The novel tells the story of Nick Miller, a newly recruited police officer who lives with his rich brother but who will not take part in his brother's business. Miller is on the trail of Ben Garvald, a man who has just been released from prison after completing a nine-year sentence there.

Jean also has a note from Ben to her sister when he was in prison telling her that he is coming back. This results in Nick hunting for Ben from scratch through his friends.
