A Scandal in Bohemia : Sherlock Holmes

The King of Bohemia engages Holmes to recover an indiscreet photograph showing him with the renowned beauty, adventuress and opera singer Irene Adler – the revelation of which would derail his marriage to a daughter of the King of Scandinavia. In disguise, Holmes witnesses Adler marry the man she truly loves, then by means of an elaborate stratagem discovers the photograph's hiding place. But when Holmes and the king return to retrieve the photo, they find Adler has fled the country with it, leaving behind a letter for Holmes and a portrait of herself for the King. The king allows Holmes to retain the portrait as a souvenir.
