

The fourth in the NUMBER ONE bestselling Derry Murder Mysteries, Murder Rinse Repeat is a standalone, a razor-sharp, darkly comic thriller packed with shocking twists, relentless pacing, and Gerald Hansen's signature bite.
