{"product_id":"sherlock-holmes-in-the-adventure-rr-thwackhurst-9798249192983","title":"Sherlock Holmes in The Adventure of the Undersea Plans","description":"When Admiral Sir Reginald Carlton arrives at 221B Baker Street on a grey February afternoon, he brings a problem that touches both personal grief and national security. His nephew, Lieutenant Peter Carlton, has been found dead in his Portsmouth lodgings, officially from heart failure, but the Admiral's instincts tell him something is profoundly wrong. \u003cp\u003e\u003c\/p\u003eThe young naval officer had recently become engaged to Miss Elise Vogel, a talented German pianist who moves gracefully through London's finest drawing rooms. He also had access to Britain's most closely guarded secret: the specifications for revolutionary submarine propulsion designs. \u003cp\u003e\u003c\/p\u003eHolmes and Watson plunge into a world where Schumann recitals conceal treachery, where musical notation encodes stolen specifications, and where a beautiful woman's composure masks something far colder than sentiment. From the gaslit disorder of Baker Street to the naval yards of Portsmouth, from a Whitechapel photographer's shop to a midnight encounter in Dover, they trace a plot of devastating elegance, one executed by a professional who has learned to partition sentiment from necessity with chilling precision. \u003cp\u003e\u003c\/p\u003eWhat Holmes uncovers is a truth more troubling than simple villainy: that evil in the modern age wears a civilized face and believes itself to be acting rightly. A tale of espionage and moral ambiguity in which order must be wrested from chaos, truth pursued at any cost, and the real enemy may not be the spy but the system that created her.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Rr Thwackhurst\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798249192983\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/20\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 54\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.14lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.00h x 5.00w x 0.13d","brand":"Rr Thwackhurst","offers":[{"title":"Paperback","offer_id":48454432194815,"sku":"9798249192983","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f663b3c1-70c2-4c89-9a00-bd0198236ef8.jpg?v=1777306206","url":"https:\/\/www.whiterainbookhouse.com\/products\/sherlock-holmes-in-the-adventure-rr-thwackhurst-9798249192983","provider":"WR Book House","version":"1.0","type":"link"}
