Nemesis

They killed his sister. Now he'll kill them all.
Michael Bale is an elite close protection officer. That's why the Met police has given him the toughest job of all: guarding the Minister of Defence at a moment when Chinese-British relations have hit a deadly boiling point. And when Michael's life isn't on the line for his work, he's taking his chances waging war on a powerful London gang family. Their dealer supplied a lethal ecstasy pill to his sister, and Michael is determined to take them down, one at a time. But will he get away with it - or will his colleagues in the force realise that the man on an underworld killing spree is one of their own?
“Mickey Bale is a Jack Reacher for a harder, faster, more assured millennium. Nemesis is the kind of book for which the word 'compelling' was coined” MANDA SCOTT
