Who pushed Schoenzimmer down the elevator shaft in the lobby?  Sheila or the actress playing her?  And who got pushed?  Was it Schoenzimmer, the philanthropist sponsor of tonight’s production of Eavesdrop, his real-life double, or the actor playing him?  And why?  Was it for money, revenge, or to rebalance the world after the tyrannical patriarch’s lifelong abuse of his family, friends, and massive wealth?  All questions are answered—mostly—in this start, stop, and restart romp through a troubled performance of an otherwise straightforward comedy about three elderly siblings and their eviction from the rundown home in which they live.
