Clark Savage Jr. aka Doc Savage was at his Fortress of Solitude when his empathic abilities sense something is wrong. So he returns to New York and is informed by his confidants, The Fabulous Five that his father, a missionary died somewhere in South America of a tropical disease. He is also told that his father sent him something before he died, and his associates locked it in his safe. He was about to open it when someone takes a shot at him but misses. Doc chases him down and he falls to his death. He appears to be some kind of native, quite possibly from South America. Someone blows up the safe destroying the papers his father sent him, and Doc's empathic ability goes off again, telling him that his father was murdered. Doc decides to go to the country where his father died to see if he can find out what happened. But after their plane takes off someone tries to shoot it down but Doc had the foresight to send a drone. When he gets there someone tries to kill him, in a peculiar manner.—[email protected]
