C.B. Strike

While visiting his family in Cornwall, Strike is approached by Anna Phipps, who seeks his help finding her mother who went missing in 1974.

While Strike deals with a difficult family matter, a rogue Robin locates and goes after two key -- and potentially dangerous -- suspects.

With a narrowing list of unreachable suspects, Strike and Robin utilize their resources to contact notorious serial killer, Dennis Creed.

As Strike and Robin inch closer to the truth of Margot's disappearance, will they finally bring closure to the past?
