Rhonda Brown has a terrific warmth and vitality on stage, and these qualities were evident in her portrayal of Linda in the Miners Alley Playhouse production of Fiction, Steven Dietz's tricky Rubik's Cube of a play. Linda, a writer and prickly intellectual, has been diagnosed with a fatal brain tumor and has asked her husband — also a writer — to read her journal after her death. In return, she wants to read his — before her death, naturally. What follows is an entertaining mishmash of truth and deception, reality and falsification — and then it turns out that Linda's diagnosis itself was an "oncological misapprehension." But audiences had no problem navigating this maze of mixed meanings, because Brown led them through it with so much charm and authority.
