What came Before He Shot Her by Elizabeth George

I'm not much of a mystery reader but this book was recommended to me as having insight into why some people turn to crime. Joel Campbell is abandoned and abused from a very young age and still it is his essential goodness that puts him at risk in the mean neighborhood in London. In such a place, with such a life, the line between good and evil is blurry except in the eyes of the law. There is certainly much truth in this story - enough to make you marvel that anyone can break out of such a situation.
