Times have certainly changed for Moses Wine since the days of his first case in ''The Big Fix''-he''s gone from cheap detective to respected private investigator in just twenty-five years. Add in a beautiful girlfriend and a lucrative business with a roster of corporate clients, and he should be feeling on top of the world. But he''s not. In fact, he feels as though he''s lost touch with his roots, now ''living the kind or bourgeois live I once reviled,'' as he notes. Moses Wine of the sixties has been pushed aside by the lure of vacations at Lake Tahoe, expensive meals, and unlimited access to courtside seats at Los Angeles Lakers games. Now the shadow of Wine''s radical days has come back to haunt him. His college-age son, Simon, a radical environmentalist, has been accused of killing a logger in Northern California. Allying himself with his hostile ex-wife, Wine heads off to find the real killer whether it''s Simon or not! Laced with Roger L. Simon''s mordant wit, California politics and not-so-casual sex, ''The Lost Coast'' is vintage Wine at its best.Ever restless, ROGER L. SIMON has spent his life moving between books and movies, gaining distinction in both. In books, he is best known for the seven Moses Wine detective novels, which have won prizes in the U.S. and Great Britain and been published in over a dozen languages. In film, most prominent among his six produced screenplays-including his adaptation of The Big Fix-is Enemies, A Love Story, for which Simon was nominated for an Academy Award.
