This Much I Know

A tenured professor of psychology, Lukesh enjoys a life as organised and logical as his mind. But then his wife vanishes, sending only a text message by way of explanation and leaving him to re-evaluate their relationship. He discovers she has embarked on an epic odyssey, crossing and recrossing Russia and delving deep into Soviet history on a quest to unravel a family mystery of which he was unaware – one in which Josef Stalin himself may be involved.
