Dark Angel

Series 1 - Episode 1



There are (clearly unintentional) shades of black comedy in this grim two part dramatisation of the [real] life of Victorian serial killer Mary Ann Cotton. Simply because two parts isn’t enough to accommodate comfortably all of Cotton’s bereavements and, later, murders.

So one after the other, with almost indecent haste, her children die then she starts poisoning her unfortunate spouses with arsenic for their life insurance money.

Downton’s Joanne Froggatt plays Cotton and it’s a thankless role as there’s little time for us to get to know Mary before she’s making deadly tea with a dark look on her face, or furiously coupling with a charming layabout who catches her eye or looking scheming in a shawl.

There’s good support from Alun Armstrong as her pub-owning, God-fearing stepfather and the evocation of a horribly hard life by the sea in 19th century north-east England is suitably vivid.


Part one of two. Fact-based period crime drama about serial poisoner Mary Ann Cotton, who raised herself socially and financially through adultery, bigamy, fraud and murder. It is 1857 and 24-year-old Mary Ann returns to Seaham, Co Durham after four years away, having eloped to Cornwall with Billy Mowbray. The couple then move to Sunderland, where Mary Ann begins an affair with miner Joe Nattrass and decides she has had enough of Billy, lacing his tea with arsenic powder. Joanne Froggatt stars, with Jonas Armstrong and Alun Armstrong.
