Sherlock Holmes and The Scottish Question

What if the most celebrated consulting detective in the world, at the height of his powers in 1897, was on the trail of the ancient lost Crown of Scotland? The crown, its history lost in the mists of time, was torn from the head of defeated Scottish King John Balliol by Edward the First of England. It was sent to Canterbury Cathedral for safekeeping, and never seen again. Or was it? What if the most potent symbol of Scottish sovereignty was stolen from its hiding place in the most secure stronghold in England? If members of the British Royal Family were abducted, threats made against the Queen, and a campaign of terror planned by Scottish separatists aided by a Great Power? Holmes and Watson track a conspiracy against the Union by some of the highest in the land, threatening the dissolution of Great Britain and a bloody European war of cataclysmic proportions. A Sherlock Holmes case recorded by Doctor John Watson with perhaps a touch of wry humour.
