After his death

Chaucer died somewhere near the 1400, as it comes from the engraving on his tomb, which was built more than one-hundred years after Chaucer's death. There is some fanciful speculation—most recently in Terry Jones' book Who Murdered Chaucer?: a Medieval Mystery—that he was murdered by enemies of Richard II or even on the orders of his successor Henry IV.
