In 1950s New York, Detective Michael Cassidy investigates a number of bizarre deaths while trying to avoid being assassinated himself. New York, 1956. A couple walking through Central Park on a fall evening are confronted by a hansom cab driver, only to kill him and casually walk away. Who are the couple and did they know the man? A man commits suicide by throwing himself through a hotel window. His colleagues claim he was depressed - but is there more to it than that? Before Detective Michael Cassidy even begins investigating these cases, he is threatened by an unknown man ... the reasons for which are unclear. Are all three incidents connected? If so, how, and will Cassidy live long enough to find out before his would-be assassin claims his life? --Amazon.
