Cahill was a teenager back then, wire thin with long, chestnut brown hair framing her face. One cousin was playing outside that day and Cahill had another little one in a high chair in the kitchen. So when she saw the nun leaning over the baby, Cahill said, she sprinted outside to protect the child. The woman introduced herself as Sister Eileen Shaw, telling Cahill that she was out on a walk from her nearby convent. The two struck up a conversation, Cahill said, which led to an invitation for the teen to play guitar at an upcoming Mass. That invitation led to more special treatment, private phone calls and private trips.
