Christmas is the most important holiday of the year. After the corresponding days that exalt the national pride of each country, such as Independence Day in the United States, Victory Day in Russia, or Bastille Day in France, it's December 25 that articulates the life, the work, and the economy in much of the world, including many non-Christian countries. Since ancient times, the beginning of winter has been the occasion for most people to eat, drink, dance, and get together to beat the drum and take a break.

Dr. Dylan Reinhart wrote the book on criminal behavior. Literally - he's a renowned, best-selling Ivy League expert on the subject. When a copy of his book turns up at a gruesome murder scene - along with a threatening message from the killer - it looks like someone has been taking notes. Elizabeth Needham is the headstrong and brilliant NYPD Detective in charge of the case who recruits Dylan to help investigate another souvenir left at the scene - a playing card. Another murder, another card - and now Dylan suspects that the cards aren't a signature, they're a deadly hint.
