Query: Interesting material but disappointing

To me this book promised more than it delivered. For a start itwas written in a journalistic style, for example sentences thatwere regarded as important were shown like headings in bold typee.g. "in a journalistic style"I for one found this annoying particularly as the author is aprofessor and should have written a more scholarly book.The book deals with all of Hitler's life. It tells how he rose to power and once he became Fuhrer dealt more and more severelywith any real or imagined opposition. The most famous oppositionof course culminated in the July 20 1944 bomb plot. His coverageof this is quite good and he shows that even though Hitler wasnot killed the conspirators might have seized power if they hadnot hesitated and waited for others to act.There is a good selection of black and white photographs.
