Firstly, I have to thank you for publishing this story, because I didn't know it. I did a brief research, and discovered that he was a big swindler spreading his cunning fantasies. He assumed the title of colonel, started wearing a badge from a Portuguese knight order, among other things. The convinced way in which he communicated deceived a large part of London society. I don't know if there is a film or series about his life? If you don't have it, you're wasting time!
