"After a body is found in a canal, tied up in a sleeping bag and weighed down with bricks, DC Sean Blake is sent in to investigate. Another body with links to the first is soon discovered under similar circumstances, meaning a clear pattern is emerging and a mysterious figure seen asking questions about the victims becomes the prime suspect. But as Blake delves into the pasts of those killed and their friends still living - including one who is now the crime lord of Manchester - their group's transgressions as teenagers come to light and, with them, more suspects. Matters are complicated for Blake when those in the group refuse to cooperate with the police. With a killer so determined and targets unwilling to accept help, can Blake track down the correct suspect before each of them are eliminated?"--Publisher.
