Arthur Conan Doyle, a doctor and struggling writer, invents the perfect detective, Sherlock Holmes, whose popularity eclipses Doyle’s literary ambitions. Fiction and reality collide as Holmes materializes to debate his creator, culminating in the fateful “final problem.” Themes include authorship, identity, the cost of success, and the uneasy bond between artist and creation. Tone: intimate, fast-paced, reflective; musical style blends lyrical ballads with rhythmic, dialogue-driven numbers.
