A psychology professor's search for his missing wife launches us on a time-hopping fugue, weaving together the stories of Stalin's daughter defecting to America, the son of a white supremacist growing to doubt the beliefs he was raised with, and the secret despair of becoming an accidental killer. In This Much I Know, Jonathan Spector takes us on an explosively theatrical interrogation of how we make decisions, how we change our minds, and how much responsibility we bear for the things we do not control.
