This is the prequel to the DCI Ryan series. LJ Ross actually wrote this several years after she launched the series with Holy Island, Book 1 of the series. This book tells the story of the case and the horrific events that set the stage for Ryan being on Holy Island. I read it after finishing the first three books. I would actually recommend starting with it, but many others think it is better to read Holy Island first.
The story is set in Newcastle Upon Tyne and takes the user through many of the sites in this historic British city including its iconic bridges. It gives you the backstory on the key characters featured in the series and how their working and personal relationships developed.
I haven’t listened to it, but there is an Audible Original version of this book that has received really good reviews. it stars Tom Bateman (Murder on the Orient Express, Jekyll & Hyde, Snatched), Bertie Carvel (Doctor Foster, Les Misérables), Hermione Norris (Spooks, Cold Feet) and Kevin Whately (Lewis, Auf Wiedersehen, Pet).
