Guy Mannering or The Astrologer is a novel by Sir Walter Scott, published anonymously in 1815. According to an introduction that Scott wrote in 1829, he had originally intended to write a story of the supernatural, but changed his mind soon after starting. The book was a huge success, the first edition selling out on the first day of publication. Guy Mannering is set in the 1760s to 1780s, mostly in the Galloway area of southwest Scotland, but with episodes in Cumberland, Holland, and India. It tells the story of Harry Bertram, the son of the Laird of Ellangowan, who is kidnapped at the age of five by smugglers after witnessing the murder of a customs officer. It follows the fortunes and adventures of Harry and his family in subsequent years, and the struggle over the inheritance of Ellangowan. The novel also depicts the lawlessness that existed at the time, when smugglers operated along the coast and thieves frequented the country roads.
