Another time, another life

When a Swedish civil servant is murdered, the two leading detectives on the case, Anna Holt and Bo Jarnebring, find their investigation hastily shelved by an incompetent and corrupt senior investigator. Ten years later, Lars Johansson, having just joined the Swedish Security Police, decides to tie up a few loose ends left behind by his predecessor: specifically, two files on Swedes who had allegedly collaborated on the 1975 takeover of the West German embassy.
