Byomkesh solves the mystery by timing the church bells against a witness’s testimony, proving the killer entered the room after Sukumar had returned home. The real culprit is revealed as Phonibhushan, the disabled nephew who felt like a "pity case" and sought to frame Sukumar out of resentment . Phani used the delinquent Makhan to obtain chloroform and stole Satyabati’s needle to commit the perfect crime, even marking Sukumar’s book with a red pencil found in his own possession. Realizing the game is up, Phani commits suicide by leaping from the roof, leaving behind a written confession.The season ends with Byomkesh, Ajit, and a new family member—Satyabati—sharing a meal until a frantic Habul arrives with a new case.
