In 1973, the BBC made a documentary called The Eight Man That Never Was.

70 years ago, in a laboratory setting, Fardimood from that of the Department of Geodesy and Geophysics in Cambridge.

It looked at one of the most famous scientific discoveries ever made.

The archaeological findings that supposedly proved Britain was home to the missing link between apes and humans.

For 40 years, these fossils have been considered a scientific breakthrough.

The only problem, the whole thing, was a fraud.

People wanted to know who was behind it and how they pulled it off.

It was possible, for some personal persons unknown, to embark on an elaborate piece of forgery in the field of human evolution.

And because the scientific tests of today were then not available, it was possible for them to get away with it.

Who was the hoaxer? Why did they do it?

That's Miles Russell, a British archaeologist and university lecturer.

That becomes the major attention of the press.

And you see, throughout the 1970s and 80s, lots of different books, lots of different TV programs and documentaries made about the potential fraud.

Who would perpetuate such a hoax and why is one of the great mysteries of our times?

We will now go in search of history to scrutinize the hoax of the ages.

People were obsessed with figuring out who was behind the scam and there were plenty of suspects.

Some people suspected it was one of the many British scientists who built their careers by supporting the Pilt Down Man findings.

Others thought the fraud was so clever that only a truly brilliant mind could have pulled it off.

Perhaps the same mind who had invented Sherlock Holmes?

You've got Arthur Conan Doyle, the author living nearby.

We know that he's interested in fakes and forges.

So we're always different theories have been brought up.
