We were a long way into the film when I thought I wasn’t going to “get it”. By intermission I had figured the story out enough to follow what was going on. We were nearing the end of the film and I thought I would go home without knowing who the spy was. Fortunately that didn’t happen, but even on the drive home Pat and I were questioning one another about what we thought had happened. There are still a lot of holes in my understanding of the story and I hope that by reading the book I will figure it out.
