Best mystery tv shows ?

[MasterEmile]

Hi guys.
I've been wanting to binge a new series for a long time now but I'm finding it really hard to find a series that I like.
What I like most about a series is a sense of mystery, where you try to gather clues to try to understand a huge mystery surrounding the plot and a huge plot twist at the end wouldn't be that bad.

I LOVED the murder mystery of the mentalist  (that Red John arc was amazing) and my friend ruined pretty little liars for me.
