Please help me find the name of movie...
I saw the movie many years ago (20+)..it was a horror/thriller movie, but don't remember the title. There was a family, who lost in old castle, their old car was founded in the garden lake (old mercedes limousine...)... Their bodies were founded behind the secret door in fireplace in the castle...where was large room with other dead bodies...
This case was solved by some detective like Sherlock Holmes...but I am not sure.
Is there anybody who can tell me what movie it was? Many thanks...
Sorry for my english.
