I agree absolutely that the P-38 was the best all-around twin-engine fighter of the war, but there was at least one other legendary twin-engine fighter (Well, it had fighter-bomber and night-fighter variants, at any rate. It saw extensive use as an interceptor, because of its speed.) in WWII: The Mosquito. I realize it was a wooden-framed fighter, but that was a big part of the key to its scorching speed and made it no less lethal. It was successful enough that the Germans attempted to copy its design, laminated wood frame and all. The Germans feared the bite of that mighty insect, day or night. BTW, I will check out that book. Thanks for the heads-up. I gave always been fascinated with that aircraft, even as a fairly young boy.
