should write to Hobbies magazine and find out if your doohickey is worth something. In the meantime, however, if I were you, I'd keep the thing hidden. If your Gramma sees it, she'll ask where it came from, and then where would you be? Just take it back and put it in your closet. First, though, you'd better make sure the coast is clear. Come on. I'll go down with you and check."
Johnny took the book in his arms and followed the professor downstairs. At the front door they stopped, and the professor peered cautiously out.
"Good!" he said, nodding. "They're not back yet. You'd better get while the getting is good. Bon voyage! And don't forget about our chocolate cake date tonight!"
"I won't," said Johnny, grinning. "G'bye!"
While the professor held the door for him Johnny raced across the street. Into the house he went, and up the stairs to his room. Once again he put the old black book in the bottom of his closet. Again he piled stuff on top of it. Then he closed the closet door and went across the hall to wash his hands, which were dirty from handling the book.
That evening at dinner, just as Gramma was about to serve dessert, Johnny announced that he had been invited over to the professor's house for cake and a chess game. He announced this shyly and hesitantly, because he didn't know what Gramma's reaction would be. Grampa was a pretty easygoing sort—he usually let Johnny do what he wanted to do. But Gramma was more strict, and she didn't like the professor much. Furthermore she was proud of her desserts—Johnny didn't want to hurt her feelings or make her angry.
But all Gramma said was "Humph! I guess it's all right." And she added, in a disparaging tone, "I didn't know he baked cakes." Gramma had lived across the street from Professor Childermass for twenty years, but there were a lot of things she didn't know about him.
Johnny excused himself and went across the street. He had a great time that evening. The professor was a crafty and merciless chess player. He was every bit as good as Johnny was, and maybe even a bit better. As for the cake... well, Johnny had theories about chocolate cake. He felt that the cake part of the cake was just an interruption between the layers of frosting. As it turned out, the professor's opinions about cake were similar to Johnny's. The cakes he served had three or four thin layers, and the rest was a huge amount of good, dark, thick fudgy frosting. And he served second helpings too.
Around ten o'clock that night Johnny said good-bye to the professor and started across the street toward his house. He paused on the curb for a minute or two to look around. It was a beautiful cold winter night. Icicles hung from all the houses, and they glimmered gray in the moonlight. Snowdrifts lay everywhere. In the street were ridges of ice, knotted and iron-hard. Johnny blew out his cloudy breath and felt contented. He had made a new friend, he was stuffed with chocolate cake, and he had won one of the three chess games they had played. Once more he looked around, and then he stepped forward into the street. As he stepped he happened to glance to his left, and he stopped dead.
There was somebody standing across the street, watching him.
Johnny stared. Who was it? He couldn't tell. All he could see was a short, stocky figure standing in front of Mrs. Kovacs's house.
"Hi!" called Johnny, waving.
No answer. The figure did not move.
Oh, well, thought Johnny, it's probably Mr. Swart-out. Mr. Swartout was a creepy little man who lived at the end of the street. He never said anything to anybody —wouldn't give you the time if you asked him for it.
Shrugging, Johnny walked straight on across the street and into his house. Later, upstairs, when he was in his pajamas and getting ready to climb into bed, Johnny looked out the window. His bedroom was at the front of the house. From it you could get a good view of the whole length of Fillmore Street. He looked toward the place where the figure had
