Van der Valk

Officers investigating a hearse abandoned near the Royal Palace make a bizarre discovery which appears to be a threat against Paul Harkemer, well known editor of a right wing magazine, and/or his 19 year old daughter. At first it appears that it may be nothing more than a publicity stunt for the left wing rock band Emerald Scorpion, and Harkemer himself seems totally unconcerned. The case seems to over before it started, but then the police receive a cassette tape from someone claiming to be the kidnapper of Harkemer's daughter.
