The search for a valuable scroll leads Feluda and his friends to a strange cast of characters, and perhaps the most chilling case Feluda has ever been faced with. For among D.G. Sen, the collector of scrolls, his son Mahim, his secretary Nishit, the wildlife photographer Bilas Majumdar and the astrologer Laxman Bhattacharya, there is a cold-blooded criminal, and he must be stopped before it is too late. This is the 11th in the Puffin series of Feluda's 12 greatest adventures.

Satyajit Ray (1921-92) was one of the greatest film-makers of his time. In 1992, he was awarded the Oscar for Lifetime Achievement by the Academy of Motion Picture Arts and Sciences. In the same year he was also honoured with the Bharat Ratna.

Ray was also a writer of repute, and his short stories, novellas, poems and articles, written in Bengali, have been immensely popular. He has published several books in Bengali, most of which became bestsellers. He is also the author of the famous Feluda stories, the translations of which are available in Penguin.
