FAMOUS FIVE-Five go to Smugglers Top-4th book in a series of 21!

Famous Five book-Five go to Smugglers Top-4th book in a series of 21. These awesome books are straight from my childhood and have been around forever. They are easy to read and I always found them thoroughly enjoyable. This is a British edition from what looks like 1982. There is a barely legible name on the first page but considering it’s age it’s in very good condition! Thanks for looking and all the best!
