The holiday season has arrived and bookkeeper/amateur sleuth, Sophie "Phee" Kimball, would love nothing more than to enjoy the comforts of her new home with her detective boyfriend near Arizona's Sun City West. Instead, her mother Harriet wants to showcase her chiweenie-chihuahua-dachshund Streetman in the Precious Pooches Holiday Extravaganza costume events. The festivities begin in October and end on St. Patrick's Day--with the winner starring in the St. Pat's Day parade. But things quickly turn an awful shade of green when Streetman uncovers a dead body under a tarp-covered grill in the neighbor's yard.
