(From the publisher):
'Casper and Johnny pelted up to Gwinny's room regardless of noise. Johnny thought she was on fire, Casper thought she was being eaten away by acids. They burst into the room and stood staring. Gwinny did not seem to be there. Her lamp was lit, her bed empty, her window shut, and her dollshouse and all her other things arranged around as usual, but they could not see Gwinny.
'"She's gone," said Caspar, helplessly.
'"No, I haven't," said Gwinny, her voice quiverring rather. "I'm up here." Gwinny appeared to be hanging from the ceiling. She looked a bit like a puppet. "And I can't come down," she added.'
She couldn't either. At least not until the vol. pulv. splashed on her from Johnny's chemistry set had worn off. The chemistry set had been a surprising present from the Ogre, her stepfather. They hated him, and they hated his two sons, Malcolm and Douglas, just as much. When they weren't wishing themselves dead, they wished the Ogre and Malcolm and Douglas were.
At any rate, the chemistry set looked like being a distraction. Especially when it proved to contain such curious chemicals. They saw what vol. pulv. did to Gwinny, and of course, tried it out on themselves.
