After a pared-down season last year, Valley Summer Theatre has returned with not one, not two, but three sure-to-please shows this summer. The first is Marion Bridge, Daniel MacIvor's well-known and well-loved play about three sisters who hold a bitterly comic vigil over their ailing mother. Next is Wingfield Unbound, another instalment of the popular Wingfield series starring the elastically funny Rod Beattie. Finally, Pamela Halstead directs Mass Appeal, a two-character comedy-drama about a generational divide between a pair of priests. —Kate Watson
