The Dangerous Otto Katz : The Many Lives Of A Soviet Spy
by Jonathan Miles

Uh oh, another spy book ending up on this blog. That wasn't planned originally. The book started out being terrific and was exciting. It came to a screeching stop after one hundred pages. Too many peripheral people were mentioned and what had been interesting just turned flat.
Otto Katz was an anti-Fascist and trained by the Soviets and was able to alert the world, early in the 1930s, on what the Nazis were doing. He was a lover of Marlene Dietrich and was very involved in Hollywood. Katz did a whole lot more but I never arrived at that point.
Enough of this genre for a while unless something worthwhile comes along.
Not recommended.
