Kori Price Brichter planned on a wonderful Christmas. She and her police officer husband, Peter Brichter, had invited their friends, Frank and Mary Ryder and Gordon Ramsey, to spend the holiday with them, their son Jeep, and their nanny, Jill. Most important, Kori had invited Evelyn Biggins to join them.

Since the guests were now isolated in house because of a blizzard, the only possible conclusion is that one of them had killed Evelyn. But who?
