Monty Hall is not the host. This is not "Let's Make a Deal." But everyone wants to know: What's behind door number one? And the only person who seems to have a clue is a clairvoyant. Is she right? We may never know, as authorities deny a door even exists. Where? At the Great Pyramid at Giza.

A few years ago a small robotic camera piloted by a German engineer found that one of the "air shafts" leading to the Queen's Chamber was blocked by something unexpected: a stone "door" with a small copper handle attached -- one of a pair, actually, as the other was lying on the floor of the shaft. But the Egyptological establishment refused to believe that the stone at the end of the shaft was anything more than simple stone block and banned anyone from further exploring the mystery.

But that didn't stop Ann Walker. A noted clairvoyant, Walker has already seen and described what lies behind the mystery portcullis. There are at least two chambers beyond the door, according to Walker, and when these are opened they will reveal a treasure greater than King Tut's. A series of images drawn by Walker depicting what she saw now are available on the Internet.

"Walker is not an Egyptologist," says Adrian Gilbert, co-author (with Robert Bauval) of The Orion Mystery, a book which claims to unlock the secrets of the pyramids, "and would have no more access to the pyramid than any other member of the general public. She is, however, an extraordinary clairvoyant. But as to the accuracy of her remote viewing, none of us will know until the robot finally reveals all."

No one knows yet whether that lucky robot will belong to a Japanese, Swiss, or Canadian team, all of whom have requested permission from the Egyptian authorities to further explore the shaft. "Clearly the TV rights for a live show where a robot climbed the shaft and peeped behind the slab for the first time would be worth millions," notes Gilbert.

Now if only someone could get Monty Hall to host the show.
