MIT have a new suspect for the serial killings - Martin Porter, duty solicitor and former fiance of PC Kerry Young. Young and PC Ashton are kept in the dark about Porter's arrest, as they deal with a case of criminal damage in an off-licence perpetrated by none other than James Chandler. Thrown off-kilter by his brother's arrest, Supt. Tom Chandler blows a vital transfer interview at Scotland Yard, whilst DCI Meadows convinces James to make a statement accusing Chandler of raping Louise Marsden at Hendon. Chandler is rapidly running out of options, but he still has one card up his sleeve - his imminent marriage to Debbie McAllister. Insp. Gold fears a conflict of interest due to PC Cass Rickman's relationship with reporter Simon Kitson, and takes her off the case. Tension flares between Kitson and Nick Klein when Kitson interrupts a night out. DC Duncan Lennox attempts to get A/DI Nixon appointed to the MIT team as a profiler, but DCI Ross has other ideas.
