In a renovated Gothic church on Long Island lives Jonathan Hemlock, an art professor and a world-renowned mountain climber who finances his black-market art collection by working as a freelance assassin. Now, Hemlock is being tricked into a hazardous assignment that involves an attempt to scale one of the most treacherous mountain peaks in the Swiss Alps: the Eiger. His target is one of his three fellow climbers. The problem is that the CII can't tell him which one. This spine-tingling adventure, part thriller and part satire, introduces an intriguing cast of villains, traitors, and beautiful women into a highly charged atmosphere of danger and suspicion that builds to a death-defying climax.
