The House at Riverton is the first novel by the Australian author Kate Morton, published in the United Kingdom by Pan Macmillan in June 2007.
Contacted by the director, Ursula, as the only surviving person from that night, Grace decides to make a tape for her grandson, Marcus, sharing her secret with him.
One Christmas, David brings home a school friend, Robbie Hunter, with whom eleven-year-old Emmeline is infatuated but fifteen-year-old Hannah is less impressed.
Nearly ten years later, after David has been killed in WWI, Robbie finds Hannah to return a book she had given her brother.
Hannah is living in London and unhappily married to an older businessman, and Robbie provides a glimpse of the life she wanted to have.
The police find no suspicious circumstances and Emmeline returns to London, continuing to enjoy the high life until she is killed in a car accident.
Having carried this guilt her entire life, and finally telling the truth via the tapes to her grandson, Grace is able to die in peace.
