But that is only the beginning of the puzzle. It starts on a sunny morning. A child delivers a death announcement to DeKok. "At the request of the deceased, no crocuses, or other flowers". DeKok and Vledder find a card under the windshield wiper of their car: "Ask for the naked lady..". Karate, divorces, sex theaters, crocuses and serial killings.
