Two people have been poisoned, but by who? Mary is determined to find out and finds herself in the middle of a business scandal while she is at it. Unions, grudges, and money could all be motives, but finding the person behind it is harder than she thought. Being a funeral director and a coroner is rough business, especially during the Christmas season when love and light are in the air. But Mary takes us, once again, on a heart- warming adventure through the darkest days of death to a marvelous Yuletide discovery. Cold Snap picks up where Black Midwinter leaves off, continuing Mary Christmas Mystery Series.
