Summary Something arouses Dietmar Ohlsen's suspicions: the new neighbors have bought the house without viewing it and the husband is out for hours at night. Ohlsen is a policeman, but he is retired. But that doesn't stop him from getting to the bottom of the matter - and doing so meticulously: observation, pursuit, an investigation board with photos and lots of notes in his little book suggest a new life's work. Much to the chagrin of his wife Helga, who had been looking forward to other times. Because of a hit-and-run, Ohlsen himself becomes the target of investigators Harry Mller and Nils Sanchez. The two find out that Ohlsen's suspicions are not unfounded, but that he himself has gone way too far. Ohlsen also realizes this when his Helga is suddenly in mortal danger. Mrs. Køppers also suggests retirement to the guard Helmut Husmann, who is completely taken by surprise by this idea. As is his colleague Daniel Schirmer, who has grown fond of Helmut and is therefore trying to prevent him from leaving. But Helmut discovers unexpected possibilities for a new way of living and is increasingly becoming more comfortable with the idea of retirement.
