What happens

Goodwin, O'Keefe, and Huldricksson set up a vigil at the moon door on Nan-Tauach, using Becquerel ray-condensers to focus moonlight on the stone bosses. The door opens, but Olaf is pulled inside; O'Keefe fights off an attacker—revealed to be the Russian Marakinoff—and both he and Goodwin are trapped when the door closes. Goodwin reflects on the mystery and danger, and the chapter includes Da Costa's confession about transporting Marakinoff to Ponape, as well as the group's tense journey through the silent ruins to the moon door.
