I read Crack House in two sittings and it was a real eye-opener for me. I don't live in north London (thank God) and I was staggered to learn how many people are being killed and injured each year there and across the capital as a result of drugs. Harry Keeble tells the story of the months he spent as the head of the Haringey Drugs Squad, (sounds impressive, but actually just five or six coppers, an office in a Portakabin and a clapped out car). Heavily fortified crack houses are ruining the lives of hundreds of people in the borough and Keeble sets out to close 100 of them before he is moved on to his next job by the Met. This book is the story of how he went about doing this. It's a rattling good read, spoilt only by the revelation that the managers of the Metropolitan Police Force are just as cretinous as those in just about every other British public sector organisation. More power to the elbow of Mr Keeble and police officers like him.
