In which work would you find the character Ishmael?

Ishmael is the narrator and one of the central characters in Herman Melville's "Moby-Dick." This novel, published in 1851, is a complex tale of obsession and revenge, primarily focusing on Captain Ahab's pursuit of the titular white whale. Ishmael serves as the voice that guides the readers through the narrative, providing insight into the themes of existentialism, fate, and humanity's relationship with nature. His character begins the story by reflecting on his desire to go to sea, which sets the stage for the epic journey that follows.

In contrast, the other works listed do not feature a character named Ishmael. "The Great Gatsby" by F. Scott Fitzgerald revolves around Jay Gatsby and his obsession with Daisy Buchanan. "Life of Pi" by Yann Martel follows Pi Patel's survival story on a lifeboat with a Bengal tiger. "To Kill a Mockingbird" by Harper Lee centers on Scout Finch and her experiences in the racially charged atmosphere of the American South. Therefore, the presence of Ishmael is distinctly tied to "Moby-Dick," making it the correct answer.
