One dead body. One witness. One answer.

Early one morning, DS Robin Butler is summoned to a crime scene. Not as a policeman, but as best friend to renowned meteorologist, Dr Finn Mason. The morning after studying an enormous storm, Finn has locked himself in a van. Bloodied, confused, and with no memory of how he came to be there. And alongside him – a dead body.

Butler sets out to prove Finn’s innocence, his friend now accused of murder. Meanwhile, DC Freya West is struggling to cope. She has been plagued by nightmares since the events of nine months ago. Freya assists her boss on his quest to clear Finn’s name, but while Butler becomes increasingly desperate to help his boyhood friend, Freya is crumbling under the weight of the secrets she is keeping.

As the past threatens to consume them both, do both detectives stand to lose more than they can bear?
