Since 2006, when Patricia Hughes first discovered the close resemblance of her father to William Butler Yeats, she has been researching and writing about what happened. Starting with a collection of her first research notes in 'William Butler Yeats and the Murder of Honor Bright', she progressed to An Analysis of Selected Poetry by William Butler Yeats between 1918 and 1928, before finally writng all her research findings into 'Who Killed Honor Bright? How William Butler and George Yeats Caused the Fall of the Irish Free State.' The essay in this book was a result of a talk she gave in 2015 at the University of Florence in Italy. It was published by Professor Fiorenzo Fantaccini of the Department of Irish Studies in the journal Studi Inglese'.
