Pamela Flood's biggest fear was that her family history would be too normal and mundane... She needn't have worried. An innocuous letter written by her grandmother opens up an amazing adventure through 19th and early 20th Century Dublin, taking in grand gentry houses and red-light districts, millionaire solicitors and pawnbrokers, contested wills, illegitimate children and, eventually, murder. The only inkling Pamela had of something unusual in her family tree was a story her Granny used to tell, about being sent to stay with her grandmother at Corballis House: a grand country home that, until this year, stood at the entrance to Dublin Airport. How could such an ordinary, working class family be connected to such a posh house, and why did they leave?
