It is 1866, and Walter Moody has come to make his fortune upon the New Zealand goldfields. On the stormy night of his arrival, he stumbles across a tense gathering of twelve local men, who have met in secret to discuss a series of unsolved crimes. A wealthy man has vanished, a prostitute has tried to end her life, and an enormous fortune has been discovered in the home of a luckless drunk. Moody is soon drawn into the mystery: a network of fates and fortunes that is as complex and exquisitely patterned as the night sky.
