‘Six Corners’ at American Blues Theater: Murder at a train stop, seen in shifting lights

Review: Nick Moroni and Bernadette Perez are married (not to each other) mid-career Chicago cops burning late oil at the precinct shop, bantering, shuffling papers, watching the clock, waiting to check out so they can check into a motel together. This little slice of their lives provides the frame for Keith Huff’s “Six Corners,” a pulp-fiction drama at American Blues Theater that modulates from sad to sadder before it ends in the precincts of nobility. ★★★
