Clark, Dale "So Many - All Alike"

World War 2 tale. An American Magazine “storiette” (i.e., a very, very short story). Espionage in the Caribbean: a somewhat comely bar girl working in an unnamed Dominican Republic seaport is revealed to be a German agent who had traded intimacies for shipping information gleaned from unwitting Allied seamen. She’s finally uncovered when a practical “joke” played upon her by the wireless officer of a freighter (the fictitious JESSIE CRANE) that had been torpedoed and sunk by a German U-boat comes back to haunt her. The story ends on an O. Henry-esque note (and the unwritten reminder to all: loose lips sink ships!).
