THE MYSTERY OF THE FLOATING ISLAND

The inhabitants of Rastepappe Island, including the famous detective Archibald, are enjoying a beautiful summer, perfect for relaxation. The premiere of Blaireaussignol's new opera is imminent, but the costumes are nowhere to be found... and that's just the beginning of a series of mysterious disappearances. At the print shop, bolts are missing; at the restaurant, the chef's utensils; at the library, the indispensable ladder... Even Archduke's crown has vanished! This is too much to be mere coincidence. But there are no clues, no leads... until Archibald finally notices an unusual detail: an island, a tiny island, has appeared off the coast of Rastepappe.
