It's Christmas Day in the sleepy town of Sorenson, Wisconsin, but instead of unwrapping presents, deputy coroner Mattie Winston is at the burnt remains of a house, where a charred body has been found. The victim is none other than Jack Allen--a paraplegic who recently won a huge casino jackpot. Upon closer inspection, Mattie and detective Steve Hurley are convinced Jack was murdered to steal his winnings, giving the phrase Black Jack a whole new meaning. . .
But as Mattie investigates, even her cutting-edge forensic skills keep coming up short in a case with as many suspects as twists. After her odds-on-favorite turns up dead, Mattie and Hurley must race to find a killer before another victim cashes in his chips.
