Robert R. McCammon – The Wolf's Hour (Pocket Books, 1989, 603 p.)
D-DAY IS THREATENED, BUT ONE MAN COULD IP THE HEART OUT OF THE NAZIS - WITH HIS BARE CLAWS
He is Michael Gallatin, master spy, lover – and werwolf. Able to change shape with lightning speed, to kill silently or with savage, snarling fury, he proved his talents against Rommel in Africa. Now he faces his most delicate, dangerous mission: to unravel the secret Nazi plan known as Iron Fist. From a parachute jump into occupied France to the lush corruption of Berlin, from the arms of a beautiful spy to the cold embrace of a madman's death machine, Gallatin draws ever closer to the ghastly truths about Iron Fist. But with only hours to D-Day, he is trapped in the Nazis' web of destruction …
I guess this is one of McCammon's pulpiest. A werewolf-spy fighting the Nazis.
Back then this wasn't translated. My guess is that this was a matter of sensibilities. Scenes of werewolf torture in a fictious concentration camp were probably deemed off-putting and tasteless. Frankly I can understand this. I also wasn't too keen on it. 25 years later it was published. Times change.
