Alone in the basement, Jeanne Boylan sketched into the night. She didn't even stop to eat, afraid if she did, she might never continue.

For more than 20 years, two faces had haunted her. In nightmares, she could still hear them taunting her, two strangers who, on a lonely country road, stole long and unforgettable hours of her life.

Even today, Boylan talks about the attack haltingly. "I just wanted to forget," she said. "To get on with my life, not to feel they had taken anything more than that one night."

In fact, Boylan acknowledges now, that night determined every decision about her life since. It began her journey of exploration into the workings of the human mind. And it began her transformation into who she is today, a woman who helps capture murderers and madmen.
