The book by Robert Louis Stevenson:
- Awesome Ego: Alan. As David says:For though [Alan] had a great taste for courage in other men, yet he admired it most in Alan Breck.
- First Installment Wins: How many people even know that there was a sequel, let alone have read it? Catriona is so obscure that when the 1971 film of Kidnapped adapted part of it, a few people thought that part was invented for the film.
- Ho Yay: Alan and David.
- Also doubles as a bit of No Yay, once you remember that David is 18 and Alan is about 35... almost twice his age. Also, historically, Alan was forty at the time.
- Moral Event Horizon: Uncle Ebenezer crosses it when he tries to kill David. Mr. Shuan crosses it when he kills Ransome.
- The Woobie: Ransome.
