She lost her virginity to him on her fourth day at work.

In Once Upon a Secret, for the first time, Alford has revealed every detail of her experiences as Kennedy's mistress - an affair that was ended only by his assassination.

Mimi has decided, after 40 years of silence and deep reflection, to tell her story.
