Dark Hero [EPUB ebook] 

Rene Burg, one-time Chicago gunman, finds himself mixed up in the Norwegian underground movement during the war. As well as gunning for the German Army in general, Burg is out to get one person in particular: a beautiful deadly woman who has brought the technique of double-crossing to a fine art. And he doesn’t have much time, because they are both under sentence of death.
