The Associated Press reports that Walter Mosley, author of the Easy Rawlins detective novels as well as many other books, is being sued by his ex-wife for money she says he agreed to pay out of income from several of his books. Joy Kellman, married to Mosley from 1987 to 2001, says in court papers that Mosley owes her at least $500,000, plus interest, from earnings on 11 books as provided by their divorce agreement. Some of the books were published after their divorce.

Kellman’s court papers, filed Wednesday in Manhattan’s state Supreme Court, say Mosley failed to pay her 25% share of income from new editions or movie and TV versions of the books and from new formats such as audio books. Mosley also did not provide tax returns, royalty statements and other documentation about his income from 2001 through 2004, as required in the divorce agreement, until 2006, her court papers say, and much of the required information is still missing.
