Live Poll: IMDb Poll Board Favorite Murder-Mystery Series

Allow me to suggest some relevant keywords to help people find their favorites:

whodunit (522 titles)

whodunnit-mystery (137 titles)
who-done-it (11 titles)

mystery-murderer (6 titles)

murder-mystery (679 titles)

Many if not most of these keywords should be merged. I am working on that. 

My suggestion:

 Twin Peaks (1990–1991)

My pick: Poirot (1989-2013)

Hannibal (2013–2015)

Honorable mention to (only one season):

Only Murders in the Building (2021– )

True Detective S1

the mentalist

Murder, She Wrote

Second place would be Columbo

Prison Break 💯💯

P.S.: Also 10/10, Homeland & The Other Me🤝🤝🤝

Elite, But I like it at the beginning of the season until the third season, the current season is too boring to follow this series.
