It seems the boys can get nothing right: Their teacher's fiftieth birthday is long past (they should have done their math homework); the servant they bought as a present for his birthday isn't just your run-of-the-mill Gaul slave but a courier running for his life; and, to top it all off, the message he's carrying requests the assassination of a Roman senator—the father of one of the boys.","forthcoming":false,"isbn13":"9780152162689","publication_date":"20021101","publisher":"HarperCollins","slug":"mystery-of-the-roman-ransom","subtitle":"","title":"Mystery of the Roman Ransom"},"discovery":{"categories":{"all":[{"bisac_code":"JUV016020","confidence_band":"high","label":"Ancient Civilizations","score":0.8101,"source":"bisac_hint_model"},{"bisac_code":"JUV030050","confidence_band":"medium","label":"Stories Set in Europe","score":0.78,"source":"bisac_hint_model"},{"bisac_code":"JUV016040","confidence_band":"medium","label":"Historical Europe","score":0.7794,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JUV016020","confidence_band":"high","label":"Ancient Civilizations","score":0.8101,"source":"bisac_hint_model"},{"bisac_code":"JUV030050","confidence_band":"medium","label":"Stories Set in Europe","score":0.78,"source":"bisac_hint_model"},{"bisac_code":"JUV016040","confidence_band":"medium","label":"Historical Europe","score":0.7794,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JUV004010","confidence_band":"high","label":"European Biographies","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV005000","confidence_band":"high","label":"Boys & Men","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV007000","confidence_band":"high","label":"The Classics","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV014000","confidence_band":"high","label":"Girls & Young Women","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV016020","confidence_band":"high","label":"Ancient Civilizations","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV016040","confidence_band":"high","label":"Historical Europe","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV016070","confidence_band":"high","label":"Medieval Tales","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV016100","confidence_band":"high","label":"Renaissance Stories","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Ancient Civilizations","score":0.8101,"slug":"ancient-civilizations"},{"label":"Stories Set in Europe","score":0.78,"slug":"stories-set-in-europe"},{"label":"Historical Europe","score":0.7794,"slug":"historical-europe"}],"reader_fit":["Good for readers interested in historical mysteries set in Ancient Rome"],"related_lists":[],"series":null,"similar_books":[{"authors":["Russell Punter"],"book_id":"9781805078975","cover_image_url":"https://img.bookfrontier.com/9781805078975.jpg?v=0525618d0965b3e7","score":0.7438,"title":"Mummy Mystery","url":"https://bookfrontier.com/books/9781805078975"},{"authors":["George Shannon"],"book_id":"9780380732616","cover_image_url":"https://img.bookfrontier.com/9780380732616.jpg?v=1747343741e801da","score":0.7112,"title":"More Stories to Solve","url":"https://bookfrontier.com/books/9780380732616"},{"authors":["Ruta Sepetys","Steve Sheinkin"],"book_id":"9780593527559","cover_image_url":"https://img.bookfrontier.com/9780593527559.jpg?v=a40c484c9d9b3606","score":0.7082,"title":"The Bletchley Riddle","url":"https://bookfrontier.com/books/9780593527559"},{"authors":["A.
