On Christmas eve, Rabbi Oud Ramonides visits the local Great Elm Preservation Society, and discovers a pile of dusty texts. With the help of Rev. Lanzarotte he ascertains that the Seven Dials roundabout was built on the intersection of two lay lines. This has to be the location of the camphorwood casket containing the Urim and Thummin which would have been buried here in the fourth century (after the mediterranean earthquake) on the Tuesday after the Romans left. He scuttles along to the roundabout where he hears strange emanations from the Christmas Tree – eerie sounds of meditating wildebeest singing Christmas carols.
