This should be a sequel to The fraudster from London
The following story is a sequel to another story, but I made an error, the correct one is there:
Having finished his supper, Vincent Blavet was inspecting this little piece of paper, this insignificant cluster of fibers that people wanted to pass for checks, they wanted to get exorbitant sum of money with this little piece of paper. They really thought that with a little piece of paper, they would get a direct ticket to the riches world, casinos, restaurant, billions peaking out of their pockets. They didn’t know how to do it, he knew how. His checks were real. Real checks making him win zillions of dollars. Hi didn’t make checks, he tampered with them. There lay the secret of his success. He, Vincent Blavet, a simple clerk, controlled a gigantic economic empire and unlike a popular Roman conqueror, there was no little village resisting him.
