Sharadindu Bandhopadhay's most well known character Byomkesh Bakshi first appeared as a character in the story Satyanweshi (The Inquisitor). The story is set in 1931 in the Chinabazar area of Kolkata where a 'non government detective' Byomkesh Bakshi, owing to the permission from the police commissioner, starts living in a mess in that area under the pseudonym of Atul Chandra Mitra to probe a series of murders. Most of the stories are written by Sharadindu under the pen name of Ajit who is said to have met Byomkesh in the mess at Chinabazar. Byomkesh Bakshi is described in Satyanweshi as "a man of twenty-three or twenty-four years of age who looked well educated." Later in the story it comes to be known that Byomkesh lives on a three-story rented house at Harrison Road.
