When Juliet Doyle discovers a gun in her daughter's bedroom, she turns to old friend DCI Alan Banks for advice. But Banks is taking a much-needed holiday, and it's left to DI Annie Cabbot to deal with the removal of the firearm. No one can foresee the operation's disastrous consequences, or that the Doyles will not be the only family affected. Banks's daughter Tracy has fallen for the wrong boy. Her flatmate's boyfriend is good-looking, ambitious, and surrounded by an intoxicating air of mystery. He's also very dangerous. When Tracy warns him that the police might be on his tail, he persuades her to go on the run with him, and flattered by his attention, she agrees. Before she knows it, a deadly chase across the country is set in motion. And on his return, completely unsuspecting of Tracy's perilous situation, Banks is plunged into his most terrifying, personal case yet.
