Matthew Wilson's elliptical noirish play for Hysteria Productions opens with a fantastic scene: two men at a costume party, one dressed as Superman and the other like Sherlock Holmes, engage in a Hitchcockian cat-and-mouse conversation on a high balcony. Turns out that the Holmes impersonator (played by Wilson) is a shrink, Ray, who's treating the former girlfriend of Ken, who may or may not have slashed the woman's face. Ken wants access to Ray's notes on Barbara and tries to blackmail him with information from his past. James G. Berner's staging is too deliberate at points, undercutting the story's underlying tension, and the intentionally vague resolution may frustrate some viewers. But it's an intriguing piece that with more work should realize its full potential. North theater, 7 PM.
