Sometimes helping a stranger is the last thing you should do . . . The Cornish village of St Petroc is the sort of place where people come to hide. Tom Killgannon is one such person. An ex-undercover cop, Tom is in the Witness Protection Programme hiding from some very violent people and St Petroc's offers him a chance to live a safe and quiet life. Until he meets Lila. Lila is a seventeen-year-old runaway. When she breaks into Tom's house she takes more than just his money. His wallet holds everything about his new identity. He also knows that Lila is in danger from the travellers' commune she's been living at. Something sinister has been going on there and Lila knows more than she realises. But to find her he risks not only giving away his location to the gangs he's in hiding from, but also becoming a target for whoever is hunting Lila.

Tom Killgannon, ex–undercover police officer and now in witness protection, is recalled to active service by a local police task force, headed by DS Sheridan. His mission is to befriend notorious child killer Noel Cunningham and find out where he buried the bodies of his final two victims. The catch? Tom has to obtain that information from within Blackmoor Prison itself. Undercover and with no backup, Tom soon runs into danger. In the prison is convicted gangster Dean Foley. He used to run Manchester’s biggest gang, until Tom’s testimony put him away for life. He recognizes Tom, and so begins a cat-and-mouse game as Tom fights for survival before Foley can get his revenge. But why can’t Tom reach DS Sheridan, and what is the real reason he has been sent to Blackmoor Prison?
