This is an interesting query because (ഒരു സങ്കീർത്തനം പോലെ) is a famous Malayalam novel by Perumbadavam Sreedharan . It’s a modern retelling of the love story of Dostoevsky and his wife Anna.

However, there is of this book circulating widely, as it is still under copyright protection in India (the author passed away in 2020, but copyright persists for decades). Most "PDF" searches lead to pirated copies.
