Clark has to interview a murderer up for parole. The case has haunted him since he found the files as a child and he opportunistically used his father's name to access the first interview. The murderer persuades Clark to investigate the mine which was the crime scene. The secrets and twists Clark discovers are as complicated and unpredictable as the network of abandoned iron mines in Harriman St. Park. Clark is caught in a three way trap and must choose between preserving his father's reputation, possibly letting a child murderer go free, and keeping the job he spent his life perfecting.
