Book excerpt: This new and revised edition of Hilary Macaskill's classic book, with many new illustrations, offers an insight into the life and work of the world's bestselling author. Hilary Macaskill examines the houses that meant most to Agatha Christie, including her childhood home, Ashfield, in Torquay; Winterbrook in Oxfordshire, and, above all, Greenway, soaring above the River Dart and Agatha's favorite home from 1938 to the end of her life in 1976 (though requisitioned in the Second World War by the Admiralty, and from 1943 to 1945 home also to the United States Coast Guard). The author also explores more temporary abodes, not only a succession of flats and houses in London (mainly in Kensington and Chelsea) but also the homes she set up at the digs (mostly in the Middle East) that she traveled to with her archaeologist husband, Max Mallowan, and the hotels - notably the Moorland Hotel on Dartmoor, to which she adjourned in the grip of writer's block to complete her first detective novel, The Mysterious Affair at Styles, and the Burgh Island Hotel, a major inspiration for And Then There Were None and Evil Under the Sun.
