Digory quite liked the cave （she wouldn’t let him see the story） but he was more interested in exploring.
“Look here，” he said. “How long does this tunnel go on for？ I mean， does it stop where your house ends？”
“No，” said Polly. “The walls don‘t go out to the roof. It goes on. I don’t know how far.”
“Then we could get the length of the whole row of houses.” “So we could，” said Polly. “And oh， I say！”
“What？”
“We could get into the other houses.”
“Yes， and get taken up for burglars！ No thanks.”
“Don‘t be so jolly clever. I was thinking of the house beyond yours.”
“What about it？”
“Why， it’s the empty one. Daddy says it‘s always been empty since we came here.”
“I suppose we ought to have a look at it then，” said Digory. He was a good deal more excited than you’d have thought from the way he spoke. For of course he was thinking， just as you would have been， of all the reasons why the house might have been empty so long. So was Polly. Neither of them said the word “haunted” . And both felt that once the thing had been suggested， it would be feeble not to do it.
“Shall we go and try it now？” said Digory. “Alright，” said Polly.
“Don‘t if you’d rather not，” said Digory. “I‘m game if you are，” said she.
