Show Business Kills

The author of Beaches has recycled her bestselling blend of show business and devoted friends tested by tragedy into an involving story of contemporary Hollywood. Best friends since their college days 30 years past, soap opera seductress Jan O'Malley, former sitcom star Marly Bennett, Oscar-nominated screenwriter Rose Morris and studio executive Ellen Bass must face facts: they've now reached the age where their ``drug of choice has become estrogen.'' Confronted with her TV character's possible extinction, Jan is renegotiating her contract with barracuda-like producers, while Marly is auditioning for antacid commercials. Rose's agent wants to find her a ``young'' writing partner, and Ellen is fighting a losing war with a pack of sexually harassing studio honchos. When Jan is shot by a mysterious intruder, the other three investigate old lovers, old friends and old secrets until they discover her attacker's identity. Dart's snappily paced tale is spiced with spot-on doses of black humor, while her insights into female friendships, as always, ring reassuringly true. Even a cliched and familiar conclusion should do nothing to hinder fans' enjoyment. Film rights to Bette Midler's All Girl Productions; author tour. (Feb.)
