The Monk With the Whip
Also known as Der Mönch mit der Peitsche, this is the story of German college girls getting murdered by someone other than a monk with a whip. Sure that monk is always lurking nearby but the actual killings are a convoluted scheme involving pickpockets, jailbreaks, and poison gas. I am beginning to realize that these late 60s Krimi aren’t terribly concerned with plot. As usual, the colorful style and comedic tone (and the casting of Slugworth) make it work despite this.
