John Milton is the man the government call when they want a problem to vanish. But what happens when he's the one that needs to disappear?

After a botched job leaves a bloody trail, government assassin John Milton does the one thing he's never done before: he hides.

Disappearing into London's bustling East End and holing up in a vacant flat, Milton becomes involved with single mother Sharon and her troubled son Elijah, who are caught in an increasingly bloody turf war between two rival gangs.

Unable to ignore the threat, Milton sets about protecting mother and son, meeting violence with violence. But his involvement puts him in the sight of the government's next best killer, and before long Milton is not just fighting to save a family and a home - he's fighting to stay alive...

The Cleaner is the first tile in the John Milton series, and a UK Sunday Times Bestseller.
