London Falling by Paul Cornell is released on 18 July from Tor at £7.99:
“The dark is rising . . . 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.”
