[1][2] Based on the story Sonali Parer Rahashya by Samaresh Basu, the film features child actor Ahijit Ghosh and Indraneil Sengupta in the lead roles.

It boasts of being the first film to feature a tattooed Bengali private detective (Indraneil Sengupta).

Gogol is a fictional child sleuth created by the famous Bengali writer Samaresh Basu.

Though the story, Sonali Parer Rahashya, was initially written in the 1970s, it has been modernized by the crew members to make it more contemporary and interesting to the younger generation.

[1] The film was shot in several places of West Bengal and Orissa, including Kolkata, Tajpur, Puri and Udayagiri and Khandagiri Caves.

In an interview with The Telegraph, director Arindam Dey said, "Detective stories are the most difficult to shoot.

Plus, the haunted house around which Gogol's adventures take place had to be built on the Puri Beach.

Newcomer child actor Ahijit Ghosh managed to get some positive remarks from most critics and reviewers.

[3] The Times of India rated it 3 out of 5 stars and said, "While Indraneil as Ashoke lends credibility to his character – that of an undercover cop – with his personality and body language, Shaheb and Rachna do a good job as Gogol's (child artiste Ahijit) parents.

Some of the scenes such as smugglers discussing their secret plans in the hotel lobby loud enough to be overheard by others is a not-so-good idea.
