Introducing Chris O'Brien, Private Investigator. Martial arts expert, Philosophy graduate, ex-psychiatric nurse and practitioner of Chinese medicine. Bradford's answer to Philip Marlowe. Nasty rumours circulating at Club Zed, one of Bradford's most popular nightclubs, lead to a call up for part-time bouncer and fledgling private eye, Chris O'Brien. Manager Tim Marconi has reason to believe that drugs are being dealt in his club, and that's made him mad. And that's not a good situation for anyone involved. O'Brien and his sidekick, the enthusiastic West Indian, Kelp start sniffing around for clues, confident that it shouldn't be too hard to flush out the culprits. But then the stakes are raised when a dead body turns up outside the club and the police swoop in. Soon Chris is involved in an investigation that will take him across the country and build up to a thrilling, violent and dirty confrontation that will require all his skill and cunning just to stay alive. That Which Doesn't Kill You is an action-packed, witty and sharply observed debut that marks the first appearance of Bradford's wise-cracking kung fu PI, Chris O'Brien.
