With Old Town's DIY Home Decorating Festival in full swing, Sophie's swamped, juggling a bumper crop of artisans, antique dealers, and decorators for the busy street fair. Still, when her best friend Nina suddenly needs a ride from the airport, Sophie is happy to help . . . until she sees Nina disembarking in a state of disarray. It's obvious the trip to Portugal soured somewhere along the way. But after one of Nina's traveling companions turns up murdered the following day, Sophie knows something is truly rotten . . .

Though the crime scene is staged to look like an accident, Sophie isn't fooled and peels off to conduct her own investigation. Her only clue is a strange image the victim scratched into the soil before dying. Could it point to a cryptic killer in Old Town? A bitter travel adversary? Or a cursed artifact smuggled back from the trip? As the mystery grows, so does the body count, and if Sophie doesn't pluck the murderer soon, her best friend may be the next to fall . . .
