She was a longtime lover of JFK.

She was the ex-wife of a CIA chief.

She was the sister-in-law of the Washington Post’s Ben Bradlee.

She believed in mind expansion and took LSD with Timothy Leary.

She was a painter, a socialite and a Bohemian in Georgetown during the Cold War.

And she ended up dead in an unsolved murder a year after JFK’s assassination.

The diary she kept was never found.

Until now. . . .
