When Sam Reynolds, the Portland (Ore.) cop investigating Dr. Lucinda Frazier's murder, asks, ``Anyone you know want to see her dead?'' her lesbian colleague Morgan McRain replies, ``I don't know any voyeurs.'' Seriously, though, neither Morgan nor Sam believes Lucinda was killed by the anguished fetishist she was treating, even though the patient insists on confessing to the murder. The perp could've been anybody in the Chandelier Club, Morgan's swingers' circle--five couples happily (?) entangled with each others' spouses (though, one of them insists, no gays or funny stuff). But the circle narrows when a second member is killed by somebody who seems equally fascinated with her footwear. Newcomer Hartman has a light touch--maybe too light--with sexual hang-ups of every stripe. Just listen to the killer on shoes: ``Nothing to tell really. I like them.''
