"How do you know?" And Dolly spoke in low, guttural tones, way down in her throat.
"Oh, you needn't growl like a little bear cub! I know you, because you're so careful of that left wing of yours. You thought nobody would notice it, did you? But I spied it, and I know you're Dot! You've got on a couple of coats or something to make you look fatter, but you're Dotty, all right."
Dolly shook with laughter, for she had pretended to shield her left arm with a gesture that was purposely copied from Dotty.
Just then the tall ghost appeared again at Dolly's side. He laid his hand on her shoulder and bent down a little to look in her eyes.
Dolly drew away from him and turned to Elmer Holmes.
"Who?" she said, in a hoarse whisper, pointing to the tall phantom.
"That's telling," said Elmer, laughing. "Ask him yourself who he is."
"Who?" grunted Dolly again, addressing herself to the tall one.
"Peter, Peter, Pumpkin-Eater!" and the tall ghost grunted out the words from one corner of his mouth and Dolly could not recognise the voice. As the ghost spoke he patted Dolly on the head.
Dolly disliked his manner, for none of the other boys were other than correctly formal and polite, so she turned away from him, making a gesture of dismissal with her hand.
