In Western Australia, Sarah chuckles as she describes her final will and testament - which will throw the metaphorical cat among the family pigeons - whilst sharing a bottle of wine with her neighbour Thomas as they sit on the terrace of her luxurious waterside home. Six months later, at the age of ninety-five, she peacefully passes on. Married and widowed three times, Sarah has had a great life as a successful businesswoman. Now she's left her Australian house to her two great-nieces - on the condition that they live in it together for a year. After that, they can sell it and split the money between them. If either of them doesn't last all twelve months, the next person on the list will be invited to try for the inheritance - but will still have to stick it out a full year before the house can be sold . . .
