The author of the “diabolically clever”* A Matter of Blood returns with another gritty supernatural thriller featuring hard-boiled homicide detective Cass Jones…

A devastating terrorist attack has crippled London. To find a perpetrator who is more than human, Special Branch turns to Detective Inspector Cass Jones.

Cass is already investigating a series of student suicides, but saying no to Special Branch isn’t an option—even when he’s hit with a much more personal and deeply disturbing mystery: a message left for him by his murdered brother revealing that Cass’s nephew was stolen at birth.
