Thirty-seven years ago two women were murdered months apart in Ontario. Years later, DNA led police to determine the same person killed them both. But who did it?

Terence McKenna and The Fifth Estate looks at examples of parents who attempted to foster genius, with dramatically different outcomes, "Recipe for genius."
