Efter levande modell (1961)

Three young women and four young men are gathered in a hunting lodge on a small island. Two of the men, Paul and Bilbo, write a police drama for a big newspaper. Imprudently, they initially imagined a perfect crime, so perfect that they can not find the solution. And yet they worked "from nature": their novel takes place in a pavilion similar to that where they are and the characters are like them.
