Consider being commissioned and hard-pressed to write the biography of an old, famous, living author. Then imagine how much more difficult it would be if the manipulative subject wants the work to confirm his legacy and status; his young, controlling wife is trying to ensure an income after his death; and the publisher wants plenty of scandal in the book to ensure sales.
It is in this increasingly volatile vortex of competing agendas that British writer Harry Johnson finds himself after being given the task of living with and researching the life of Indian-born Mamoon Azam, a famed post-colonial novelist, essayist and interviewer whose sexuality and politics are convoluted.
Johnson's bullish and boozy publisher, Rob Deveraux, describes the relationship between Mamoon and his younger wife Liana "as if Gandhi had married Shirley Bassey and they'd gone to live in Ambridge".
If only it were that simple. In truth, their relationship is far more complex (author Kureishi seems to have had V.S. Naipaul in mind) and by being embedded with them Harry is drawn into a web of lies, deceit, mind games and sexual tension.
However, Johnson is hardly a sympathetic character so it is hard to empathise with his situation, especially when he starts a loveless affair with a young woman who works in the house while his partner is back in London.
As a book about writers, relationships and sexual politics, The Last Word is not without interest and the skilled Kureishi is quick to fill these pages with literary quips, bon mots and even more mal mots.
