A woman I know : female spies, double identities, and a new story of the Kennedy assassination / Mary Haverstick.

Enhanced descriptions from Syndetics:

The "fascinating" ( The New York Times ) true story of a filmmaker whose investigation of her film's subject opened a new window onto the world of Cold War espionage, CIA secrets, and the assassination of John F. Kennedy.

"A compelling real-life thriller."-- The Telegraph (UK)

Independent filmmaker Mary Haverstick thought she'd stumbled onto the project of a lifetime--a biopic of aviation pioneer Jerrie Cobb, the key figure in a group of extraordinary women who in 1960 passed the same tests as the legendary male astronauts of the Mercury 7 but never went to space. Just as casting was set to begin, Haverstick received a mysterious warning from a government agent; soon she began to suspect that there was more to Jerrie's story than what met the eye. As she dug deeper, she discovered that Jerrie's life shadowed that of a mysterious CIA agent named June Cobb, whose espionage career traced an arc of intrigue from the jungles of South America to Fidel Castro's Cuba, to the communist literary circles in Mexico City--and ultimately into the dark heart of the Kennedy assassination in Dallas.

Haverstick's attempt to learn the truth directly from Jerrie would plunge her into a cat-and-mouse game that stretched across a decade, deep into a thicket of coded CIA files. As she uncovered a remarkable set of mostly unknown women whose high-stakes intelligence work left its only traces in redacted files, she also found shocking new clues about what really happened at Dealey Plaza in 1963. Offering fresh insight into the Kennedy assassination and a vivid picture of women in midcentury intelligence, A Woman I Know brings to life the astonishing duplicities of the Cold War intelligence game, a world where code names and hidden identities were the lifeblood of spies bent on seeking advantage by any means necessary.
