I’m going to tell you the story of the man who solved a crime.

Not, like, a cop who put together the clues and got his man, but a person who took a crime as old as civilization and fixed the problem where it got you in trouble.

The man: Artur Virgílio Alves Reis.

The place: 1920s Portugal.

The crime: Counterfeiting.

The problem he fixed: That the money is counterfeit.

(This is going to be a long 🧵 . Just trust me.)
