Bad romance

The Daily Beast rounds up eight great "literary love affairs," including the Shelley-Byron-Shelley love triangle, but I think we can do better. The only thing worth noting of Norman Mailer and his 18th 6th wife is that someone still married him after he tried to kill one of his other wives. But then, I'm sure that's what they said about Henry VIII. Hemingway wrote a play about his and Martha Gellhorn's relationship called "The Fifth Column" that is probably his most moving work, and (thus?) naturally very hard to see staged.
