In \"Kidnapped\" (1886) and later fiction such as \"The Master of Ballantrae\" (1888), Stevenson examined some of the extreme and contrary currents of Scotland\'s past, often projecting a dualism of both personality and belief. This dualism is most famous in \"Kidnapped\", whose two central characters are David Balfour, a Lowland Whig, and Alan Breck Stewart, a Highland Jacobite. The novel revolves around their friendship and their differences, suggesting a metaphor for Scotland itself. Stevenson wrote the sequel \"Catriona\" with the title David Balfour, but during serialisation in England the public became confused, thinking it might be a reprint of \"Kidnapped\". At publisher Cassell\'s request, the title was changed to \"Catriona\", after Balfour\'s daughter.
