Self's Deception

Private investigator Gerhard Self receives a request to track down the daughter of Herr Salger, the Assistant Secretary of Bonn, who's been absent from her translation classes at the university. Repelled by the pomposity of the government official, Self rejects the case. But an insistent letter - and five thousand marks - changes his mind. After discreet interrogations and a quick survey of the local hospitals, it turns out she washed up at a psych ward where Self is told she had fallen out of a window earlier that week and died.

He quickly decides this is a lie and that one of the doctors is covering for her. Self soon discovers that his quarry was involved in a terrorist incident and is still alive - but it's an incident that the government is clearly covering up. Self helps the woman escape and finds out his own client is not Herr Salger at all but another terrorist. What exactly happened at the military arms depot that the government doesn't want made public?
