Nouveau-riche Napoléon Verdinage acquires Marchenoire Manor despite mysterious missives warning him against purchasing this “forbiddin [sic] house” and promising his untimely demise. Learning that the previous owners either died or took the letter writer’s warnings to heart and left, Verdinage becomes only more determined to stay. He only has himself to blame, then, when at the two month deadline given for his departure he is shot dead by a man who apparently vanished from the house…an outcome all the more baffling because the only exit was watched the entire time and multiple searches fail to discover the killer anywhere inside.
