If somebody says the right words, promises the right things, anybody can become a victim.

It's just unheard of. Crimes like this don't exist.

When was the last time you received a letter in the mail? Think about it. A real, handwritten letter from someone who knows you, really cares about you. Since the early 2000s, millions of hand written letters were landing at people's doors all across America, each one offering the receiver a tailored reading into their future.

I got this letter in the mailbox addressed to myself personally from Maria Duval.

For just a small fee, you could have the life you always dreamed of. All you had to do was believe.

She truly believed that somehow this was going to save her mind from going further into the depths of demand shop.

They gave you the return envelope that was pre-printed, ready to go. Put your check in it and mail it back to them.

All you have to do is grasp the hand of friendship We are holding out to you, your devoted friend, Maria Duval.

Maria Duval. But who really was the French psychic Maria Duval? And did she know her letters were part of a multimillion dollar scam defrauding people from all across the world?

It was an out and out scam.

They'd been without water for two months, or they couldn't afford to get their groceries. All they wanted in return was whatever it was that Maria Duval was promising them.

But when you add up the volume, we never in our wildest dreams thought that these schemes were at this scale.

This has got to be one of the worst crimes in all of history.

I'm investigative journalist, Rachel Brown, and I'm going to tell you the story of a scam unlike anything I've ever seen.

1.4 million unique Americans were victimized. Now, there's 330 million people in the United States, so that is one out of every 300 men, women, and children walking down the street.

The whole operation raked in almost $200 million and found its way from Canada, the United States, all across Europe, and even to Australia. It's a story of a shapeshifting mastermind who evaded capture for more than 20 years, and the victims, vigilantes, and law enforcement around the world bringing them to justice.

They're the archetype of larger-than-life characters that have no conscience in what they do.
