Why Women Kill was indeed cool series, although I liked the first season a lot more than the second one, which kinda highlighted absurdity for the sake of comedy and didn't do it very well.
I also loved watching the old Poirot series and first two seasons of Sherlock were nice. Lucifer and Brooklyn 9-9 also had really cool moments. So help me Todd and Suits were also interesting, although there's more of an emphasis on lawyers rather then detective work, but still there's a good bit of a mystery here and there. I've watched Lie to me and Mentalist, and Colombo was an interesting twist on your usual "whodunnit" to "how he's gonna prove it".
Ah, good times.
