“That is a point，” said the Professor， “which certainly deserves consideration； very careful consideration. For instance.if you will excuse me for asking the question. does your experience lead you to regard your brother or your sister as the more reliable？ I mean， which is the more truthful？”
“That’s just the funny thing about it， sir，” said Peter. “Up till now， I‘d have said Lucy every time.”
“And what do you think， my dear？” said the Professor， turning to Susan.
“Well，” said Susan， “in general， I’d say the same as Peter， but this couldn‘t be true.all this about the wood and the Faun.”
“That is more than I know，” said the Professor， “and a charge of lying against someone whom you have always found truthful is a very serious thing； a very serious thing indeed.”
“We were afraid it mightn’t even be lying，” said Susan； “we thought there might be something wrong with Lucy.”
“Madness， you mean？” said the Professor quite coolly. “Oh， you can make your minds easy about that. One has only to look at her and talk to her to see that she is not mad.”
“But then，” said Susan， and stopped. She had never dreamed that a grown.up would talk like the Professor and didn‘t know what to think.
