Author Andrew Nagorski reconstructs how a motley group of people narrowly saved Sigmund Freud from the Nazis. Four sisters of the father of psychoanalysis, who managed to escape from Vienna after the Anschluss in 1938, died in the camps, three of them gassed in Treblinka.

“If Freud had stayed and had not died before the cancer that ended up killing him in London, the Nazis would have murdered him,” says Nagorsky.
