Detective Esa Khattak is in the midst of his evening prayers when he receives a phone call asking that he and his partner Detective Rachel Getty look into the death of a local man who has fallen off a cliff. At first Christopher Drayton's death - which looks like an accident - doesn't seem to warrant a police investigation, especially not from Khattak and Rachel's team, which handles minority-sensitive cases.

For months, INSET has been investigating a local terrorist cell that is planning an attack on New Year's Day. INSET had an informant, Mohsin Dar, undercover inside the cell. But now, just weeks before the attack, Mohsin has been murdered at the group's training camp deep in the woods. INSET wants Khattak to give the appearance of investigating Mohsin's death and then to bury the lead. They can't risk exposing their operation or Mohsin's role in it.
