Its very much a academic work as its very well researched and looks very objectively at the man and his actions. There are a lot of pictures looks like 800 in the two volumes so, one would think its a pictoral document but, its probably the best work I have read about Heydrich. I got mine for £29.95 and £39.95 respectively so, it was a lot cheaper than I thought it would be. Its hard to recommend books as everyone enjoys things differently but, I do think this is a very good reference for those who have an interest in Heydrich.
