This story focuses on a well-known theme: the danger of making a pact with the Devil.
In this story, a Hawaiian man called Keawe purchases a bottle in which resides a tiny imp. The imp is capable of granting any wish, but the cost of owning such a powerful object is very high, as Keawe finds, to his cost. Stevenson has given this age-old theme a fascinating twist, making this a compelling and disturbing tale.
