Lydia Benecke: Auf dünnem Eis
Lydia Benecke is a German psychologist who specialized treating criminals and writes boosk on psychopathy.
This one was a recommendation my wife got from one of her pupils.
For me it is not as well as "The Wisdom of Psychopaths" by Kevin Dutton, which I read some years back.
The Master and His Emissary by Iain McGilchrist [audiobook].
"The differing world views of the right and left brain (the "Master" and "Emissary" in the title, respectively) have, according to the author, shaped Western culture since the time of the ancient Greek philosopher Plato, and the growing conflict between these views has implications for the way the modern world is changing. In part, McGilchrist's book, which is the product of twenty years of research, reviews the evidence of previous related research and theories, and based on this and cultural evidence, the author arrives at his own conclusions." ~ wiki
