The stories told and secrets kept in Ireland north and south are the focus of a pair of deeply personal new non fiction books - Missing Persons Or My Grandmother's Secrets from University of Cambridge Professor of English Literature Clair Wills and Dirty Linen by Martin Doyle who is Books Editor of the Irish Times. They're joined by the criminologist Dr Louise Brangan who researches the sociology of punishment, including work on Ireland's Magdalene Laundries and the poet Scott McKendry whose work deals with generational trauma and social decay in Belfast. John Gallagher hosts a discussion of how the stories we tell ourselves about ourselves and others can shape society and history itself.

Professor Clair Will's books include Lovers and Strangers: An Immigrant History of Post-War Britain and The Family Plot: Three Pieces on Containment.
