LOL. The sources in that "book" are very scant and dubious. The woman author, Mulcahy, relies on OSS reports, which have been mostly written off as anti-Hitler propaganda.
A lot of your book is lifted from a German professor named Machtan. Machtan himself also wrote a Hitler book, which is just about as bad as Mulcahy’s book. Machtan was mocked by actual historians.
Most of the Mulcahy book you posted is ridiculous speculation. Most reputable and scholarly historians observe that Hitler was not homosexual.
Btw, your posted book is not even in hardbound. It’s self-published. Mulcahy has a 4 year degree in history and writes crime novels.
