Having now finished "Driving Forces", I am left feeling that yes - perhaps there is a better book in there. But I wonder if Stevenson is the man to write it (and/or if Bentleys are the publishers to produce it), since two of the most glaring errors of fact in the later chapters are that:
Pau is apparently in Belgium.
When discussing the imprisonment of Ferdinand Porsche by the French, Stevenson claims that one of those who secured his release was Marcel Lehoux. Quite difficult, considering Marcel had already been dead for ten years: the person he meant to feature was Charles Faroux.
Overall, I was disappointed in this book - Stevenson often seems to fit the facts to his arguments, rather than the other way round, and as I mentioned before he plays tricks with the chronology - as an example the book discusses Seaman's win in the 1938 German GP. In the next chapter, we move on seamlessly to the Swiss GP. Fine, you might think. But three paragraphs in we suddenly encounter Ernst von Delius! "Ernstchen" was killed in the 1937 German GP and we have actually jumped back two years
to the 1936 Swiss GP. Stevenson does things like this regularly in the book, but if he provided chapter and verse on dates and arranged events in the correct order I have a feeling that a lot of his arguments would fail to stand up to scrutiny.
I haven't really touched on his interpretation of Nazi history, which is perhaps best described as "selective": as another example, the Night of the Long Knives is portrayed as Hitler's backlash against a homosexual "mafia" at the head of the SA. I'm aware that Roehm was homosexual, but from my memory of what I've read on this I don't think many other SA leaders were. As David Irving's "Hitler's War" is quoted as a major source, I have to say that his basic research may not be based entirely on unbiased material - although OTOH both Toland's and Fest's biographies of Hitler are mentioned in the bibliography.
