When a woman's mummified remains emerge from the water during a cave rescue operation, Dalziel and Pascoe embark upon a treacherous murder inquiry which rocks their world to its core.
Dalziel and Pascoe's investigation comes under increasing attack, despite their best efforts to search for clues. However, they battle harder than ever to uncover the truth about the mummified remains, which they believe are connected to the case of the Yorkshire chief constable's ex-wife, who vanished more than 20 years ago.
Dalziel and Pascoe continue their search for clues in the murder of a jockey and take little comfort from their rural surroundings as they find themselves getting dragged deeper into the dark side of horse racing.
