Prior to last Thursday, I had seen 40 productions at Mt. Carroll's Timber Lake Playhouse, and somehow, during all those visits, I had never been there when it rained. Yet rain it did on Thursday, and it rained hard, and I couldn't imagine more fitting weather for the venue's opening-night performance of An Inspector Calls, an eerie, succulent psycho-drama (with laughs) that made the literal storm clouds a spectacular match for the figurative ones on-stage.
