Five-year-old Connor Reid is strangled and security cameras show the two little girls who baby-sit him, Paige and prostitute’s daughter Rose, take him into the empty flat where his corpse was found. In interview Paige breaks down and names Rose as the killer, though, in court, Rose’s brief Kim Sharkey invites the court to accept Paige as the guilty party and forensics seem to implicate her as the murderess. Then Alesha finds evidence to nail Rose as the killer and the prosecution, pleading the girl’s abusive upbringing as grounds for diminished responsibility, seek psychiatric care for her. However Sharkey, after professional glory, wants an all-or-nothing verdict. James puts Rose’s vile mother in the witness box to prove the prosecution point and save Rose from a murder charge.
