The King of the Rainy Country

This was the end of the story that had started 'Once upon a time, in a rainy country, there was a king…' The end had not happened in a rainy country, but on a bone-dry Spanish hillside, three hundred metres from where Van der Valk had left a lot of blood, some splintered bone, a few fragments of gut, and a ten-seventy-five Mauser rifle bullet.
No one had broken any laws. But a handsome, middle-aged millionaire had disappeared with a naked girl. And Van der Valk was given the job of finding out why.
