“Now，” said Peter in a quite different voice， “it’s about time we four started using our brains.”
“What about？” asked Edmund.
“Have none of you guessed where we are？” said Peter. “Go on， go on，” said Lucy. “I‘ve felt for hours that therewas some wonderful mystery hanging over this place.” “Fire ahead， Peter，” said Edmund. “We’re all listening.” “We are in the ruins of Cair Paravel itself，” said Peter.
“But， I say，” replied Edmund. “I mean， how do you make that out？ This place has been ruined for ages. Look at all those big trees growing right up to the gates. Look at the very stones. Anyone can see that nobody has lived here for hundreds of years.”
“I know，” said Peter. “That is the difficulty. But let‘s leave that out for the moment. I want to take the points one by one. First point： this hall is exactly the same shape and size as the hall at Cair Paravel. Just picture a roof on this， and a coloured pavement instead of grass， and tapestries on the walls， and you get our royal banqueting hall.”
No one said anything.
“Second point，” continued Peter. “The castle well is exactly where our well was， a little to the south of the great hall； and it is exactly the same size and shape.”
Again there was no reply.
