"That was a neat program on UFO's," said Nina to her cousin Max as they walked down the street. "I think what really amazed me was that UFO's were reported as early as 1800."
"That's pretty hard to believe," said Max. "Anyway, do you really believe there are such things?" Nina started to answer when they heard a loud scream coming from Coach Thornton's house.
"Come on," shouted Max. They ran into the yard where the coach was staring at ten rose bushes that had been pulled from the ground.
"Look at that!" he demanded. "Just look at that."
"That's terrible," cried Nina. "Who could have done it?"
Coach Thornton looked disgusted. "I had to bench three of my best football players for cutting class. They were pretty mad at me."
"First thing, we'd better get these roses back in the ground," said Max. "Then we'll figure out who did it."
Nina and Max helped Coach Thornton replant the roses. Then he invited them in for milk and cookies.
"Now," said Nina. "Am I right? You benched Sam Cartland, Mike Brooks, and Alex Avery."
"And you lost the game," added Max.
The coach rubbed his eyes. "I know, but rules are rules."
"I'll bet one of them did it to get even," said Nina. "How about we nose around a little?"
"Let's see," said Max after they left. "Coach said the roses were all right when he looked out at nine. But shortly after ten, he found them pulled up."
"So, we check to see who doesn't have an alibi between nine and ten. Look!" Nina pointed. "There's Alex Avery over at the Dairy Bar."
Alex looked up as they came in. "Hi kids," he drawled.
"Hello, yourself," said Max. "We missed seeing you in the football game."
"That was a bummer all right. But I guess the coach didn't have any choice."
"Where you been all morning?" asked Nina.
"I've been right here since nine." He turned to the girl behind the counter. "Isn't that right, Amy?"
"Uh huh. You helped me carry in that heavy box."-
