From the blast from the past pile, I remember reading this book when it first came out in 1991 so a reread to discuss here.
From the Blurb:
'You can never be too thin or too rich,' said Wallis Simpson, Duchess of WIndsor.
But Francesca Miles, independent feminist detective, disagrees. When one of the richest men in Sydney is found dead in his penthouse she teams up with Inspector Joe Barnaby in a mystery that follows the trials and tribulations of a family that should have everything money can buy.
