In the evening it was time for Byomkesh and Ajit to pursue the mysterious "Pother kanta" advertiser. Ajit was sent out in disguise and Byomkesh followed him but maintained a safe distance. Ajit arrived at the designated spot and waited but nothing happened. On his way back he was accosted by a beggar who handed him an envelope. As Ajit was looking at its contents, the beggar left the scene. Ajit them took a roundabout way on his way back home. Byomkesh remarked that inside the envelope was the letter he had been expecting but since Ajit had been searching his own pockets incessantly, the advertiser had waited until he left the scene. did Inside was a letter with the message that when translated would read, "Who is your Thorn of the road? What is his name and address? Clearly state what you want. Next time we'll meet at midnight. Please come alone to the Khiddirpore Road and walk along it. A man on a bicycle will come and take your written responses from you."
