Expectations for the annual holiday children’s event at the Reed Museum of Art and Archaeology are high, and Scarlett McCormick strives to make everything perfect since it’s her first Christmas as the museum’s head curator. At the event, the actors playing Santa and Mrs. Claus delight the children with gifts and stories, but then the couple disappears during their break. After a frantic search of the museum, Scarlett finds Mrs. Claus crumpled on the floor with Santa standing over her, clutching a knife. ’Tis the season for murder, and it’s determined that Santa is the prime suspect in Mrs. Claus’s death. To make matters even worse, Scarlett and Winnie Varma, the head of security at the museum, discover their newest security guard is missing along with a valuable artifact. As Scarlett and her friends investigate the crimes, they learn that Mrs. Claus made more than her share of enemies. With a long naughty list of suspects, it’s a race against the clock to solve the mysteries in the St. Nick of time. This clever whodunit from Annie’s Museum of Mysteries series is a must-read for fans of cozy mysteries, history, and female friendships.
