Even then she could not believe that he would harm her, and stretched out a tentative hand.

This time she made out the flash of his teeth as he snarled.

He was no longer the Bart she had played with around the cabin, but a strange wild thing, and with a scream she darted past him toward the door.

Never had those chubby legs flown so fast, but even as the light from the mouth of the cave glimmered around her, she heard a crunching on the gravel from behind, and then a hand, it seemed, caught her cloak and jerked her to a stop.
She fell sprawling, head over heels, and when she looked up, there sat Bart upon his haunches above her, growling terribly, and gripping the end of the cloak.

No doubt about it now.
