How Did Inga Arvad Die?

Inga Marie Arvad Petersen was a Danish-American journalist who was a guest of Adolf Hitler at the 1936 Summer Olympics and also had a romantic relationship with John F. Kennedy in 1941 and 1942. The juxtaposition of these facts led to suspicions during World War II that she was a Nazi spy. Secret U.S. investigations uncovered no such evidence, and her past did not harm her professional life or social standing in the United States.
