The Susannah Ramsay and Sadie Dawes cases are solved and DCI Lesley Clarke's team is back together. But there are tensions. Is Dennis hiding more than just mental health problems? Did Superintendent Carpenter cover up the details of DCI Mackie's death? And does Lesley's girlfriend Elsa know more about Mackie than she's letting on? Just as Lesley feels she is getting closer to answers, she's forced to work on the other side of Dorset after a body is uncovered by a landslide at Lyme Regis's beach. Who is the body and is there a connection to DCI Mackie, Arthur Kelvin, and Elsa's law firm?
