The Sleeping Cardinal

First of five movies with Arthur Wontner as Sherlock Holmes. Card cheat Ronald Adair hears a disembodied voice coming from a painting of cardinal threatening him with exposure and disgrace unless he becomes part of a criminal conspiracy involving counterfeit money. Adair is reluctant and is later found shot in the head in a bank. Holmes rightly suspects that his arch-enemy Moriarity, the master of disguise, is behind the plot.
