If that really was the final episode, it was a bit of a letdown. There was sort of a resolution with Foyle going to America, but nothing like the ending of "All Clear." Sam is getting married to Andrew, but Milner isn't involved in the episode. It didn't feel like a culmination at all, which would be hard to do since the war is over.
The case this week had more pathos than last week's episode without all the blatant moralizing under a suspect pretense. Members of the British Free Corp come back to England. One is arrested and the other is welcomed as a hero after passing on information to the British. Foyle unravels the mystery and discovers that their roles were actually switched.
Score: 8.8/10
