Roxy had to get to the Metro City Mint.
The Ghost Bandit was there, and she needed to catch him.
"Hey, everybody," said Roxy to her friends.
"I think I should go home.
I, um, don't feel well."
"Hmm," said Terrell after Roxy left.
"I guess that's why she seemed upset."
Roxy soon arrived at the Metro City Mint.
Police surrounded the entire building.
Detective Smith waved to her.
Roxy flew down.
"Is this a surprise party for the Ghost Bandit?" asked Roxy.
Detective Smith frowned.
"No, it's not a surprise party."
"I'm just kidding," said Roxy.
"So where is he?"
"The Ghost Bandit is still in the mint," said the detective.
"But we don't know where, since he's invisible."
Roxy nodded. "He's not an easy villain to catch.
I almost caught him earlier today.
But he got away.
Everyone thinks I was trying to destroy Metro City."
"I know," said Detective Smith.
"We need to catch him soon."
"Yes, very soon," said Roxy.
"People are starting to think I'm a villain!"
"I wish we knew how he makes himself invisible," said Detective Smith.
Roxy thought for a moment.
"He must have a special suit.
I don't think he's a real ghost."
"You don't?" asked Detective Smith.
He looked doubtful.
"No," said Roxy.
"A real ghost would be able to move through walls.
But this villain uses doors."
"You're right," said Detective Smith.
Roxy stepped toward the building.
"I'll use my super hearing," she said.
"Maybe I can hear where the Ghost Bandit is."
Roxy closed her eyes and listened carefully.
She heard a fan humming in an office.
She heard a tiny bug flying down a hallway.
And then she heard footsteps.
Roxy's eyes popped open.
"I heard him! He's walking!"
Roxy shot into the mint and followed the sound of the footsteps.
She arrived in a huge room filled with tall stacks of money.
The stacks were in long, neat rows.
It looked like some of the money was missing.
Roxy walked between the rows of money.
"I wonder where the Ghost Bandit is," she thought.
Roxy listened carefully again.
She heard breathing.
"Hey, Ghost Bandit!" Roxy cried.
"I know you're in here!"
"Boo!" A voice called out and then laughed.
Roxy leaped onto a stack of money.
She looked around but didn't see anyone.
"I'm wearing an invisible suit," said the voice.
"You'll never find me!"
