DC Rachel Bailey interviews the mistress of a man who they suspect has murdered his wife and made it look like suicide.
The team face a particularly gruesome case involving a mother of two who has been brutally raped and left to bleed to death in the boot of her car.
A rape and murder case gets more complicated when only one of the alleged victims is prepared to testify.
Rachel and Janet are shocked by the revelations surrounding the case of a porn actress who is arrested on suspicion of murdering her husband.
Janet tells Geoff Hastings that they could be one step closer to bringing his sister's killer to justice after a current investigation provides similarities with Veronica's murder.
Rachel is narrowly missed by a car which smashes into the side of the road when she is walking home. The following day she finds she may have been targeted.
