I re-read this after many years and it still makes me feel hollow. Van Der Valk is bored. A young man is hired by a jewelry /antique boutique by chance. Something doesn‘t seem right so he goes to the police for advice and help. It‘s not a case, no overt crime,but Van Der Valk is curious as a cat, and begins to investigate on his own; all quite unofficial. It goes all wrong, and it is devastating.
