Jack attends the funeral of ex-cop Derek Brooker who went to his grave trying to prove that journalist Peter Edelmann was killed by the American Air Force to stop him exposing an alleged U.F.O. crash, and persuades Sandra to re-open the case. The former Air Base Colonel denies that Peter was ever there, claiming he committed suicide, but local ufologists say that they were present with him and a code, encrypted in a lottery ticket, unlocks his findings. It was a plane crash, the corpses all suspected terrorists illegally abducted by the American government. However the ufologists and another eye-witness, an ex-airman whose café has been set alight by persons unknown, are too frightened to testify and the case remains officially unsolved.
