Chowdhury Barir Rahasya by Abhirup Sarkar [Hardcover]

"Once a scion of a prestigious family, Aditya Majumdar, the hero of this story, found himself in a difficult situation after his father's death and had to live in a modest mess house. Unlike Byomkesh, who was an amateur detective by choice, Aditya became a private investigator purely out of necessity to make ends meet.

The story begins with a phone call from a woman named Sohini Choudhury. This wealthy woman suspects that someone is trying to kill her mother, Mandakini Choudhury, as there have been three attempts on her life, and she narrowly escaped each time. To understand the case better, we are introduced to Mandakini's background. Mandakini was a former popular actress and is now the owner of Choudhury Enterprises. Sohini, who approaches Aditya with the case, is Mandakini's daughter from her first marriage to Nilanjan Maitra. After divorcing her first husband, a theater artist, Mandakini remarried Subir Choudhury, the head of Choudhury Enterprises. The stepfather has now passed away. There is also a daughter from the previous marriage, Shankhamala, and a son, Shankdeep. Shankhamala is calm, but her husband, Subrata Sen, is a bit greedy. Shankdeep is a rebellious son. There are suspicions surrounding several individuals.

During the investigation, two goons attack Aditya, which deepens the suspicion. Who is pulling the strings from behind the scenes? Is a new danger approaching? All the answers will come at the very end, with a major twist and a rather tragic ending."
