Crocker IIISimon & Schuster, 224 pages, $28.99CIA founding father “Wild” Bill Donovan propels W. H. Crocker III’s historical novel Kruger’s Korps by handing a glossy photograph to titular character Rolf Kruger. A spymaster, a doppelganger, and a world war — one can almost predict what happens next and indeed this scene sets up the rest of Kruger’s Korps. Kruger’s Korps, less comedic and more cinematic, similarly allows the reader to pass the time more pleasantly without the obligatory sermons so many authors regard as more important than story. The secret to success for a conservative novelist involves more novel, less conservative. Kruger’s Korps leads not to enlightenment but adventure.
