David Bowie once said about his former wife, Angie, that living with her "was like living with a blowtorch". After less than five minutes with her, I think I know what he means. She shouts, she rages, she looks like she might walk out of this suite we're sitting in at Claridge's at any second, and she seems happiest when she thinks I'm terrified of her. I'm not (well, not really, although she is a big woman - 55 years old, with bleached-blonde hair and pink lipstick, and nearly six foot in heels that she kicks off as she lies back on the sofa we share).
