Mrs St Clair was the wife of the businessman Neville St Clair. Her husband's business took him away from home frequently, and on one on his business trips he suddenly disappeared. The distraught Mrs St Clair enlisted Sherlock Holmes to find him, as she suspected he had been kidnapped since she believed she saw him some days later in an opium den in London. The resulting investigation was chronicled by John Watson in "The Man with the Twisted Lip".
