DCI Lesley Clarke is back in Dorset, and her world has turned upside down. One of the people she's closest to is to under arrest for the murder of DCI Mackie and a body has been found in the remote lighthouse at Portland Bill. And not just any body, but the body of someone she investigated before moving to Dorset. Can Lesley win the trust of the close-knit Portland community and find the killer? And can DI Zoe Finch of the West Midlands force help her track down potential suspects? Does Superintendent Carpenter know more than he's letting on about Mackie's death? And most importantly, can Lesley find her predecessor's real killer and ensure justice is done?
