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":"Penguin Young Readers Group","offers":[{"title":"Used - good","offer_id":53251353805142,"sku":"9780448089195-G","price":2.89,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9780448089195_1_da76408d-a5ec-4b9b-b494-9a5b4d986565.jpg?v=1777919866","url":"https:\/\/www.momoxbooks.com\/products\/dixon-franklin-w-the-disappearing-floor-9780448089195","provider":"momoxbooks","version":"1.0","type":"link"}
