In A Presumption of Death, Jill Paton Walsh tells how World War II changed the lives of Peter, Harriet and their growing family. The story opens in 1940. Harriet Vane - now Lady Peter Wimsey - has taken her children to safety in the country. But the war has followed them: glamorous RAF pilots and even more glamorous land-girls scandalise the villagers; the blackout makes the night-time lanes as sinister as the back alleys of London. Then the village's first air raid practise ends with a very real body on the ground - not a war casualty but a case of plain, old-fashioned murder. And even before the second body is found, Lord Peter Wimsey and his brilliant wife are on their way to finding the killer.
