Kaupunginpuistossa torvisoittokunta viritti soittimiaan, kolme soutuvenettä liukui järvellä, ruusutarha kukki täydessä loistossaan ja kahvilan terassilla tarjoiltiin limonadia varjossa. Vyvyan, pankkiiri, joka tunnettiin siitä, ettei koskaan antanut tippiä, oli istuutunut sanomalehtensä kanssa terassin pöydän ääreen. Kun soittokunta aloitti neljältä, hänet löydettiin lysähtäneenä tuon pöydän vierestä. Vain neljä ihmistä oli ollut hänen lähellään, ja jokainen antoi yhden lauseen lausunnon – selvitä, kuka oli yksin hänen kanssaan.","rules":{"standard":["Jokaisella <b>rivillä</b> ja jokaisessa <b>sarakkeessa</b> on täsmälleen <b>yksi henkilö</b>.
