Detective Liam O'Reilly is bored. Life on the peaceful island of Guernsey is quiet, but it's too quiet for his liking. In the middle of an insurance fraud investigation, he confides in his daughter and tells her he'd give anything for a juicy murder case to sink his teeth into. "Be careful what you wish for, Dad." Her words are still fresh in his mind when O'Reilly stumbles upon two dead bodies while investigating a fire at a container depot. The bodies have been burned beyond recognition. Soon it becomes very clear that something sinister is happening on the sleepy island.

Detective Inspector Liam O'Reilly has recently transferred to the island of Guernsey from the Special Detective Unit in Dublin, and in this first installment, we see him hitting the ground running. He has barely set foot on the island when the body of a man is washed up on the shore.
