The pics look interesting, maybe I'll get myself a copy, too!
But somehow I doubt that it can bring sth. new to the table because there are 2 superb German books on Spaghettis:
-"Für ein paar Leichen mehr" by Ulrich P. Bruckner
-"Willkommen in der Hölle" by Christian Kessler
Both essential I'd say!
