The word "semaphore" in literature often appears as a symbol of discreet communication and technological innovation. For example, in Arthur Conan Doyle's "His Last Bow: An Epilogue of Sherlock Holmes" [1], semaphore is mentioned alongside other signaling methods such as lamp code and even Marconi’s wireless transmissions. This usage not only underscores its role as a practical tool for sending coded messages but also illustrates how authors have long been intrigued by the mechanics of communication—integrating technical details into narrative settings to evoke an atmosphere of mystery and intrigue.
