Erica's husband, Detective Patrik Hedstrom, has his worst suspicions confirmed as the mind-games aimed at Christian and those around him become a disturbing reality. But, with the victims themselves concealing evidence, the investigation is going nowhere. Is their silence driven by fear or guilt? And what is the secret they would rather die to protect than live to see revealed?
