Read the novella length Amok
as published by itself in a tattered English edition from 1931. (Hooray for university libraries!)
The colonialism and attendant racism age this book but nonetheless underscore what was and wasn't done during a very specific time and place. Also, Zweig hits the notion of "running amok" very heavily and none too subtly. But as the story of a man out of control this still has a certain draw as obsessive passion leads to the downfall of a German doctor serving in Malaysia.
If I didn't tend to be a ratings hardass, this would be 4 stars.
