Cecily's friend Madeline arrives with her new baby and adds a kissing bough to the decorations. Cecily believes that the holiday couldn't get off to a better start…But after a footman and a new maid are seen kissing under the bough and then turn up dead afterwards, the downstairs staff is convinced a serial killer is among them…perhaps the mysterious guest known only as J. Mortimer. When Madeline's baby disappears, Cecily desperately tries to find the child. If she doesn't catch this killer in time, everyone's cheer will quickly turn to fear.
