The choice of a silhouette suggests both clarity and mystery, reflecting Holmes' clarity of thought and the mysteries he solves. The scarlet red, used both as a color overlay and for the title, ties into the book's namesake and the themes of vengeance and emotion. Typography choices, with a mix of serif and sans-serif, balance the historical aspect of the story with a modern aesthetic, making it accessible and eye-catching for contemporary readers. The use of high-quality matte paper adds a tactile element that complements the visual elegance of the design, inviting readers to physically engage with the book in a way that hints at the depth of the narrative within.
