Literary agent Charlie Greene (Murder at Moot Point) arrives at her Beverly Hills office just in time to find receptionist Gloria Tuschman missing and to hear her disembodied voice whispering, ``Charlie, I'm in the trash can. Help me.'' Though Gloria's body is actually discovered in the bushes outside the office building, Charlie wonders whether she can use her newfound psychic powers, honed by a sÇance held by Gloria's real-life witches' coven, to figure out which of Gloria's blackmail victims in the office would kill to safeguard a guilty secret (exposure to AIDS, a prison record, a secret wife)--and what Gloria's death has to do with the disappearance of prickly novelist Mary Ann Leffler. Notable for its large, attractive cast, its shameless use of coincidence--you'll need to be psychic to tell which leads mean anything--and the breathtaking gaps that the final explanation never plugs. Puzzle addicts should leave this one alone.
