The investigation reveals that the assumed accident was but one link in a chain of murders. Blake works with his colleagues at ABC Consultants and a covert government agency to determine the presumed impostor's identity and activities and to solve the murders. The coordinated effort to solve the puzzle involves incidents that span the period between World War II and the present, some of which have national and international implications that may affect the future.
