It's the deadliest thyme of the year... With snow dusting the ground and sauce sizzling on the stove, local chef Tessa Esposito is ready to serve up some holiday cheer. And with the annual Festival of Lights underway, it seems nothing can dim her spirits. Not even Mario Russo, the newest scrooge in town whose espresso bar has been quickly disrupting businesses and stealing customers from Harvest Park's favorite coffeehouse. But when Mario is discovered at the festival's opening, face down in a Santa suit, Tessa realizes the bah humbug runs deeper than she could have imagined. And when one of her dearest friends is implicated in the crime, she must make a list of Mario's enemies, check them twice, and discover the cold-blooded killer. Especially before they can sleigh again.
