Sharadindu Bandyopadhyay was born in March 1899 to Tara Bhushan and Bijaliprabha Bandyopadhyay at his maternal grandparents' home in Jaunpur, United Provinces of Agra and Oudh, British India (now in Uttar Pradesh, India). The Bandyopadhyay family's residence was at Purnia, Bihar, India, his father Tara Bhushan’s workplace, but the family originally hailed from Baranagar, North Kolkata, West Bengal, India. He completed his matriculation in 1915 at a school in Munger. He wrote his first story, "Pretpuri," a Boroda story, when he was only 15 years old. After matriculation, he joined Vidyasagar College, Kolkata. Sisir Bhaduri, the doyen of Bengali stages, was his English professor there. After completing graduation, he went on to study law in Patna. He was only thirty years old when he gave up his practice and started working as a writer. He received a call from the Mumbai film industry as a scriptwriter. He left Mumbai in 1941 and settled permanently in Pune, where he breathed his last in the early 70s. The 1960s and 1970s saw enormous popularity for his writings. He has written numerous historical novels, long stories, short stories, dramas, and last but not least, the iconic Byomkesh Bakshi. Byomkesh Bakshi is a detective who calls himself Satyanweshi, or the Truth-Seeker. He is known for his proficiency with observation, logical reasoning, and forensic science, which he uses to solve complicated cases, usually murders.
These stories were written from 1932 to 1970, a remarkably long period. More than 35 Byomkesh thrillers were written in the form of long short stories and novels.
