聚光灯下的谋杀案

When the count Hervé de Kéraudren realizes that his days are numbered, he decides to hide in a secret alcove and die there, just to annoy his heirs. As a result of his body not being found, the heirs will have to wait for five years until they can inherit the count's money. This is a very upsetting situation, especially since they are required to keep up the Kéraudren estate in the meantime. To collect money, nephews and nieces organize a Son et Lumière show at the manor while busily looking for the missing corpse. But, unexpectedly, they get killed in turns. Murders or accidents? Jean-Marie, his fiancée Micheline, and his cousin Edwige investigate and finally succeed in exposing the culprit. And, the count's body being found by chance, all goes back to normal.
