After a pearl with a sinister reputation for causing misfortune to its owners is stolen from a museum by a master criminal - because of Sherlock Holmes' show-boating - he is naturally obliged to find it. Soon, he learns of a series of brutal murders that seemed to have been committed by a malevolent man mountain known only as the Creeper. Now, Holmes must deal with the seemingly overwhelming menace of this man and his boss in order to retrieve the pearl.—Kenneth Chisholm
