The latest thrilling installment in the bestselling Mercy Carr mystery seriesMercy and Troy are looking forward to baby Felicity's first holiday season, and they're determined to make it a Christmas to remember. At Northshire's annual Solstice Soirée, hosted by Northshire's finest and funded by Mercy's billionaire pal Feinberg, Amy's little girl Helena is sitting on Santa Claus's lap. She's telling him she'd like a Bitty Baby doll just like little Felicity when the bearded man leaps up, thrusts the toddler at her mother Amy, and staggers away from the festivities. He disappears into the woods. By the time Elvis and Mercy find him, Santa Claus aka the town mayor, is lying on his back, dead. A yule log made of oak sits on his chest, burning bright, a beacon of light on the darkest day of the year. This strange murder is the first of a series of similar Solstice-themed killings targeting the town's most prominent citizens. Beloved family friend Lillian Jenkins, the grande dame of Northshire, could be next. Mercy and Troy and the dogs must team up with Thrasher and Harrington to capture The Yuletide Killer before he strikes again, this time far closer to home.
