This is the third (of four) books by John Burns to feature his Crime Reporter, Max Chard. It follows the same format as the previous two in that Max fights a winning battle - so far - with his liver and the copious consumption of alcohol, something which seems to be de rigeur for all reporters, policemen and the occasional lawyer.
Whilst enjoying such activities, he manages to build a story around the nark of the title who, it seems, has grassed on her husband and the missing 5 million from a successful robbery. The husband has done a runner with both his share and his wife's, much to her disgust and so the 'nark' bit. Max and his monkey (photographer), Frankie Frost, are plunged into the covert life of undercover police hiding the aforesaid wife and her new lover whilst around her, members of the gang not banged up, are finding their lifespan curtailed abruptly. Indeed, Max is given a serious talking to by undesirables wishing to discover the whereabouts of the woman. He survives, of course, relishing momentarily his beating and gradually works out why the wife gave the police the information and just what happened to the husband.
I like these books. There's an old-fashioned humour about them, making me chuckle a time or two. Max has a good lifestyle, his girlfriend, Rosie, is a gem who understands him (not that this can be said of Max understanding Rosie), his colleagues at the Gazette are an electic bunch, each coping with the pressures of running a daily and put in the mix of the odd Plod or two and the scene is set for an amusing and highly readable tale. I'm into book 4 just now which I gather is the last of the lot, so boo hoo, tears aplenty.
