It begins with a phone call. Gordon Reeve's brother has been found dead in his car in San Diego. The car was locked from the inside, a gun was in his hand. In the US to identify the body Gordon realises that his brother has been murdered. What's more, it's soon obvious that his own life is in danger.
Once back in Scotland he finds out his home has been bugged by professionals. But Reeve is a professional too. Ex-SAS, he was half of a two-man unit with someone he came to fear, then to hate. It looks like his nemesis is back.
