Good character improvisation, nice script and relatively good cinematography. But the original flavor of Byomkesh Bakshi is missing. Lengthy story out flow is another big problem. Jishu U Sengupta is as usual good. Saswata Chatterjee proved his talents again. The story could be more pact up. In comparison to other Byomkesh movies of this banner, this one is faded a little away. I rate Anjan Dutta directed "Byomkesh O Agniban" 3/5
