The Picts and the Martyrs is the eleventh book in Arthur Ransome's Swallows and Amazons series of children's books. It was published in 1943 and set in early August 1932, at the very beginning of the summer holidays. This is the last completed book set at The Lake and features the Blackett sisters, the Amazons and the Callum siblings, the Ds. Ransome's most native character, the Great Aunt also features prominently as do many aspects of Lakeland life. The Dog's Home is based on a small stone hut built in the woods above Coniston Water close to Ransome's then residence.
