In Mad, Bad, Dangerous to Know Colm Tóibín turns his incisive gaze to three of Ireland's greatest writers, Oscar Wilde, W.B. Yeats and James Joyce, and their earliest influences: their fathers. From Wilde's doctor father, a brilliant statistician and amateur archaeologist, who was taken to court by an obsessed lover in a strange premonition of what would happen to his son; to Yeats' father, an impoverished artist and brilliant letter-writer who could never finish apainting; to John Stanislus Joyce, a singer, drinker and story-teller, a man unwilling to provide for his large family, whom his son James memorialised in his work.
