Forensic experts Nikki and Jack return in this compelling crime drama, uncovering the truth behind suspicious deaths. There is change at the Lyell Centre with the sudden arrival of a new boss, pathologist and politically adroit Thomas Chamberlain. His new approach is met by a frosty reception and Chamberlain quickly recognises he will have to earn their trust if he is to make a success of his new appointment. As the team tackle the new dynamics, the cases keep coming; Nikki’s pursuit of the truth that frees a convicted killer; a trip to Scotland to investigate a violent death; and the hunt for a baby that ends with Jack’s confrontation of his troubled past.
