The summary is:
This is a transcript of a video that tells the story of a mysterious murder that occurred in 1908. Mariángel Crist, an elderly woman, was killed in her home by an unknown assailant who only stole a brooch with diamonds. The police arrested Oscar Slater, a gambler with debts, who was trying to sell a similar brooch, but he was not the real culprit. The case attracted the attention of Arthur Conan Doyle, the creator of Sherlock Holmes, who wrote a book exposing the flaws and inconsistencies of the investigation. He believed that the murderer had duplicated the keys to enter the house and that he was someone close to the victim who knew about her jewels and documents. However, he could not explain why he chose such a risky moment to act and why he left other valuables behind. The video suggests that it could have been a nephew of the victim who acted out of panic and greed, but the truth was never revealed.
