Continuing in the series, Adolf Hitler and His Submarine or Adolf vs. the Mafia is Book four of the Hitler Chronicles, (but the second book published). In this satirical mashup novel our hero, Adolf Hitler, learns of Canadian gold laying in a sunken ship, on the bottom of the ocean near South America. This gold was destined to aid a Pro-Eugenics revolt in various banana republic's and Adolf decides he and his father should take their new submarine, The Sea Lion, and set out find the gold for themselves. Meanwhile, the evil eugenics Prime Minister Tommy 'The Needle' Douglas and his grandson, Jack Beck, make a deal with the American Mafia to capture the Sea Lion, the Hitler's, and bring back the gold. The race for the gold is on, with Adolf and crew fighting the Brazilian navy, the Mafia and their submarine The Stugots, as well as creatures of the deep. Many historical characters are introduced into the story, including eugenics supporters George Bernard Shaw, John Kellogg, and many characters from the last book return. Tom does battle once again with young Winston Churchill, and his friends, Joey Steele, Frankie Roosevelt. Submarines, counterfeit money, mafia dons, capos, solders, enemas, corn flakes, a swarthy navy the Clean Bowel Battalion and a true Southern Gentleman are all mixed together, mashed up and presented for your enjoyment. A black comedy with layers of subtle satire, parody and a little history tossed in that makes Adolf Hitler and his Submarine a great book. For those who liked Adolf Hitler and his Airship they won't want to miss the action and leadership that only Adolf Hitler can offer. The action in this book takes place after Adolf Hitler and His Airship concludes.
