OMG! Do not bother with the Man in the High Castle or anything by Phillip K. Dick, ever. That was a horrible story! Just stupid.
The men in the meeting were ambushed and ended up killing some random Nazi guys. Why? Who knows? The story didn't say anything else about that. It just used it send one of the men into a boring existential crises involving a piece of jewelry he got from the jewelry makers. In it he envisioned very briefly a world where the Allies won the war. As soon as it started it was over. He then had a heart attack and we never see him again. A woman in the book discovers her lover is a Nazi sent to kill the man in the high castle for writing the book. She kills him and goes to see the man himself. There she reveals that the book they are all reading is, in fact, the truth. The Allies did win the war. I guess they are all trapped in an alternate reality.
All of the above is told in broken English with few complete sentences. The pertinent parts are mostly hinted at. Crap.
"Death cannot stop true love; all it can do is delay it for awhile."
