It was nobody's fault, unless you counted the mice, and even they didn't mean to start trouble. A forgotten candy cane lured them to the Christmas tree stored in the basement of St. Anne's Hospital. The nibbling and gnawing just went on from there. Now there are holes in the trunk where none should be and not a single branch will stay in place. Despite this disaster, the nurses of Psychiatric Ward One are determined to deck the blues by decking the halls. When an anonymous donor sends them an artificial balsam, they happily press their patients into decorating it. But lighting the new tree ends with a bang! Who planted the bomb that wrecks havoc in the little town of Rhineburg? A frustrated employee fired by St. Anne's despised administrator? A student terrorist from Bruck University? Or Caroline Rhodes, a nurse with a suspicious past who survived the explosion but refuses to discuss it? Tagged as a suspect by the FBI, Caroline must prove her innocence by unraveling a devilish plot devised to eliminate one man's nemesis. Aided by history professor Carl Atwater, Caroline cuts through a maze of conflicting stories, red herrings, and downright lies to bring a killer to justice.
