More unanswered questions. Is Lisa working for Hastings? Hastings spelt definitely wrong, as well as telling Lisa to bring it to a close. When she asked what he meant, Hastings said “You know what I mean” and disconnected the call. If Hastings is innocent, and I hope he is, then why didn’t he tell Steve and Kate about the money that he was given? Another edge of the chair ending. Excellent tv drama.
