DI Clare Mackay is about to face a test of her loyalty... When a report comes in that a van containing two prison officers and a convicted jewel thief is missing, the police in St Andrews work quickly to locate the vehicle. Their efforts prove in vain when no trace is found and they realise the wives of both officers also appear to have left the area. Is this a case of corrupt guards springing a felon, or innocent people caught in the crossfire? DI Clare Mackay leads the team but has to do without her right hand man; DS Chris West is a cousin to one of the missing prison officers and must not be involved in the case. With a new sergeant at her side plus a previously unencountered DCI, Clare's people skills are pushed to the limit. Especially once she realises her boss is keeping her on the sidelines. Just what is it that Clare doesn't know? And if she has to choose between keeping secrets from a friend, or letting slip something that could see a culprit go free, which path will she take? A compelling addition to the best selling series by a much-loved Scottish crime author, perfect for fans of Caro Ramsay, Lin Anderson and Alex Gray.
