Murder on the Menu: an Al Pennyback mystery

Competition in the restaurant industry is cutthroat, but it's not supposed to be literally fatal. When Al and Sandra accompany Buster Mayweather to upstate New York to attend the opening of a new restaurant by Buster's old college friend, things take a turn for deadly when the restaurant's head chef is found frozen to death in the freezer. Was it an unfortunate accident, or was the chef the victim of one of the town's many long-standing feuds? Buster, a DC cop, is outside his jurisdiction, but when a friend's in need, jurisdiction be damned. Al just hates to see injustice, and is a sucker for a difficult problem, and what's more difficult than a murder with no motive, but a town full of suspects?
