Thomas Payne, while well-meaning and by no means a "revisionist" conspiracy theorist, had written what can best be described as a work of fiction.
Mr. Payne is not out to lie or decieve. But there are many parts of his book which, we now know (and he could have known when he wrote his book) that are based not on actual fact, but on bogus, sensational "biographies" of Hitler which have nothing to do with the truth. The problem with biographies of Hitler is that, being as close as humanely possible to absolute evil, one readily believes ANYTHING bad about Hitler. But it just ain't so in some cases.
1). Hitler as a lazy, dirty beggar in Vienna: Yes, Hitler WAS down-and-out in Vienna. But the description of the dirty, lazy beggar is lifted from one of the first bogus "biographies" of Hitler, by one Mr. Hanish, "I WAS HITLER'S FRIEND" from the 1930's. Hanish claims to have known Hitler in early Vienna - but facts prove otherwise; Arno Kubitzek, who really WAS Hitler's friend at the same (and slightly earlier) period, contradicts Hanish, and records also show that at the period Hanish supposedly "knew" Hitler as a pennyless beggar, he was living rather comfortably on his orphan's pension and the small inheritence he was left by his parents. The whole account of the period, which generally quotes Hanish, has all the touches of a melodramatic "made-for-TV" biography. Hitler is not only down-and-out, but "a figure rarely seen amoung christians" in his dereliction. He is not only supposedly helped with old clothes by kind merchants, but (what else?) by JEWISH merchants (I mean, where is the irony factor otherwise?), and so on. But it just ain't so.
2). Hitler's "visit" to England in 1911/12: this is complete fiction. It is lifted from another fake "biography" of Hitler, ghost-written as if by Hitler's sister-in-law, Bridgit [sp?] Hitler, who was married to Adolf's half-brother Alois Jr. According to this book Hitler visited Liverpool for almost a year and became (what else?) a burden on everybody, until he left back to Germany after a row with his brother. In fact, police reocrds show that at the time Hitler was supposedly "visiting" Liverpool (of all places) he was in fact living in Vienna.
The annoying thing about these two episode is that Payne adds insult to injury: not only does he rely on fictional accounts, but he makes far-reaching conclusions of the usual pop-psychology sort about the "origin of Hitler's evil" based on Hitler's "bad behavior" on these (fictional) occasions.
3). A "meeting" between the Soviets and Germans in 1943 in German-occupied territory: A whole chapter is devoted to this supposed "meeting". It never happened, as we now know for sure after the soviet archives had opened.
4). Hitler's suicide: Payne prints a photograph of "Hitler's" body, supposedly clutching a picture of his mother (!). This photograph came straight out of end-of-the-war time tabloid sensationalist press. It is now well-known that it is not a photograph of Hitler's body at all, but simply of a slightly similar man with a mustasche.
In conclusion, Payne does some basic research reasonably well, but one must say that his work must be read with great caution. You never know when Payne will swallow hook, line, and sinker one of the outrageous claims made about Hitler by bogus biographers, and present it as gospel truth.
