This novel takes place over a year, a short while after the end of WW2, and begins very light-heartedly and comically with Penelope Stevenson, her brother Dick and her pregnant sister-in-law, Betty worrying about the guests they have coming -Lady Lupin and her husband, Andrew Hastings. Many jokes are had about the guests, with the usual stereotypes clouding their perceptions of them. However, this is soon debunked by the young and vivacious Lady Lupin, who quickly warms to Betty and Dick.
But when Dick and Betty find Penelope shot in the garden the question must be: was it suicide or murder?
