The Terrible Secret, Revisited

Tyler Cowen today, reviewing a book:

I also learned that many Berliners starting suspecting the Holocaust because of the rather efficient German postal system. When letters would be sent to "ghetto inhabitants" on the Eastern front, often they would be returned with notice that the intended recipient had passed away.

This made me remember a book I read years ago, The Terrible Secret, by Walter Lacquer, which documented a lot of the "leakage" of the secret to the West.

Stories came out and made the newspapers, but more as rumors than as solidly verified reportage. The Germans were actually effective in keeping the Allies from fully grasping what was taking place. Not that the Allies were paying much attention to these stories, anyway.

A flimsy screen
hid the murder machine.
