Historical Letters

When Anne Sebba was researching Wallis Simpson for the recently released biography on the American who would prompt the King of England to give up the throne and marry her, Sebba came across a packet of letters "never seen publicly before." The letters were written by Wallis to her not-yet-ex-husband, Ernest Simpson.

According to the CBS Sunday Morning Show, the letters reveal a "troubled, even tortured woman" torn between her past and future.
