Billionaire Walter Richman has built himself his dream home - the Observatory, a mansion like no other mansion - at the foot of the world's highest mountain in the cold Antarctic waters south of Tasmania.
Living a far humbler life is Rita Gausse, estranged daughter of the architect who designed the Observatory. Rita is surprised, upon her father's death, to be invited to the Observatory to meet the famous Richman in person.
From the beginning, something doesn't feel right. Why is Richman so insistent that she come? What does he, and the additional guests he has invited, expect of her?
When cataclysmic circumstances intervene to trap Rita and the others in the Observatory, cut off from the outside world, she slowly begins to learn the unsettling - and ultimately horrifying - answers.
The Rich Man's House, Andrew McGahan's eleventh and final novel, is a gripping and unique thriller.
