Greenshore House

In the novella Hercule Poirot and the Greenshore Folly, Greenshore House is a country house near the town of Lapton in Devon and the location where most of the events in the story takes place. When the novella was expanded later to become Dead Man's Folly, Greenshore House become Nasse House.

Like Nasse House, Greenshore House was based on Agatha Christie's own holiday home Greenway. According to John Curran, the descriptions of Greenshore House (a "foursquare no-nonsense Georgian House") and other architectural features of the estate all match Greenway very closely. Like Greenway, Greenshore has a lodge, Ferry Cottage, a battery, a tennis court, a boathouse and a youth hostel nearby. The internal geography also matches closely, including "the drawing-room with its French window, the room across the hall lined with bookshelves' with a 'table by the window', and Poirot's bedroom - 'along a passage to a big airy room looking out over the river' - with the bathroom across the corridor. The magnolia tree near the front door where Mrs Folliat and Hattie stand to talk, the drive ending at the big iron gates, the winding and steep path connecting the Battery and the Boathouse - all these exist in reality and can be seen and enjoyed by present-day visitors to Greenway House...."
