An apparent lovers’ suicide. And a pair of detectives with a nagging suspicion that the pieces don’t add up. Can you solve one of the most astonishing literary puzzles ever written? “An irresistible Hitchcockian gem: a fiendishly plotted crime novel told in crisp, elegant prose.”—Paula Hawkins, author of The Girl on the Train In a rocky cove at Hakata Bay, the bodies of a young and beautiful couple are discovered. Standing on the cold beach, the police see nothing to investigate: The flush of the couple’s cheeks and the empty juice bottle speak clearly of cyanide, of a lovers’ suicide. But in the eyes of two men, senior detective Torigai Jutaro and Kiichi Mihara, a young gun from Tokyo, something is not quite right. Together, they begin to pick at the knot of a unique and calculated crime. Now widely available in English for the first time, Tokyo Express is celebrated around the world as Seichō Matsumoto’s masterpiece.","forthcoming":false,"isbn13":"9780593979044","publication_date":"20251014","publisher":"Random House Publishing Group","slug":"tokyo-express","subtitle":"A Novel","title":"Tokyo Express"},"discovery":{"categories":{"all":[{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.7845,"source":"bisac_hint_model"},{"bisac_code":"FIC022090","confidence_band":"medium","label":"Private Eye Fiction","score":0.7759,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.774,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.7845,"source":"bisac_hint_model"},{"bisac_code":"FIC022090","confidence_band":"medium","label":"Private Eye Fiction","score":0.7759,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.774,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC019000","confidence_band":"high","label":"Literary Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC022000","confidence_band":"high","label":"Mystery","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC022080","confidence_band":"high","label":"International Crime Fiction","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"International Crime Fiction","score":0.7845,"slug":"international-crime-fiction"},{"label":"Private Eye Fiction","score":0.7759,"slug":"private-eye-fiction"},{"label":"British Mystery","score":0.774,"slug":"british-mystery"}],"reader_fit":["Good for readers who enjoy International Crime Fiction","Good for readers interested in suspense","Good for fans of Mystery"],"related_lists":[{"intro":"","slug":"shelf-fic022080-international-mystery-crime","title":"International Mystery & Crime Books","url":"https://bookfrontier.com/lists/shelf-fic022080-international-mystery-crime"},{"intro":"","slug":"shelf-fic022030-traditional-british","title":"Traditional British Books","url":"https://bookfrontier.com/lists/shelf-fic022030-traditional-british"},{"intro":"","slug":"shelf-fic022090-private-investigators","title":"Private Investigators Books","url":"https://bookfrontier.com/lists/shelf-fic022090-private-investigators"}],"series":null,"similar_books":[{"authors":["Edgar Wallace"],"book_id":"9781952438714","cover_image_url":"https://img.bookfrontier.com/9781952438714.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":16.0828,"title":"The Dark Eyes of London","url":"https://bookfrontier.com/books/9781952438714"},{"authors":["Colin Dexter","Samuel West","Macmillan Digital Audio","& 0 more"],"book_id":"9780804114899","cover_image_url":"https://img.bookfrontier.com/9780804114899.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":15.9821,"title":"Secret of Annexe 3","url":"https://bookfrontier.com/books/9780804114899"},{"authors":["Earl Derr Biggers"],"book_id":"9798880925810","cover_image_url":"https://img.bookfrontier.com/9798880925810.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":15.9716,"title":"The Black Camel","url":"https://bookfrontier.com/books/9798880925810"},{"authors":["A.E.W.
