Isabelle Montaigne is looking forward to a weekend ski trip to the Potomac Highlands, but things get off to a bad start when the tour bus slides off the highway in a blinding snowstorm. This is only the precursor of worse disasters; after finally struggling through the snow to reach the lodge, Isabelle and her cousin Ashley discover the body of a ski instructor, killed by a blow to the head. Unfortunately, Ashley had an argument with the dead woman in front of all the employees of the ski school—and now she's the prime suspect. Isabelle knows her cousin isn't capable of murder, but the only other person who shares her opinion is Jack, Ashley's ex-boyfriend. Ski school authorities and Sheriff Ward Sterling will have to be convinced of Ashley's innocence. Isabelle knows the only way to prove Ashley isn't the killer is to find out who is. She and her cousin begin searching for clues immediately as the snow piles up, cutting off phone service and highway travel. Was Jack involved? His fling with the dead woman poses questions. What about blackmail? There's evidence of that, too. Can Isabelle sort it all out before Ashley is charged with murder?
