A daring daylight art theft from a crowded museum, a secret document centuries old, and a hidden treasure, these are the elements of the title story in this collection of tales by R. Austin Freeman. Though best known for his famous forensic sleuth, Dr. John Thorndyke, Freeman also on occasion wrote stories featuring other characters. In addition to "The Great Portrait Mystery," this collection features four more of these tales which show a more whimsical and humorous side of the author, dealing in turn with a bewitched curate, thieves whose clever plans go adrift, a haunted lawyer, and a poor bricklayer on whom fortune smiles in a strange fashion. In addition, two stories have been included featuring Dr. Thorndyke which were in the original 1918 edition of The Great Portrait Mystery, but have often been omitted from subsequent ones.
