Book excerpt: From London's fog to Arabia's sands, a Legend gallops into Myth. When a murdered aristocrat and a stolen obsidian statuette draw Sherlock Holmes and Dr Watson into a web of intrigue, they embark on a journey that will challenge their wit, courage, and very understanding of the world. The trail leads from the thundering hooves of the Epsom Derby to the ancient trade routes of Constantinople, and deep into the heart of the Arabian desert. As they uncover the secrets of the Obsidian Guild, Holmes and Watson find themselves entangled in a mystery that spans centuries, threatens empires, and reveals the timeless bond between man and horse. Joined by an extraordinary team - the enigmatic Dr Amal El-Sharif, the determined Princess Liyana Sultan, the skilled craftsman Adrien d'Arcy, and the horse-whispering Khalid Al-Fahmi - our intrepid duo must decipher cryptic scrolls, navigate treacherous alliances, and confront an enemy as old as civilisation itself.
