Angel of Death (2020-2024)

The Polish series Szadz, or Angel of Death, began airing in 2020, but we didn't catch wind of it until well into its fourth season! More on that later... The series follows police detective Agnieszka Polkowska (Aleksandra Poplawska), first as she investigates the murder of a young girl whose death appears to be linked to an obscure ancient ritual. Meanwhile, we also begin to follow a jovial professor in the town where the girl's body was discovered, Piotr Wolnicki (Maciej Stuhr). Though he seems the model of a charming and smart academic, he's also the serial killer Agnieszka is searching for! It's not really a spoiler, since you find out pretty early in the first season that this is the dynamic, but it took until season four of the series to finally get some skin in the game when—spoilers this time—Maciej Stuhr goes ass out while taking a shower in prison!
