Sherlock Holmes has been missing for three days. In principle, Dr. Watson doesn´t think much of it because the detective has done this before. However, from the end of the second day, Watson begins to worry and faints upon receiving news of Mycroft Holmes, who, supported by agents from the secret service office, follows the trail of Sherlock Holmes and Irene Adler through some Scottish islands, while he is sure that they are going to get married in secret. Moreover, Mycroft Holmes is extremely concerned: from the Queen’s stable, three horses that will represent the nation in an international classic have been abducted, and also the niece of the Secretary for European Affairs, Sir Trelawney Hope (whose political power surpasses the influence of the British prime ministers of the last decade), has been kidnapped. In addition to this, a dark secret persists with the missing niece, and the geopolitical consequences of both cases could be fatal for the Conservative Party and the English government, who would lose respect and credibility in the European community and the British colonies. Mycroft Holmes and Watson are upset by the irresponsible and insane attitudes of Sherlock Holmes, who claims to be on vacation. Although the great detective is aware of the delicate situation, and working remotely, he sends telegrams that allow his brother and Watson to get to the bottom of the truth and solve these complicated cases. And following the trail of a telegram from Sherlock Holmes and other deductions from inspector Patterson and Watson, who remembers other words from the missing detective, a Scotland Yard and secret service team, accompanied by Watson, and led by Mycroft and Lestrade, go to the Canary Islands, precisely to the third, known as La Gomera, with the purpose of finding Sherlock Holmes, capturing Irene Adler, preventing that wedding and recovering jewels stolen by that woman, including the Koh-i-Noor diamond.
