When you're in love, the whole world speaks of your beloved. Certainly this is true for Inspector Van der Valk, though it takes some time for him to recognize the cause of his condition. The beloved in this instance is Lucienne Englebert, the beautiful, troubled daughter of a well-known conductor, now orphaned and running riot through Amsterdam. And calling Lucienne to mind is everything and everyone that Van der Valk encounters, from an embittered piano-dealer to an secluded fishing lodge, from a garrulous mechanic to an expensive, abandoned car. Clearly, all roads that Van der Valk is traveling lead back to Lucienne. But is love the only connection? Or could Lucienne possibly have something to do with the murder that Van der Valk is investigating?
