A fantastic book of its time. I read it years ago, as a teenager, in an abridged form and thought it was great. This time I was not disappointed. Written from a fourteen-year-old's viewpoint, this mystery of a strangler on the loose in a midlands town, has a dark message of 1960's Britain in decay: slum clearance, tower blocks, drug taking and even incest. Yet, unexpectedly, it always feels "cosy" and familiar. It was made into a film, starring Jenny Agutter, which has been much underrated.
