It’s the tragic story of an aging king and his three daughters. Who loves him most? That’s what Shakespeare’s King Lear asks his daughters amid the nobility who have gathered as he prepares to step down from the throne.“He decides to divide his kingdom into three parts, one for each daughter,” explained Dave Johnson, director of Cookeville Leisure Services’ 14th annual Shakespeare in the Park series, which opens Sept. 29 at 7 p.m. at the Dogwood Park performance pavilion.
