Field's book on the Kennedy assassination, The Evidence, was rejected by Random House in 1967. She decided to revise the manuscript: "a complete and total revamping of each page". However, she was unable to find a publisher. Her friend, Ray Marcus commented: "I know she was frustrated and disappointed about this, although she rarely said so - it would be super human for her not to be." He believed that if it had been published it would have been one of the most important books on the case.
Maggie Field told the Los Angeles Free Press in December, 1967. "Until we can get to the bottom of the Kennedy assassination, this country is going to remain a sick country. No matter what we do. Because we cannot live with that crime. We just can't. The threat is too great. There are forces in this country who have gotten away with this thing, and will strike again. And not any one of us is safe."
Maggie Field died of a blood disease on 31st July, 1997.
