You probably shouldn’t ask your reader about the Library Secret Service. Because even if they did know about the LSS, which they totally don’t, they couldn’t tell you. And even if you wanted to know about the LSS’s Very Important Guidelines for keeping library books safe, they would be sworn to secrecy. And by the way, if you think that you happened to see some sort of secret LSS symbol… well… you must be mistaken. Because the Library Secret service doesn’t even exist. 🤞 🤔
