After a major accident leaves two dead, two critically wounded, and the surviving victims' lives changed forever, the father of one of the victims files a suit against the police department. Detective Inspector John Tolin must come to terms with his own past, and with his partner in the investigation if he has any hope of untangling the carnage, and understanding what caused the accident that threw so many lives together.

"At 5:57 on a Friday afternoon, a major incident took place on the A12: six cars were involved in a tragic collision that left two dead at the scene, two other critically wounded, and the surviving victims forever changed--their lives forever entwined. When the father of one of the victims files a suit against the police department for alleged complicity in the accident, Detective Inspector John Tolin ... just back from an extended leave, must come to terms with his own past--and with his partner in the investigation, Senior Investigating Officer Ann Stallwood ... --if he has any hope of untangling the carnage and understanding what caused the accident that threw so many lives together, for better or for worse. By focusing on ... how the individuals involved in the crash spent their days leading up to the crash, Tolin and Stallwood uncover much more than just the cause of the accident. Together, they must somehow find a way to continue their investigation once the suit against the Met is dropped, if they are to have any hope of solving crimes from smuggling to murder--even genocide."--
