Not to alarm anyone, but I think there may be a typo in the Richmond Hill Barn Theatre's program for The Diviners, because it credits Mike Skiles for the show's “Set Construction.” I'm pretty sure that's meant to say “No-Set Construction,” given that there's literally no set for director Jalayne Riewerts' production – just Richmond Hill's traditional theatre-in-the-round space decorated by occasional props. That's not at all meant as a put-down. This touching, graceful take on playwright Jim Leonard Jr.'s period drama succeeds primarily because of its bare-bones, Our Town-esque simplicity, and those qualities, happily, are mirrored in the engaged, heartfelt portrayals by Riewerts' cast.
