Episode 4

In the final episode, Tony tells Hannah she is in serious trouble as she protests that she does not know who the woman on the CCTV was but says has heard mention of a girl called Ruby. Hannah receives an anonymous email saying she can have the missing CCTV footage for £5,000. Simon traces the email to Louisa's office. Tony finds a distinctive man's overcoat at Louisa's office which he has seen on the CCTV footage and asks Geri if she ever used the name Ruby. She tells him to check the electoral register.
