Die Schokoladenschnüffler plot
Anyone who is related to an English aristocratic family must die. The Zurich canton police send their best men on a journey, so to speak. This is a slightly different gangster hunt: the two top cops Max Rüttli and Gaston bite into the heels of a British serial killer. The "Tigerclaw" mass murderer has struck at least four times. Now the unknown culprit is after the beautiful Diana. What at first sight has no real coherence, in the smallest detail, becomes a well-crafted murder plan to get hold of the immense fortune of an English noble family.
