Book Review: The Nazi’s Wife: A Thriller by Peter Watson
(Four Stars)
“When your brother is a Nazi; you can’t ignore evil forever.”
Historical fiction, yes; a “thriller”? Not so much. Well written. Close first-person narrative of an art recovery expert after VE Day. Published in 1985; there’s been a sea change in Europe since.
“… People who realized that they would never have as much purpose in their lives, or as much self-respect, as the war had given them. … would never be so happy.
Encyclopedic knowledge of Austria and its art and culture, especially near Salzburg. Much of his knowledge about the inner workings of the army and soldiers seems drawn from hearsay. Watson loves semi-colons; commas, not so much. His punctuation occasionally distracts.
“I joined the army to fight Nazis not to fall in love with their wives.”
Respectful of the religious beliefs of Germans in a way no longer routinely found in literature, but is vital to understanding the motives of some characters.
“The war was over; it was time to put away wartime things.”
As a Matter of Fancy 
Sounds interesting. Your description helps to make it feel familiar, probably read something similar years ago. Thanks.
