'The Sinner' Season 2: The mystery intensifies as the detective deals with a child killer while sifting through his own past
When detectives Heather and Ambrose set out to unravel the hidden mystery behind a boy who poisoned and killed his parents, they discover truths which will take them back to their own moments of trauma. Natalie Paul's Heather Novack, the apparent assistant of Bill Pullman's Detective Harry Ambrose, is a woman as damaged as her mentor. When it comes to interpreting clues in order to find out the answer to the question "whydunnit" instead of "whodunnit", the two detectives empathize with their subjects.
Just as season 1 of 'The Sinner' treated Ambrose's story like a foil to Cora's tale of trauma and suspense, Heather's story is yet to be explored in its wholeness in Season 2. When talking about the basic connection between the two characters, Ambrose and Heather, Paul said, "It becomes this unlikely friendship or team that develops between Heather and Ambrose...They actually both have their own demons or sins or whatever that they are carrying. ... That becomes a point of suspicion between the two. We're definitely a team, but I'm like, 'Wait. Who is this guy? What is he hiding? Why did he leave our hometown?'"
