Query: HARRY HARRISON LOSES FACE

Harry, how could you! After creating the inimitable Stainless Steel Rat, you put in in a STUPID non-existent storyline! You send Slippery Jim back and forth in time aimlessly, the archvillain is titled "HE" (was that name the best you could do?), and then the end is not the least satisfactory. Harry, the absurd point of the story was to make sure the Stainless Steel Rat could not be around to be a father to his twins. What a disappointment when the best part of the story is the brief repartee between Slippery Jim and his boss, Inskipp. I know you can do better, Harry, because you have in your other books. Readers, if you like the Rat, skip this one.
