Hungry Ghost - Stephen Leather

Hong Kong, 1991. The colony prepares for Chinese rule.

Geoff Howells, a government-trained killing machine, is brought out of retirement and sent to Hong Kong. His brief: to assassinate Chinese Mafia leader, Simon Ng. Howells devises a dangerous and complicated plan to reach his intended victim - only to find himself the next target.

Patrick Dugan, a Hong Kong policeman, has been held back in his career because of his connections - his sister is married to Simon Ng. But when Ng's daughter is kidnapped and Ng himself disappears, Dugan gets caught up in a series of violent events and an international network on spies that have run out of control.
