A Good Girl’s Guide to Murder, a series of books written by Holly Jackson, just got a BBC adaptation, and it might give people the Nancy Drew vibes, but the show is a dark take on people and how their mind works. The show starts as an innocent investigation into a five-year-old closed case. As it becomes sinister, many disturbing revelations about people emerge. The show brings up the subject of how human beings can carry out despicable acts in the name of love and self-preservation. It also showcased the fact that we as humans are also capable of keeping a secret for way too long until the guilt catches up or someone eventually finds out what we did. There are multiple characters that act this way, and one of them is Dan Da Silva, the brother of Andie’s best friend Nat Da Silva, who was working with the local police.
