Would you like me to ruin it for you?Broadchurch. Been out a few years but Netflix recommended it to me now that I've ended my relationship with them.
British mystery - boy's body is found on the beach and the investigation is assigned to a quirky investigator new to the department and town. Secrets are being uncovered about the townspeople right and left - every episode ends on a "dammit now I have to watch the next episode immediately" and so far I suspect everyone. Plus I want fish and chips so bad I can't see straight.
Great watch so far - only three seasons - 8 episodes each season and it reaches a conclusion in the last season that is supposed to make me cry. Bloody hell it might have been his best friend. Or Betty who's really Elaine. Or Jack the child predator. Or the Vicar.
