Thorne and the team think they have a serial killer on their hands when a series of dead girls are discovered across east London.
After the attack on Thorne and the killer's letter, which puts Thorne right in the middle of the investigation, Brigstocke decides to replace him with his rival, Kevin Tughan.
Tughan discovers a photo of Phil Hendricks at the killer's lair, which firmly puts the pathologist in the frame as the killer.
