An audio book.
Antonia (first person PoV, daughter of a poor parson - a sheltered upbringing) met Hugh (son of an Earl) at St Andrews university, was pregnant in her final year, married and moved to Sydney. After 10 years Hugh tells her he's moving out to live with Greg, a hairdresser used by her friends. She's nearly molested by Dave, the husband of Nicki, a friend, at a party. Rumours start about her being a desperate flirt.
Percy, an extravagently gay relative of Hugh, turns up and lives with her.
She's started a shop called "Anteeks". She renovates old things. Nicki starts a similar shop and it flops. Dee helps her and becomes a de facto business partner.
She (suddenly!) realises she's fat and joins a gym, meeting James there, a private eye. Having been celibate for a year she starts having sex with him without knowing where he lives. He invites her to a stake-out. Some people want an old, haunted building to be knocked down to build a shopping centre. For some reason the 4 main people interested in the plan decide they need to visit the place at night. They see James's car and approach. Antonia thinks that having oral sex in the car will stop them being curious. She's right - they don't even note the registration number. Nikki's and Dee's husbands are there.
She invites James to a meal, inviting Hugh and Greg too. Greg and Tom get on well. Hugh is rude and James, aware of the class difference, calls off the affair. Then he changes his mind and invites her to a pool club/pub. James's ex, Jasmine, is there.
Dee disappears. So does James. Heavies working for Dee's husband have busted his knees. The heavies then the police visit her shop. He tells her he was in prison for a while - an eco-warrier. Percy tells her that he was once in love - with a working class fellow student at Oxford. That's why he's against snobbery.
The wives – Dee etc - are hiding away. They used to be whores. When each moved to the city, rich old men competed to be the first to have sex with them. Sometimes they married their clients. The police apprehend the culprits. James and Antonia marry and have a baby.
Low octave. My favourite phrase was “with all the confidence of a 7 year old who has just learnt a new fact.” Male sex organ size is of prime interest to the gay characters, and becomes a theme even Tom picks up.
