DEVIL IN A BLUE DRESS author Walter Mosley is being sued by his ex-wife, for a percentage of his book royalties. JOY KELLMAN, who divorced Mosley in 2001 after 14 years of marriage, claims the writer owes her over $500,000 (GBP256,000) plus interest, from his earnings from 11 of his books, which was stipulated in their divorce agreement. Kellman filed court papers in Manhattan's Supreme Court on Wednesday (28MAR07), claiming Mosley renegated on an agreement to pay 25 per cent of his income from film or TV adaptations of his novels or audio versions of the books.
