The trail leads to the outskirts of the Hardys' home town and to a weirdly guarded mansion on the old Perth estate. With their pal Chet Morton, the brothers must tackle the mystery of the mansion heir's sudden death. A disappearing floor, a huge, savage-looking, hound, a galloping ghost, and a college professor's startling invention are just a few of the strange elements that complicate the boys' efforts to solve both mysteries.","brand":"World of Books ","offers":[{"title":"Default Title","offer_id":53767621771537,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780448089195.jpg?v=1783937835","url":"https:\/\/www.worldofbooks.com\/products\/books-the-hardy-boys-19-the-disappearing-floor-by-franklin-w-dixon","provider":"World of Books ","version":"1.0","type":"link"}
