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":"OUATB","offers":[{"title":"Default Title","offer_id":48203703288063,"sku":"*R0049297*","price":4.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0487\/5550\/7364\/files\/14342823482347.jpg?v=1771616275","url":"https:\/\/shop.onceuponatimebooks.com\/products\/hardy-boys-19-the-disappearing-floor","provider":"Once Upon a Time Books AR","version":"1.0","type":"link"}
