Whilst fibres under the nails of the latest victim provide a link the the St Jude's homeless hostel Lana is interviewed as a formality and states that Owen Hanmore was outside the tube station at the time of the first death and must thus be innocent. Clarissa, however, finds evidence of Lana's prints on the victim's phone and Lana and Hanmore are both increasingly under suspicion as they locate Lana's child and attempt to kidnap him. The child will provide a link to the murders whilst Nikki helps Luke to come to terms with his own past.
