Sugar Cookies and Murder — Summer Prescott; Carol Durand

Echo and Carla are at odds again, after the Interior Decorator does her best to embarrass the laid-back Californian at a holiday dinner party, and unfortunate incidents follow. Did Carla finally go off the deep end and embark upon a mission to scare Echo into returning to California, or is something more sinister afoot? Spencer uses his resources to check out what's been going on with Echo, and discovers something so dark that the entire gang may be scarred by tragedy if he and Chas don't put a stop to it. Christmas is just around the corner, and Missy has a whole host of surprises that'll be sprung upon her, some good, some potentially deadly.
