The new dark psychological thriller by acclaimed author D.L. Mark.

From the author of the bestselling DS McAvoy series, a dark, twisty thriller set in the Cambridgeshire countryside. Perfect for fans of Sharon Bolton, Emma Kavanagh and Ruth Ware.

She says he's a victim. They say he's a killer.

When Claudine witnesses an armed man murder several people in a suspected terrorist attack, she is horrified to discover one of the victims is her brother, Jethro.

Riven by grief, Claudine retreats to the family home in the Fens. She is left reeling when police tell her Jethro orchestrated the attack. Why would such a gentle, if troubled, man cause such bloodshed. and why include himself in the list of victims?

The answers could lie in his research into a mysterious cult, but as the police and Claudine both search for the truth, far darker secrets are revealed.

Claudine soon realises that if she can’t solve the mystery in time, more people will die. and the darkness will claim her too.

This twisty, unrelenting thriller, deftly exploring themes of grief and mental health, will leave you hooked and unsettled from the first page to the last.
