But suddenly a pall falls upon the Christmas cheer. The center itself is threatened with being closed down, a substitute that has been promised is withdrawn, a desperate young woman appears who begs for Alvirah's help in finding the baby she abandoned seven years earlier, and -- the final blow -- the little girl who is to play the Blessed Mother in the Christmas pageant vanishes. Alvirah is soon on the trail of the truth, which must be found before Christmas, which leads to the theft of a valued chalice that is somehow at the heart of the mystery.
A missing chalice. A missing child. A desperate mother. Who but Alvirah can sort it out in time for Christmas?
