The novel “Malpertuis” by Jean Ray was published for the first time in 1943 in French. In time it was translated into a number of languages.

Jean-Jacques Grandsire is just a boy when his great-uncle Quentin Moretus Cassave dies. His testament is read in circumstances that are already quite strange and Cassave’s last will impose his heirs to live in the Malpertuis mansion. Since the deceased turned out to be even richer than expected, the heirs agree.

Soon, in Malpertuis strange things start happening. Events that seem supernatural suggest that the house is in some way haunted. Among the inhabitants someone knows more than the others because not everybody is exactly what they appear but what secrets are concealed in Malpertuis?
