Cass Peake's web design company accepts a job to bolster the local college's efforts in attracting new students. With the winter break, she and her colleagues expect a very quiet campus. What they don't anticipate is the reunion of a strange secret society called The Black Triangle Club on the grounds... and a dead body. Then corpses start piling up like gifts under a Christmas tree. Coincidence or not? With the help of her ghostly friend Doris and other allies, Cass works frantically to uncover the real killer. But it might take a real holiday miracle to solve this Yuletide mystery.
