Case of Discovery comprises a lecture, which was delivered by Dr. Nishikant Chattopadhyaye in 1904, in Hyderabad. Well-versed in several languages, he was a true seeker in the real sense of the word. He studied religion and its related disciplines in detail. Finally he became fully convinced of the veracity of Islam. Having found the answer to his quests he embraced the true faith. After his acceptance, he delivered a lecture on the 26th August 1904, at the historic Fateh Maidan in Hyderabad. That same year Luzac & Sons printed this lecture, one copy of which is still extant in the British Museum in London. It was later reprinted in 1971 from a copy found by Mr. Hasanuddin Ahmad of Hyderabad in the library of Mirza Abul Fazl, also of Hyderabad.
