The stunning conclusion to Malcolm Mackay's lauded Glasgow Trilogy returns readers to the city's underworld: a place of dark motives, dangerous allegiances and sudden, tragic ends.

It begins with two deaths: a money-man and a police informant. Deaths that offer a unique opportunity to a man like Calum MacLean. A hit man who has finally had enough of killing.

Calum plans an unprecedented escape just as his employers need him the most. Glasgow's biggest criminal organizations are gearing up for a final, fatal confrontation.

The panic over Calum's abrupt disappearance may finally give Detective Michael Fisher the chance he need to close the case of a lifetime. But first, he must track down a man who has become a master of disappearance. A man who has staked his life on staying in the shadows.
