The pathologists must piece together the events at the scene of a raid on what was believed to be a terrorist cell. Several people were killed, including a policeman with the armed response team, and one of the alleged terrorists is in critical condition in hospital. The evidence raises many questions, not the least of which is the lack of weapons or bomb material in the flat. The evidence shows that the dead officer may have been killed by one of his own and suspicion falls on another member of the armed response unit who was having an affair with the dead man's wife. DI Adam Tranfield from the anti-terrorist unit puts pressure on Leo Dalton to hold back on his report. Nikki is attacked however and her laptop with the evidence is stolen.
