Detective Inspector James Quill is about to complete the drugs bust of his career. Then his prize suspect Rob Toshack is murdered in custody. Furious, Quill pursues the investigation, co-opting intelligence analyst Lisa Ross and undercover cops Costain and Sefton. But nothing about Toshack’s murder is normal. Toshack had struck a bargain with a vindictive entity, whose occult powers kept Toshack one step ahead of the law – until his luck ran out.
Now, the team must find a 'suspect' who can bend space and time and alter memory itself. And they will kill again. As the group starts to see London’s sinister magic for themselves, they have two choices: panic or use their new abilities. Then they must hunt a terrifying supernatural force the only way they know how: using police methods, equipment and tactics. But they must all learn the rules of this new game - and quickly. More than their lives will depend on it.
