Denise Fennell returns as "Sister" in the holiday production of Sister's Christmas Catechism: The Mystery of the Magi's Gold. It’s CSI goes to Bethlehem as Sister takes on the mystery that has intrigued historians throughout the ages: On the night of that famous holy birth, what happened to the Magi’s gold?

Forensic tools in hand, and assisted by a helpful flock of audience members, Sister hunts over manger and under camel hump in her relentless search for the culprit. Along the way, she gives her class a history lesson on the origin of nativity sets, provides line-by-line analysis of favorite Christmas carols, and creates a living nativity unlike any person has ever seen.
