The Lost Red Pencil

Overview

The investigation into Sukumar, a medical student with the anatomical knowledge to kill with a needle, intensifies when Byomkesh finds a marked-up copy of Gray’s Anatomy in his room. However, the red pencil used to mark the murder method is missing. To clear the innocent, Byomkesh and Ajit venture into the city’s red-light district to track down Motilal. There, a woman named Dalim provides Motilal with a solid alibi, confirming he was unconscious from drinking during the murder. Vidhubabu remains convinced Sukumar is the killer after "finding" a new will and chloroform in his trunk, but Byomkesh suspects the evidence was planted. He meets a desperate Satyabati in secret, who confesses she saw a shadow she believed was her brother entering the room at midnight.
