August 1565: When a rival artisan turns up dead outside Ginjiro's brewery, and all the evidence implicates the brewer, master ninja Hiro Hattori and Portuguese Jesuit Father Mateo must find the killer before the magistrate executes Ginjiro and seizes the brewery, leaving his wife and daughter destitute. A missing merchant, a vicious debt collector, and a female moneylender join Ginjiro and the victim's spendthrift son on the suspect list. But with Kyoto on alert in the wake of the shogun's recent death, a rival shinobi on the prowl, and samurai threatening Hiro and Father Mateo at every turn, Ginjiro's life is not the only one in danger. Will Hiro and Father Mateo unravel the clues in time to save Ginjiro's life, or will the shadows gathering over Kyoto consume the detectives as well as the brewer?","forthcoming":false,"isbn13":"9781633885486","publication_date":"20190611","publisher":"Seventh Street Books","slug":"flask-of-the-drunken-master","subtitle":"A Hiro Hattori Novel","title":"Flask of the Drunken Master"},"discovery":{"categories":{"all":[{"bisac_code":"FIC022060","confidence_band":"medium","label":"Historical Mystery","score":0.7314,"source":"bisac_hint_model"},{"bisac_code":"FIC022090","confidence_band":"medium","label":"Private Eye Fiction","score":0.7117,"source":"bisac_hint_model"},{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.7106,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC022060","confidence_band":"medium","label":"Historical Mystery","score":0.7314,"source":"bisac_hint_model"},{"bisac_code":"FIC022090","confidence_band":"medium","label":"Private Eye Fiction","score":0.7117,"source":"bisac_hint_model"},{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.7106,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC014000","confidence_band":"high","label":"Historical Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC022060","confidence_band":"high","label":"Historical Mystery","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC031010","confidence_band":"high","label":"Crime Fiction","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Historical Mystery","score":0.7314,"slug":"historical-mystery"},{"label":"Private Eye Fiction","score":0.7117,"slug":"private-eye-fiction"},{"label":"International Crime Fiction","score":0.7106,"slug":"international-crime-fiction"}],"reader_fit":["For readers drawn to historical murder mysteries with multiple suspects"],"related_lists":[],"series":null,"similar_books":[{"authors":["Susan Spann"],"book_id":"9781633881815","cover_image_url":"https://img.bookfrontier.com/9781633881815.jpg?v=3c05f52dfc3e3c56","score":0.8341,"title":"The Ninja's Daughter","url":"https://bookfrontier.com/books/9781633881815"},{"authors":["Susan Spann"],"book_id":"9781633885448","cover_image_url":"https://img.bookfrontier.com/9781633885448.jpg?v=82470c174607294e","score":0.8287,"title":"Claws of the Cat","url":"https://bookfrontier.com/books/9781633885448"},{"authors":["Susan Spann"],"book_id":"9781633885462","cover_image_url":"https://img.bookfrontier.com/9781633885462.jpg?v=d6e358f88059c5a3","score":0.8229,"title":"Blade of the Samurai","url":"https://bookfrontier.com/books/9781633885462"},{"authors":["Susan Spann"],"book_id":"9781633884151","cover_image_url":"https://img.bookfrontier.com/9781633884151.jpg?v=17ab9c5f2efef0df","score":0.8142,"title":"Trial on Mount Koya","url":"https://bookfrontier.com/books/9781633884151"},{"authors":["Susan Spann"],"book_id":"9781633882775","cover_image_url":"https://img.bookfrontier.com/9781633882775.jpg?v=96c19edbdd48dd51","score":0.8018,"title":"Betrayal at Iga","url":"https://bookfrontier.com/books/9781633882775"},{"authors":["Susan Spann"],"book_id":"9781633885509","cover_image_url":"https://img.bookfrontier.com/9781633885509.jpg?v=4264dab0f93b2f94","score":0.8015,"title":"Ghost of the Bamboo Road","url":"https://bookfrontier.com/books/9781633885509"},{"authors":["Susan Spann"],"book_id":"9781645060451","cover_image_url":"https://img.bookfrontier.com/9781645060451.jpg?v=c787618b58fd2812","score":0.7984,"title":"Fires of Edo","url":"https://bookfrontier.com/books/9781645060451"},{"authors":["Jonelle Patrick"],"book_id":"9781645060222","cover_image_url":"https://img.bookfrontier.com/9781645060222.jpg?v=150a021235b0021e","score":0.697,"title":"The Last Tea Bowl Thief","url":"https://bookfrontier.com/books/9781645060222"}],"topics":[{"evidence_refs":["keyword:kyoto historical mystery"],"label":"Historical","score":0.1137,"slug":"historical"},{"evidence_refs":["keyword:kyoto historical mystery"],"label":"Mystery","score":0.0915,"slug":"mystery"},{"evidence_refs":["keyword:feudal japan suspense"],"label":"Suspense","score":0.0431,"slug":"suspense"}],"what_you_get":["Themes: Murder investigation, Threats to family livelihood, Political uncertainty.","Pacing: fast, momentum-driven storytelling.","Story elements: Detective partnership, Multiple suspects."]},"llm_signals":{"confidence":0.91,"pacing":"fast","reader_fit":["For readers drawn to historical murder mysteries with multiple suspects"],"themes":["Murder investigation","Threats to family livelihood","Political uncertainty"],"tropes":["Detective partnership","Multiple suspects"]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":7,"goodreads_ratings_count":302,"goodreads_reviews_count":59,"quality_score":0.8978}}
