Who is man math a Nath Dutt? This Question starts haunting bibek Debroy when he finds that name imprinted on the translations of almost all ancient texts that he too wants to translate from Sanskrit text into English. While multiple translations are not uncommon, what were the chances of two translators invariably choosing the same set of texts? It was almost like man math a Nath Dutt had left a trail for bibek Debroy to follow.

Gathering material and sifting through clues, following various leads and discarding some, Debroy pieces together a jigsaw puzzle to reveal a picture of the prolific translator man math a Nath duty and of nineteenth-century Calcutta.
