That Roy would adapt Bram Stoker's Dracula into Bishalgarer Dushshashan, Arthur Conan Doyle's The Hound of the Baskervilles into Nishachari Bibhishika and Agatha Christie's Ten Little Niggers into Haradhaner Deep attest to his conscious following of Western sleuth writings in order to make something Indian - and therefore post-colonial - out of them".
Roy's adaptation of Bram Stoker's Dracula as Bishalgarer Dushshashan, Arthur Conan Doyle's The Hound of the Baskervilles as Nishachari Bibhishika, and Agatha Christie's Ten Little Niggers as Haradhaner Deep indicates his intention to blend Western detective stories with Indian elements to produce a post-colonial narrative.
