One of British crime writing's hidden jewels' Time Out At 19 years old Denise Prior knew little about criminals and even less about the law. In hindsight only her innocence was to blame for her affair with Detective Inspector Colin Harpur. That same innocence led to a friendship with ballet student Helen Surtees - live-in lover of Harpur's number one informer, Jack Lamb. It wasn't until later that the guns came out for the raid on the Link Street sub-post office. The tip-off had come from Jack Lamb and Harpur wanted to be there . . . but the Link Street shoot out changed everything, and Harpur's actions made Denise the only possible victim for a cruel and terrible revenge.
