Two hunters, one cold, deliberate and highly efficient and the other, a strong, athletic man with a wife, two children and a counselling job... one of them is a serial killer and one is a cop. Seasons 1 and 2 are outstanding, but you might want to give the third season a pass.
Based on the true story of Grace Marks, a housemaid and immigrant from Ireland who was imprisoned in 1843, perhaps wrongly, for the murder of her employer Thomas Kinnear. Grace claims to have no memory of the murder yet the facts are irrefutable. A decade after, Dr. Simon Jordan tries to help Grace recall her past.
