Dark Angel
Part 1
S1 E101:
This is the story of a troubled woman drawn ever deeper into a career of casual murder, while her loved ones and friends, who were also her victims, never suspected a thing. Golden Globe-winner Joanne Froggatt (Downton Abbey) portrays the notorious Victorian poisoner Mary Ann Cotton, a child of the northeast England coal fields who dreamed of escaping the hard life of a miner's family.
