 The main action of the book takes place in 'Peter's Room' - the loft of a disused outbuilding which Peter Marlow has been exploring, uncovering a variety of artefacts, such as a series of ancient farm record books.Snowed in at Trennels and spurred initially by Ginty's school project on the Brontë sisters' fantasy writings, they invent a swashbuckling story set in the imagined lands of Angora and Exina.The fantasy created by the four youngest Marlow children (twins Nicola and Lawrie, Ginty and Peter) and their friend Patrick Merrick, takes up three chapters of the book.
