Flynn, T. T. "Gratefully Yours."

Argosy tag line: “In Puerto Bari it was possible to kill a man with nothing more deadly than kind words.” Flynn’s tale concerns a World War 2 Nazi espionage ring operating out of a Central American port city which is broken up by an alert American who turns the gang against its chief source of information, a sleazy waterfront bar owner named Carlos Estaban. Estaban had been feeding the Germans information on Allied Caribbean, Panama Canal and Pacific Ocean shipping movements, and the Nazis, in turn, had passed the valuable information on to a waiting Nazi “sea wolf,” a warship posing as a merchant vessel. By tale’s conclusion, the raider has been destroyed by the U.S. Navy, Estaban himself murdered by his Aryan employers (they thought that he’d double-crossed him) and the Germans taken into custody.
