Suppose Harry Potter and the Sorcerer's Stone is the first book in the Harry Potter series, written by J.K. Rowling. It was published in 1997 and follows the story of a young wizard, Harry Potter, as he attends Hogwarts School of Witchcraft and Wizardry.
Can we infer that "The Sorcerer's Stone is the last book in the Harry Potter series"? Yes, no, or maybe?
