In 2010 he edited the First World War memoirs of pacifist saboteur Ronald Skirth, published as The Reluctant Tommy, and in 2014 his book Men of Letters: The Post Office Heroes Who Fought the Great War was nominated for the People's Book Prize.
Nuala Calvi also grew up in London, and trained as a journalist at London College of Printing. She has written for The Times, The Guardian, The Independent, the BBC and CNN, as well as numerous Time Out guides.
In 2012, Duncan and Nuala's book The Sugar Girls shot into the Sunday Times top-ten, spending eight weeks in the chart and finishing as the second highest history bestseller of the year.
