Marjorie held up the key by the string and swung it in front of her brother. “I don’t know why I couldn’t find it before.”

Nick had a strange look on his face. He seemed to be looking right through Marjorie. Suddenly he started to laugh.

“What’s wrong with you, Nick?” Marjorie asked.

“Marge, the spell worked!” Nick said. “But not the way we wanted it to. The key vanished. And so have you!”

Marjorie looked at the key swinging from her hand. “I don’t know what you’re talking about.”

“Don’t argue, Marge.” Nick held out his hand. “Just give me the key for a minute.”

Marjorie dropped the key into Nick’s hand. When she let go of the string, she couldn’t see it anymore. And she couldn’t see Nick, either. She blinked. Then she understood. “Now do you see the key, Nick?”

“Yes,” Nick said. “And I can see you too.”

“But now I can’t see you, or the key,” Marjorie told him.

“You can have the key back, Marge.” Nick put it in her hand. At once she could see him.

Marjorie hung the key around her neck. She picked up the Domino Sugar bag with one hand and held it just below the edge of the table. With her other hand Marjorie swept the desert sand into the bag. “Can you see what I’m doing, Nick?”

“I see the sand moving itself into the sugar bag,” Nick said. “It looks weird.”

“Then it’s just the key, not everything I touch, that disappears.” Marjorie took the bag of sand and the bottle of tigers’ teeth back to the shelf where they had found them.

“Your clothes are invisible,” Nick said. “What happens if you put something into your pocket?”

The wooden spoon was on the table. Marjorie went over and picked it up. Nick watched the spoon rise from the table.

“This is too big to go in my pocket,” Marjorie said.

“It’s gone, Marge. What did you do with it?” Nick asked.

“I tucked it under my shirt.” Marjorie started to turn the pages of the big book.

“Cut it out, Marge. You’re giving me the creeps,” Nick said. “It looks as if those pages are flipping over all by themselves.”

Marjorie took the key from around her neck and laid it on the table. “Is that better?”

“Much,” Nick said. “I can see you now. What are you looking for in the book?”

“There’s something I always wanted to do,” Marjorie said, “ever since I saw Peter Pan on television.”
