The Angel of Blissful Death

Czechoslovak counter-espionage intercepts a coded message from the West German secret service ordering death for an unknown person on Czech territory. Among the unusual deaths that follow in the course of the next few hours, a car mechanic and his girlfriend die in a car whose brakes were apparently damaged. The car belonged to a foreign citizen named Mertens and the car mechanic borrowed it without permission. Mertens is subsequently found dead in his room in a Brno hotel. He was electrocuted by his electric razor, which had been tampered with. The investigators believe a woman agent was involved and reveal that Mertens was in contact with a prostitute nicknamed Show Rose [Šaurůža]; she, however, has nothing to do with the case. The painstaking investigation leads the counter-espionage agents to Věra Weimannová and engineer Radek. The current piece of espionage turns out to be connected to a twenty-year-old unsolved case. Mertens was a spy. His stand-in is arrested on the border and a member of Czechoslovak counter-espionage is substituted. The investigators thus manage to discover the identity of Merten's murderer - the taxi driver Burda. Both he and Radek were personally interested in preventing Mertens from finding what he was searching for - a secret Nazi archive buried in a Moravian cemetery. When the particular cemetery is identified from an old photograph, it comes out that it had been flooded when a new dam was built. Burda, Radek and Weimannová are arrested.
