The Adversary – Emmanuel Carrère

In the quiet Jura region of France, a physician goes completely haywire in a series of crimes that are hard for his friends and acquaintances to grasp. But then their grasp loosens further. And disappears altogether. Because the man at the centre, the man they thought they knew, turns out to be a dangerous and violent stranger. And now I know what it feels like to write a Dateline teaser. Non-fiction.
