McCroon breaks into Craven's house intent on killing him. Craven demands McCroon tell him who he is working for but McCroon is shot by a police marksman before he can say anything. Through a contact of Mac, a colleague from his time in Northern Ireland, Craven gains access to a terminal connected to the MI5 computer. He checks the MI5 records for GAIA, Northmoor and Emma and learns that McCroon was acting on the orders of Northmoor Security. He also obtains a three-dimensional map of Northmoor from the computer. Craven contacts Jedburgh and asks him to accompany him inside Northmoor.
