‘I hate being famous!’ Kate Kennedy confessed as she sat on the floor of her sister Anne’s flat. They were sharing a takeaway with a large Burmese cat called Carl Gustav Jung.

When her biography of Jane Austen was published Kate had found herself a celebrity overnight. She was invited onto talk shows, she was interviewed by three national daily newspapers and two Sundays, she toured the libraries and bookshops of Britain and she met Jon Bevan, described by the Guardian as one of England’s most brilliant young literary novelists and poets. The reason for all this interest? What the Times Literary Supplement called her ‘sizzling exposé’ of Jane’s hidden sensuality; her repressed sexuality; the passion in those well-loved, measured paragraphs.

Three weeks after meeting Jon she moved into his Kensington flat and her life changed forever.

Her elder sister and former flatmate, Anne, had remained philosophical about being deserted. (‘My dear, it was bound to happen to one of us sooner or later.’) Herself a writer – a Jungian psychologist whose library, especially the Freudian bits, Kate had ransacked when writing Jane – she had watched with amusement as Kate coped with fame. And found it wanting.

‘If you hate it so much, bow out. Become a recluse. Decline to appear, my dear. Cultivate a certain boorishness. And wear a veil.’ Anne licked soy sauce off her fingers. ‘Your sales would double overnight.’

‘Cynic.’ Kate smiled at her fondly. ‘Jon says I’m mad. He loves it, of course.’

‘I can see Jon giving up writing in the end to become a media person,’ Anne said thoughtfully. She wiped her hands on a paper napkin stamped with Chinese characters and, wrapping her arms around her legs, rested her chin thoughtfully on her knees. ‘He’s bad for you, you know, Kate. He’s a psychic vampire.’ She grinned. ‘He’s feeding off your creative energy.’
