In 1971, a group of audacious criminals executed one of the most remarkable bank heists in history by tunneling into Lloyds Bank’s vault on Baker Street. With an elaborate plan inspired by a Sherlock Holmes story, they managed to access hundreds of safety deposit boxes while evading the police, who failed to check the premises. A combination of engineering skill, luck, and a lack of response from law enforcement led to a substantial amount of money and valuables being stolen, and many questions remain unanswered, including the true scale of the theft and the possibility of government intervention in the aftermath.
