And finally, the man we spoke to who is perhaps most adamantly against the idea of conspiracy being related to Mary's death, that would be Ron Rosenbaum.

So there you have it. For the most part, all these writers, these individuals surrounding this complex story, they have the same set of facts. Yet their conclusions can be very different. And we haven't even acknowledged the simplest explanation of all. What if Ray did kill Mary?

The pieces of that puzzle aren't all in place either, but that theory requires fewer mental gymnastics than a CIA plot. After all, a witness placed him at the crime scene and he was caught shortly after the murder took place. But in the end, we just don't know. So what does all this mind-bending say about us? What does it say about the way we take in information and process it?

About the way we understand Mary's murder? Why are we all on such different pages? Joe Pierre has a pretty good answer for that.

It's something that has been studied in psychology research, he says. And the results are pretty fascinating.

For each one of us, it seems, the story of Mary's murder, if there's a conspiracy behind it or not, might be the perfect test case for the white Christmas effect. But like the movie where the songs performed, all the snow that made Christmas in Vermont white, it was produced on a California soundstage. It merely gave the illusion that the whole thing took place in Vermont.

But, my friends, it did not. And in the case of Mary's murder, the CIA's involvement is no more believable than all that fake snow, at least for a slew of reporters who know the story best. As questions surrounding Mary Meyer's death remain unanswered through the decades, the legacy of each woman would start to be written. Dovey Roundtree would go on to write a book about her amazing life.
