"Let's go!" Henry said to Maggie.
Without waiting for her, he rushed over to Kyle.
Coach Phillips was hurrying toward him too.
Everyone else had stopped whatever they were doing and turned to stare.
"What happened?" Henry asked when he reached Kyle.
Kyle's large blue gym bag was sitting on a chair near the pool.
Its zipper was halfway open.
When Henry looked down into the opening, he saw a puddle of green.
The green paint was all over Kyle's sneakers, T-shirt, and other belongings.
"All my stuff is ruined!" Kyle complained.
The coach reached them.
"This is outrageous!" he exclaimed as he looked into Kyle's bag.
Then he spun around. "Someone had better confess right now!
Otherwise I'm going to cancel these tryouts!"
"Oh no!" Daisy exclaimed.
Kyle glared at Cole, who was standing a short distance away.
"It was him!" he said, pointing.
"Everyone knows he's the one who dumped those frogs in the pool.
He must have done this too!
He's afraid I'll beat him for that spot on the team!"
"Cole didn't do anything!" Maggie said.
"You probably put that paint there yourself, Kyle!
If there's any paint in your bag, that is."
Henry realized that nobody could see the paint except for him, Kyle, and the coach.
"There's really paint in here, Maggie," he said.
"The only question is how it got there."
"Yes," Coach Phillips agreed.
"And I want an answer to that question right now!
I also want to know who brought those frogs to the pool."
Just then Tommy came out of the pool building.
When he saw everyone staring at Kyle, he looked confused.
"What's going on?" he asked, hurrying over.
"That's a very good question," Coach Phillips said.
"We're trying to figure out who's responsible for all of today's pranks."
"I know the answer," Maggie declared. She pointed at Tommy. "He did it!"
"What?" Tommy exclaimed.
Henry winced. He thought Tommy was probably the culprit too.
But they still had no way to prove it.
Why did Maggie have to have such a big mouth?
John looked angry.
"How dare you accuse my brother of something like that!" he yelled at Maggie.
"Tommy didn't have anything to do with this!"
Maggie didn't back down, even though John was a lot older.
"That's not what we think!" Maggie yelled back. "Right, Henry?"
"I don't understand," Tommy said, looking confused.
"What happened? Are the frogs in the pool again?"
"No," Tiny told him. "Someone poured paint in Kyle's bag."
"You want to make everyone think that Cole did all these pranks," Maggie went on.
"How did you do it?"
"That's ridiculous." John scowled.
"It was Cole. Everyone knows he has pet frogs."
"Right!" Lauren jumped in.
"You probably poured that green paint in Kyle's bag too," John went on.
He looked around. "Or maybe it was Daisy. Everyone knows she likes to paint!"
"What?" Daisy cried. "I didn't do anything!"
"And like I keep telling everyone, I didn't put those frogs in the pool!" Cole added.
"I would never do something like that.
Pool water isn't good for frogs!"
Everyone started yelling at once.
Maggie was yelling at Coach Phillips about evidence.
John was yelling that Tommy was innocent.
Kyle was yelling about his bag being ruined.
Cole and Daisy were yelling that they hadn't done anything wrong.
Everyone else was yelling out questions.
But Henry wasn't yelling. He was thinking.
Something someone had just said didn't make sense.
That was a clue. A big one!
Suddenly he realized who was behind all the trouble.
"Hold on," he said. "I know who did this."
Nobody heard him. Everyone else was still yelling.
So Henry stuck his fingers in his mouth and let out a loud whistle.
Everyone fell silent for a second. They all turned to look at Henry.
"I know who did this," he said again.
"You do?" Maggie asked.
"Of course he does," Kyle said. "Henry is friends with Cole.
He probably even helped Cole.
Why else would he hang around the pool all day?"
"Yeah." John rolled his eyes. "Why are we even listening to him?
He doesn't know anything."
"He might," Daisy said. "Haven't you heard about The Lemonade Detectives?
Henry and his friends helped my neighbor find his lost keys last week."
"Really?" Tiny asked. "That's cool. Can you guys find my lost cell phone?"
"Quiet!" Coach Phillips shouted.
"Henry, do you really know something about all this?"
Henry nodded. "Cole didn't have anything to do with the pranks," he said.
"Neither did Daisy or Kyle or Tommy."
"Then who did it?" Maggie asked.
Henry looked over at Tommy's brother. "It was John."
