A debut novel worth falling for. ” —Matthew Pearl, author of The Dante Chamber Physician Arthur Conan Doyle takes a break from his practice to assist London police in tracking down Jack the Ripper in this debut novel and series starter. September 1888. A twenty-nine-year-old Arthur Conan Doyle practices medicine by day and writes at night. His first Sherlock Holmes story, A Study in Scarlet, although gaining critical and popular success, has only netted him twenty-five pounds. Embittered by the experience, he vows never to write another \"crime story.\" Then a messenger arrives with a mysterious summons from former Prime Minister William Gladstone, asking him to come to London immediately. Once there, he is offered one month's employment to assist the Metropolitan Police as a \"consultant\" in their hunt for the serial killer soon to be known as Jack the Ripper. Doyle agrees on the stipulation his old professor of surgery, Professor Joseph Bell--Doyle's inspiration for Sherlock Holmes--agrees to work with him. The two are joined by Miss Margaret Harkness, an author residing in the East End who knows how to use a Derringer and serves as their guide and companion. Pursuing leads through the dank alleys and courtyards of Whitechapel, they come upon the body of a savagely murdered fifth victim. Soon it becomes clear that the hunters have become the hunted when a knife-wielding figure approaches.","forthcoming":false,"isbn13":"9781633884861","publication_date":"20181002","publisher":"Seventh Street Books","slug":"a-knife-in-the-fog","subtitle":"Kindle Edition","title":"A Knife in the Fog"},"discovery":{"categories":{"all":[{"bisac_code":"FIC022060","confidence_band":"medium","label":"Historical Mystery","score":0.8034,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.7951,"source":"bisac_hint_model"},{"bisac_code":"FIC031020","confidence_band":"medium","label":"Historical Thrillers","score":0.7811,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC022060","confidence_band":"medium","label":"Historical Mystery","score":0.8034,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.7951,"source":"bisac_hint_model"},{"bisac_code":"FIC031020","confidence_band":"medium","label":"Historical Thrillers","score":0.7811,"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":"FIC031020","confidence_band":"high","label":"Historical Thrillers","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Historical Mystery","score":0.8034,"slug":"historical-mystery"},{"label":"British Mystery","score":0.7951,"slug":"british-mystery"},{"label":"Historical Thrillers","score":0.7811,"slug":"historical-thrillers"}],"reader_fit":["Good for readers who enjoy Historical Mystery","Good for readers interested in mystery","Good for fans of Mystery"],"related_lists":[{"intro":"","slug":"shelf-fic022060-mystery-detective-historical","title":"Mystery & Detective Historical Books","url":"https://bookfrontier.com/lists/shelf-fic022060-mystery-detective-historical"}],"series":null,"similar_books":[{"authors":["Bradley Harper"],"book_id":"9781645060079","cover_image_url":"https://img.bookfrontier.com/9781645060079.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":26.7199,"title":"Queen's Gambit","url":"https://bookfrontier.com/books/9781645060079"},{"authors":["Timothy Miller"],"book_id":"9781645060819","cover_image_url":"https://img.bookfrontier.com/9781645060819.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":19.6213,"title":"The Strange Case of the Pharaoh's Heart","url":"https://bookfrontier.com/books/9781645060819"},{"authors":["Kate Reading","Sherry Thomas","Penguin Audio","& 0 more"],"book_id":"9780425281406","cover_image_url":"https://img.bookfrontier.com/9780425281406.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":19.3907,"title":"A Study in Scarlet Women","url":"https://bookfrontier.com/books/9780425281406"},{"authors":["Gordon McAlpine"],"book_id":"9781633882072","cover_image_url":"https://img.bookfrontier.com/9781633882072.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":16.5849,"title":"Holmes Entangled","url":"https://bookfrontier.com/books/9781633882072"},{"authors":["Edgar Wallace"],"book_id":"9781952438714","cover_image_url":"https://img.bookfrontier.com/9781952438714.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":16.4912,"title":"The Dark Eyes of London","url":"https://bookfrontier.com/books/9781952438714"},{"authors":["A.E.W.
