Holmes and Dr. Watson take on the case of a beautiful woman whose husband has vanished. The investigation proves strange indeed, involving six missing midgets, villainous monks, a Scottish castle, the Loch Ness monster, and covert naval experiments.
Unfortunately the movie The Private Life of Sherlock Holmes is not yet available on HBO Max.
