"Where are you?" Roxy cried.
The Ghost Bandit was somewhere in the room.
But Roxy didn't know where.
Suddenly she heard someone running.
She spun around and saw a door quickly open and close.
"There he is!" Roxy leaped from the stack of money.
She burst through the door and into a long hallway.
The villain's footsteps went around a corner. Roxy followed.
As she turned the corner, she saw another door open.
Whiz-hoo! Roxy fired her eye laser beams.
Boom! The door exploded.
"Ha-ha! You can't see me!"
The Ghost Bandit laughed and kept running.
Roxy stood still and listened.
"I can hear his footsteps," she thought.
"He's running down another hallway."
Roxy followed, listening as she went.
The footsteps led into another big room.
This room had a huge machine along one wall.
The machine had big rollers and a conveyor belt.
Money covered the belt.
Buckets of ink sat nearby.
"This must be where workers print the money," thought Roxy.
Crash! A garbage can suddenly hit the wall near Roxy.
"Aargh!" cried the Ghost Bandit. "I missed!"
Roxy watched as another garbage can seemed to float into the air.
Then it shot toward her!
Roxy ducked just before the garbage can hit her.
It smashed against the big machine.
Roxy flew as fast as she could and tried to grab the bandit.
"Oh, you'll never catch me!" said the bandit.
Then he was quiet.
Using her super hearing, Roxy heard the villain's heartbeat nearby.
She flew toward the sound and tried to grab the Ghost Bandit again.
But again she missed.
The Ghost Bandit laughed.
Each time Roxy heard him, she flew to the sound.
But every time, the Ghost Bandit moved away.
"Grr!" Roxy stamped the floor.
The walls shook.
"I'm never going to stop this dumb villain if he's invisible!
I'm getting really tired of—oof!"
A box hit Roxy, knocking her over.
She bumped into one of the buckets of ink.
Some ink spilled on her boot.
Roxy looked at the ink.
"Hmm," she thought. "I have an idea!"
Roxy jumped to her feet and lifted up a bucket.
She tossed the ink into the air.
Then . . . Whoosh! Roxy blew the ink across the room.
The ink sprayed across the walls.
It sprayed across the machine.
And it sprayed across the Ghost Bandit!
"Aha!" cried Roxy. "I can see you now!"
