The Hound of the Baskervilles is a classic novel by Sir Arthur Conan Doyle, set in the English countryside of Devon and Dartmoor. The setting of the novel is the desolate and mysterious moorland, which is a large area of open, uncultivated land, often covered with heather and peat bogs. The two crossword solutions, MOOR (4 letters) and MOORS (5 letters), refer to this setting, as they are both words used to describe the wild and untamed landscape.
