The naked corpses of Aylmer and Mary Younis are discovered in their home. The only clues are a note written in blood and an eerie report of two spectral figures departing the crime scene. Officer Jill Ferriter is charged with investigating the murders while her colleague Alex Cupidi is on leave, recovering from post-traumatic stress.

The dead couple had made investments in a green reforestry scheme in Guatemala, resulting in the loss of all their savings. What is more disturbing is that Cupidi and Ferriter's disgraced former colleague and friend Bill South is also on the list of investors and the Younis's were not the only losers.

Despite being in counselling and receiving official warnings to stay away from police work Cupidi finds herself dragged into the case and begins to trawl among the secrets and lies that are held in the fishing community of Folkestone.

Desperate to exonerate South she finds herself murderously compromised when personal relationships cloud her judgement.
