The Bulgari Connection

Blurb

The Bulgari Connection is a 2001 novel by Fay Weldon that became notorious for its commercial tie-in: in exchange for £18,000 from the jeweler Bulgari, Weldon was required to mention the name of the jeweler at least 12 times - which was more than exceeded by the author. The 34 mentions appear in sentences such as "'A Bulgari necklace in the hand is worth two in the bush', said Doris" or "They snuggled together happily for a bit, all passion spent; and she met him at Bulgari that lunchtime". Such heavy use of product placement was not only a novelty in literature but also unprecedented for a published, established author, and a front-page article was published about it in the New York Times, quoting such writers as Rick Moody, J. G. Ballard, Michael Chabon, and Jeanette Winterson.
The story concerns a character named Grace McNab Salt, and her re-integration into high society after ending a term in prison that she served for attempting to run her husband's mistress Doris Dubois over with her car.
