Sixty years later, Catherine Bailey became the first historian given access. What she discovered was a mystery: The Duke had painstakingly erased three periods of his life from all family records—but why? As Bailey uncovers the answers, she also provides an intimate portrait of the very top of British society in the turbulent days leading up to World War I.","forthcoming":false,"isbn13":"9780143124733","publication_date":"20131231","publisher":"Penguin Publishing Group","slug":"the-secret-rooms","subtitle":"A True Story of a Haunted Castle, a Plotting Duchess, and a Family Secret","title":"The Secret Rooms"},"discovery":{"categories":{"all":[{"bisac_code":"BIO006000","confidence_band":"high","label":"Lives in History","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS015000","confidence_band":"high","label":"British History","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS054000","confidence_band":"high","label":"Social History","score":1,"source":"onix_publisher_code"}],"hint":[],"publisher":[{"bisac_code":"BIO006000","confidence_band":"high","label":"Lives in History","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS015000","confidence_band":"high","label":"British History","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS054000","confidence_band":"high","label":"Social History","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Lives in History","score":1,"slug":"lives-in-history"},{"label":"British History","score":1,"slug":"british-history"},{"label":"Social History","score":1,"slug":"social-history"}],"reader_fit":["Good for readers who enjoy Lives in History","Good for readers interested in book club","Good for readers who enjoy Lives in History and British History."],"related_lists":[],"series":null,"similar_books":[{"authors":["Leslie Carroll"],"book_id":"9780451232212","cover_image_url":"https://img.bookfrontier.com/9780451232212.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":14.7917,"title":"Royal Pains","url":"https://bookfrontier.com/books/9780451232212"},{"authors":["Greg Melville"],"book_id":"9781419754869","cover_image_url":"https://img.bookfrontier.com/9781419754869.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":11.3739,"title":"Over My Dead Body","url":"https://bookfrontier.com/books/9781419754869"},{"authors":["Deborah Taffa","Deborah Jackson Taffa"],"book_id":"9780063288522","cover_image_url":"https://img.bookfrontier.com/9780063288522.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":11.2644,"title":"Whiskey Tender","url":"https://bookfrontier.com/books/9780063288522"},{"authors":["Amos Oz","Nicholas de Lange"],"book_id":"9780156032520","cover_image_url":"https://img.bookfrontier.com/9780156032520.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":11.1836,"title":"A Tale of Love and Darkness","url":"https://bookfrontier.com/books/9780156032520"},{"authors":["Roy Porter"],"book_id":"9780140138191","cover_image_url":"https://img.bookfrontier.com/9780140138191.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":11.0665,"title":"English Society in the 18th Century","url":"https://bookfrontier.com/books/9780140138191"},{"authors":["James Hawes"],"book_id":"9781615198146","cover_image_url":"https://img.bookfrontier.com/9781615198146.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":10.3291,"title":"The Shortest History of England","url":"https://bookfrontier.com/books/9781615198146"},{"authors":["Shashi Tharoor","Tantor Audio"],"book_id":"9781947534308","cover_image_url":"https://img.bookfrontier.com/9781947534308.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":10.2672,"title":"Inglorious Empire","url":"https://bookfrontier.com/books/9781947534308"},{"authors":["Jon Meacham"],"book_id":"9780399589829","cover_image_url":"https://img.bookfrontier.com/9780399589829.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":10.2078,"title":"The Soul of America","url":"https://bookfrontier.com/books/9780399589829"}],"topics":[{"evidence_refs":["keyword:british history"],"label":"History","score":0.9238,"slug":"history"},{"evidence_refs":["keyword:family"],"label":"Family","score":0.162,"slug":"family"},{"evidence_refs":["phrase_map_match"],"label":"Book Club","score":0.0914,"slug":"book-club"},{"evidence_refs":["keyword:british history"],"label":"British","score":0.0475,"slug":"british"},{"evidence_refs":["keyword:history buff gifts"],"label":"Buff","score":0.0434,"slug":"buff"}],"what_you_get":["Themes: History, Family, Book Club.","Reading lane: Lives in History and British History.","Publisher: Penguin Publishing Group."]},"llm_signals":null,"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":false,"similarity_seed":true},"stats":{"amazon_ratings_count":1999,"goodreads_ratings_count":5776,"goodreads_reviews_count":948,"quality_score":0.9722}}
