Sharon Evans's portrait of a troubled Chicago sex-crimes cop boasts an intriguing concept. At the story's center is Jim, whose glib detachment crumbles after a rape victim he's disrespected places a curse on him. Jim's already strained relationships with his current and former partners and his lieutenant--all women--become even more tense when he's pursued by three Furies, ancient Greek goddesses of vengeance. Evans and director Peter Amster's excellent cast convey the odd combination of drudgery and danger in police work and the psychological stress on the officers as they deal with lying perps and devastated victims. But Evans's uneven juxtaposition of police-procedural realism and mythic fantasy gives the play the patchy feel of a work in progress. --Albert Williams a Through 7/1: Thu-Sat 8 PM, Sun 7 PM, Live Bait Theater, 3914 N.
