From publisher blurb:
Klaue is a FOOL!
A powerful member of the SS, Ludvig Weisse, demanded that he be the first to become a German ubermensch. Not caring that Doctor Jeste's formula was not yet tested, he consumed the potion that transformed him into the twisted and horrific Weisse Schaedel (PL 9).
Where once he was merely cruel, now he was a true monster. Assigned to, but not respecting, Hauptman Klaue, Weisse struck out on his own after WW2.
