"An Astrologer's Day" by R.K. Narayan tells the story of a man who pretends to be an astrologer and encounters a stranger he once wronged. Set in a bustling market, the astrologer uses his skills of observation and manipulation to maintain his facade. When a man named Guru Nayak, whom the astrologer once tried to kill, confronts him, the astrologer cleverly uses his knowledge to satisfy Nayak's questions and avert suspicion. Through their interaction, the astrologer learns of Nayak's quest for revenge and is able to provide him with false yet convincing answers. After Nayak departs, the astrologer reveals to his wife that he was the one who pushed Nayak down the well years ago, feeling a sense of relief and redemption now that Nayak's revenge has been thwarted.
