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?

A tense and atmospheric police procedural from the author of the unforgettable Last Place You Look.

Praise for Under a Dark Cloud

'A great and unique locked room mystery that had me guessing all the way through to a fantastic ending. Under a Dark Cloud is full of drama, mystery and tension. One of my favourite series around.' James Delargy

'A coiled and wholly satisfying mystery, elevated by melancholic piquancy. The authentic police thrills and teasing dynamics of the characters are handled with the same elegance as the rueful climax, which long after the book is closed still feels perfect and inevitable.' Dominic Nolan

'Once again Louisa Scarr has created a thoroughly believable world in which to set a brilliantly compulsive story. The characters are so well-drawn that it's a pleasure to spend time with them, and I can't wait for number three!' Alison Belsham

'Characters I care about, inventive plot and expert storytelling a big thumbs up from me.' Fliss Chester

'A fast-paced and deft meteorological mystery that twists its way to a brilliant conclusion. Scarr's characters are beautifully realised, flawed and complex their stories make the quiet moments every bit as rewarding as the dramatic ones. If you haven't already read Butler & West, you're in for a treat' Heather Critchlow
