In a narrow rowhouse, she finds plenty of room for a big life

Many retirees opt for horizontal living - in ranchers, or in condos with elevators. Alice Hall went vertical. A year and a half ago, Hall, 73, a widow, moved to a narrow rowhouse in Center City. Her trinity, so called for the one room on each floor - a "Father, Son, and Holy Ghost" layout - has a steep, winding staircase and a skeleton in a closet.
