Story : Boulton and Stanton's personal affairs threaten to get in the way of their investigation, as Stanton attempts to block out the events of the night before. Persuading Meadows to separate the two investigations, Holmes discovers another link in the cases in a second witness who is involved with both victims. However, refusing to have her statement recorded on tape, Boulton is forced to use the information to place a 'bomb' underneath the Carter family, hoping it will go off and that they will all implicate themselves in the separate crimes they have committed. Stanton tries to distance herself from a smitten Boulton, who is unaware that the "sick mother" she keeps visiting is actually CIB's Detective Superintendent Steve Hodges.
