Ah, I do enjoy a good secret tucked between the pages. In many classics the authors or editors have slipped in acrostics, hidden initials, even subtle punctuation tricks that only reveal a message when you read carefully or arrange the books in a certain way. It’s like a quiet puzzle that rewards the patient reader, and I find myself arranging the shelves just so I can keep those clues at hand. If you’re looking for one, I can point you to a few classics that are known for their covert messages; just let me know which era or genre intrigues you.
