An agent of the U.S. State Department dispatches the Hardys on an ultrasecret mission to track an international hit man in the Little Panaslava section of River Heights. But the Hardys don't know the identity of the assassin, or of his target, the exiled prince of Panaslava. Joined by Nancy Drew, Frank and Joe Hardy must slowly penetrate a wall of silence surrounding Little Panaslava--to make a shocking discovery.
Carolyn Keene and Franklin W. Dixon are the pseudonyms under which many ghostwriters penned the Nancy Drew and Hardy Boys series, respectively. Both series were created by Edward Stratemeyer, founder of the Stratemeyer Syndicate book packaging firm, in the late 1920s and early 1930s.
Stratemeyer's daughter, Harriet, and syndicate writer Mildred Wirt Benson were the two people primarily responsible for bringing the iconic character of Nancy Drew to life in the minds and hearts of millions of readers around the world.
