A highly respectable middle-class married woman watches a window cleaner fill his bucket at her kitchen sink and has a sudden urge to rip off his shirt. They make love right there – the mad, bad, no-chance- to-breathe and when-can-we-do-it-next kind of sex. And both she and her windows end up with a special sparkle. then there is trouble. Big trouble. For this is an up-till-then contented doctor’s wife, a devoted mother with her own career as an optician. She doesn’t DO adultery, especially not with a working class bloke who drinks too much, thinks too little and has a wife and four children, one of whom is her daughter’s best pal.
