Sherlock Holmes and Dr John Watson are asked to investigate mysterious hauntings that are taking place at a waxworks museum.
The owner of the museum, Mr Chamberlain, has received reports of objects moving on their own, eerie sounds echoing through the walls, and ghostly figures moving through the many corridors of the old building. As the rumours increase, and his visitor numbers fall as a result, Mr Chamberlain asks Holmes and Watson to find out what, or who is causing the disturbances.
