During a recent interview with Scott Naumann, Kim Eastland, and Jerry Wolking - longtime performers with the Quad Cities' interactive-whodunit organization It's a Mystery - the three routinely crack each other up with memories of overzealous audience participants, randy seniors, and that time when one of their performers, dressed in character, was mistaken for a prostitute at the Rock Island Arsenal Golf Club. ("On a positive note," jokes Naumann, "she made about $750 on the side.")
