I Natt är du död - 2

Thomas and Mia continue their investigation. Marcus Nielsen, who studied psychology, had scheduled several meetings with former Marine Commandos. He wanted to talk about group psychology and their time in the special forces. The trail of clues leads to Korsö, a military camp outside of Sandhamn, where the Marine Commandos used to be based. Thomas and Mia try to track down the group. More and more information surfaces about how tough things were at Korsö. They interview an officer, Cronwall, who has a hard time remembering and denies meeting Marcus.
