From The Casebook of Sherlock Holmes: The Adventure of the Priory School & The Man with the Twisted Lip

Family problems complicate the case when Sherlock Holmes arrives at "The Priory School" to search for little Lord Saltire, son of the 7th Duke of Holdernesse. In "The Man with the Twisted Lip" Holmes and Dr. Watson comb the London waterfront looking for Neville St. Claire, finally confronting a horribly disfigured beggar who knows far more than he will say about the case.
