DCI Thatcher solves murders for a reason. He's not the guy you call to solve a robbery. But when the robbery is at the house of an important councilman, the department needs to bring in the best. And Thatcher's the best.
But Thatcher might also be too close to the case. As he and Mills dig deeper into the crime, their prime suspect is Archie Gray. Who happens to be Jeannie Gray's brother. And Jeannie Gray happens to be Thatcher's old flame.
The case soon takes a turn into Thatcher and Mills's department when the injured housekeeper is murdered in her hospital bed. Thatcher has to keep his personal feelings at bay and follow the evidence at the risk of his career and the wrath of the department head. But the one thing Thatcher can't live with is putting an innocent man behind bars.
