In literature, "investigate" is employed in a variety of ways that reflect both literal and metaphorical quests for truth and understanding. It often denotes a methodical inquiry into mysteries or crimes, as seen in detective narratives where characters seek to uncover hidden truths [1][2][3]. At the same time, the word carries an abstract, philosophical weight in works that examine the nature of experience or morality, inviting readers to probe the deeper significance of phenomena [4][5][6]. Whether the inquiry is physical, as in a search for factual evidence, or mental, as in a meditation on ideas, the term underscores a persistent human desire to unravel complexities and grasp the essence of things [7][8][9].
