Diplomatic obligations have overshadowed the writer in him, the Indian High Commissioner to Canada says.
"But then I have always been a diplomat who writes, not the other way round," he adds.
After his debut novel "Q&A" was adapted into the multiple Oscar-winning "Slumdog Millionaire", Swarup has written two more books - "Six Suspects" (in 2008) and "The Accidental Apprentice" (2013).
"I've been in Canada for just over five months and I have been quite busy here as well," he says.

According to Swarup, he is at the moment focused exclusively on developing India-Canada relations.
"But I'm hoping Canada will inspire me eventually. It's a very large and beautiful country."
Asked if there will be a sequel to "Q&A", he says, "I don't really believe in sequels. As long as I have original material, why rehash old characters?"
Swarup, however, has found some time to read.
He is reading books on the history of Canada as also "Plutocrats" by Chrystia Freeland, a former journalist who is now Canada's foreign minister.
