All murder mysteries have surprises, complications and a smart detective (or maybe lucky). What distinguishes the excellent ones from the good ones is not just the plot, but such things as characterization, acting, dialogue, cinematography, and even lighting. Netflix has made this movie available.
"Raat Akeli Hai" (2020) offers a lot of what you might expect, but goes beyond. Political machinations are fascinating, and in this movie it is not just that powerful politicians cast their influence, but all the characters are secretive and manipulative. An arrogant cop is the focus of their anger.
The family head, a powerful political figure marries a woman everyone declares a whore. Then late the same evening he is brutally murdered. It is obvious to most that the whore bride is guilty and others including the cop feel a lover is involved.
The phrase "the world is a cruel place" is first used in a flashback five years previous when by a coincidence the cop had met the whore on a train ride and said it to her. After he questions her after the murder she repeats the same phrase back to him to acknowledge she remembered. It is used one last time, but you will have to see the movie to appreciate the context.
Details and aim, matter and that stems from producers who transform the story idea into a viable film.

The background score was done by Karan Kulkarni and was effective at quietly stirring anxiety.

(2015) and "Manto" (2018). There were no Bollywood dance routines that turn off some Western sensibilities.
The cinematography by Pankaj Kumar was another mood setting element. Indoor shots and night time were dark. He has worked on "Ship of Theseus" (2012), "Haider" (2014), "Talvar" (2015) and "Rangoon" (2017). He contributed to the story for "Ship of Theseus" 2012 and won awards for it.

The stellar cast was led by Nawazuddin Siddiqui. The son of a farmer he became a chemist. A long time playing minor roles before being recognized as an exceptional actor. He played an aggressive obnoxious policeman in "Kahanni" (2012) blowing smoke in the face of a pregnant woman. He played an obsequious role in "The Lunchbox" (2013).

Supporting roles are all realistically done. If you like murder mysteries this is one that stands well for comparisons.
Note: Bolded movie titles are of ones I have seen although not necessarily recommend, but indicates some development of the artist. Did not repeat the bolding when subsequent crew worked on the same film.
