Arto Nyberg - Season 18

To the casual observer, there's nothing remarkable about Sylvia.  An intelligent, confident woman, Sylvia tends to keep quiet about her formidable linguistic abilities, impressive knowledge of weaponry, and skills as a markswoman. Questions about her professional life are met with bland answers about an unspectacular career in the Civil Service.  Which is only very slightly true – because until recently, Sylvia was a high-ranking British spy. 

20/20 continues to combine hard-hitting investigative reports, newsmaker interviews and compelling human interest and feature stories.

The Drop follows Wanda and Leon (from the original Snowfall series), who are now fighting to reinvent themselves in '90s Los Angeles, where the fallout from the crack epidemic is fueling a new game: the rise of West Coast rap.

In the midst of an international crisis, a career diplomat lands in a high-profile job she's unsuited for, with tectonic implications for her marriage and her political future.

In Boston Blue, NYPD Detective Danny Reagan takes a position with Boston PD. Once in Boston, he is paired with Detective Lena Silver, the eldest daughter of a prominent law enforcement family.
