The Girl in the Polka-Dot Dress

In the early morning hours of June 5, 1968, The Girl in the Polka-Dot Dress ran down a fire escape, exclaiming, "We shot him! We shot him!"
"Who?" asked a witness.
"We've shot Senator Kennedy."
2018 - Fifty Years Later. Los Angeles County Deputy District Attorney Frank Caron is enjoying a highpoint in his career and the excitement of his new relationship with Sasha Frye. An amateur hypnotist, Sasha convinces him to let her treat his mother's dementia with hypnotherapy. It's supposed to do wonders for dementia-sufferers, but it backfires. Horribly.
Under hypnosis, his mother makes a most unusual comment. "I don't like this dress," she says. "But I have to wear it for him to die. And Robert Kennedy must die."
Frank is stunned. So is Sasha. What are they supposed to make of a comment like that? Can their new relationship handle the burden of learning such a shocking revelation?
One thing is for certain: neither can ignore it. What they do separately ignites the fire of ambition in Frank's over-zealous boss, the District Attorney. It upends the California legal system. And it reawakens an evil that didn't stop then - and won't stop now - to keep its secrets hidden.
Through it all, there's one burning question Frank must have answered: was his mother a conspirator in the assassination of Senator Robert F. Kennedy?
What he learns is far more than a simple yes or no.
