Bernau, George. Promises to Keep
Divergence: 1963 CE
What if: The US presidential assassination attempt on November 22, 1963 failed.
Summary: Hunting down the conspirators, plus the elections of 1964 and '68.
Comments: Borderline alternate history, as despite the seeming setting in historical events, the names of all historical persons have been changed. Bernau's Candle in the Wind, Warner 1990 (0446514993), similarly treats the extended life of a Marilyn Monroe-like actress with false names but seems even less allohistorical.
