The series stars Rajit Kapur and K. K. Raina as Byomkesh Bakshi and Ajit Kumar Banerjee respectively.

[2] It was re-telecast on DD National in 2020 during the lockdown of 21 days due to coronavirus.

[3] Byomkesh Bakshi is a Bengali Detective and a truth seeker who takes on spine-chilling cases with his friend Ajit Kumar Banerjee.

Byomkesh identifies himself as Satyanweshi meaning 'truth seeker' rather than a detective.

He stands out from other legendary detectives like Poirot or Holmes because he is more concerned with truth than with law as evidenced from his cases where he lets the perpetrator die by manipulating the circumstances using their own methods as a redemption and deliverance of justice for the victim in absence of evidence as in Balak Jasoos, Ret Ka Daldal, and a few other cases.
