The entrance shaft sloped downward at a terrifying angle. I descended in a crouch, unsettled by a combination of vertigo and claustrophobia. Ahead, our four boys were chattering nervously as they half-walked, half-slid into the heart of the pyramid. They knew enough about ancient Egypt, Indiana Jones and Tomb Raider to know that this was a Really Big Adventure, something that few six and nine year-olds would get the chance to do.
