The net is closing in on Alan Kennedy, the main suspect for the serial rapes. Kennedy is not at home when the police raid his flat, and several other leads - an allotment he keeps, and his (deceased) mother - also fall through. Eventually he is found through his hobby of falconry and arrested. CPS lawyer Jonathan Fox warns that more than the forensic evidence is needed to prosecute Kennedy, and reluctant witness Khadija Miah is brought into the station to identify him as her assailant. However, when Khadija runs into PC Gabriel Kent, PC Kerry Young could lose her job over the fact that she may have ""tainted"" the witness by showing her Gabriel's photograph. PC Cameron Tait's job is also on the line after his attack on Kent in the canteen. Despite Kent's agreement to a transfer, Tait decides to leave Sun Hill, London and Kerry Young behind and he catches a cab to Heathrow to fly back to Sydney.
