Harold the Hawk at the Baseball Game is the third book in the Cousin Adventure Series which finds Colt and his cousins in a three-part adventure beginning with struggling to stay above the high waters and the swift current of a deluge-filled creek. After a rescue and a series of newspaper interviews, the story of the boy's harrowing adventure reaches the desk of several very famous athletes who grant the boys their dream of a lifetime! As storms roll into Denver and a downpour floods the baseball stadium, the boys seek shelter beneath the field only to be lost in a maze of dark tunnels and rapidly rising water. In the darkness and with an overwhelming sense of growing fear, the boys' hopes grow more and more dim.
