Lyra Belacqua travels to London with Mrs. Marisa Coulter to be her assistant. They go to the shopping, have lunch together, and they seem to be getting along. However, when Lyra sees the Father MacPhail in Coulter's apartment, she suspects of Marisa and decides to snoop her office. Lyra continues to know how to handle the alethiometer that she received from the Master of the Jordan College. Meanwhile, the leaders of the gyptians decide to attack the Gobblers, but the kidnapped children have been moved. Carlo meets a man called Thomas to seek out a man called Grumman in the other world. Marisa gives a party and Lyra meets a journalist that tells her that Marisa is the head of the Gobblers. Lyra decides to flee from the apartment and while sleeping on the streets, she is kidnapped.
"The Idea of North" is a great episode of "His Dark Materials", with revelations being disclosed. Maybe the truth about Mrs. Coulter is the most important since Lyra was liking her despite the feelings of Pan for Marisa. Carlo Boreal shows that he is a very cruel man. The conclusion of the episode is a cliffhanger that the viewers need to wait for the next episode. My vote is eight.
Title (Brazil): "The Idea of North"
