"Let's get out of this," whispered Jimmy as they got to the end of the hall.
But the voice of the Princess said: "Come out this way; it's quicker.
I think you're perfectly hateful. I'm sorry I ever played with you.
Mother always told me not to play with strange children."
A door abruptly opened, though no hand was seen to touch it.
"Come through, can't you!" said the voice of the Princess.
It was a little ante-room, with long, narrow mirrors between its long, narrow windows.
"Good-bye, said Gerald. "Thanks for giving us such a jolly time.
Let's part friends, he added, holding out his hand.
An unseen hand was slowly put in his, which closed on it, vice-like.
"Now," he said, "you've jolly well got to look in the glass and own that we're not liars."
He led the invisible Princess to. one of the mirrors, and held her in front of it by the shoulders.
"Now," he said, "you just look for yourself." There was a silence, and then a cry of despair rang through the room.
"Oh oh oh! I am invisible. Whatever shall I do?"
