On the outside, Dr. Jeremy Balint is a pillar of the community: the youngest division chief at his hospital, a model son to his elderly parents, fiercely devoted to his wife and two young daughters. On the inside, Dr. Jeremy Balint is a high-functioning sociopath - a man who truly believes himself to stand above the ethical norms of society. As long as life treats him well, Balint has no cause to harm others. When life treats him poorly, he reveals the depths of his cold-blooded depravity.

At a cultural moment when the media bombards us with images of so-called sociopaths who strive for good and criminals redeemed by repentance, The Mask of Sanity offers an antidote to implausible tales of evil gone right. In contrast to fictional predecessors like Dostoyevesky's Raskolnikov and Camus' Meursault, Dr. Balint is a man who already has it all - and will do everything in his power, no matter how immoral, to keep what he has.
