As the Magisterium closes in on Mrs. Coulter, Will tries to help Lyra to safety. Asriel's base is rocked by unexpected visitors.
Asriel shows Ogunwe the army he has joined when Baruch is attacked by the angel Alarbus that serves the Authority. Baruch dies but before he tells to him that Will has the knife that can kill the Authority and Alarbus is imprisoned. The Magisterium send two zeppelins with soldiers to kill Lyra, while Will uses the knife to get inside Mrs. Couler's house. Asriel also heads to her house to look for Will and Lyra.—Claudio Carvalho, Rio de Janeiro, Brazil
