"Detective Smith is missing," Roxy thought.
"I have to get to police headquarters."
She called to her friends. "Don't wait for me.
I, um, dropped something!" Roxy ran off.
The parking lot at police headquarters was empty.
"Where are all the police cars?" Roxy said.
"And where is everyone?"
When she went inside, Roxy blinked in surprise.
All the walls were crooked, and the floors were slanted.
"What happened in here?" Roxy said.
"It's like a fun house at an amusement park!"
A hallway was lined with mirrors.
One mirror made Roxy look tall and skinny.
Another one made her head look enormous.
Roxy made her way to the break room.
The coffeemaker was on, and cookies sat on the counter.
Music played on a radio.
But nobody was there.
Roxy scratched her head. "This is odd."
Click . . . Ba-doom!
The floor tilted under Roxy's feet, and she slid down into darkness.
"Oof!" Roxy landed on a hard floor.
"Rocket Girl?" It was Detective Smith.
Using her night vision, Roxy saw she was in a concrete room.
The detective stood near her.
Other police officers were in the room too.
Roxy grinned. "Are you all playing hide-and-seek?"
Detective Smith looked annoyed.
"This isn't funny, Rocket Girl. We've been stuck down here since yesterday!"
Roxy gulped. "Oh . . . Sorry to hear that.
What happened to the building? It's like a fun house."
"We hired a builder to make some improvements." Detective Smith sighed.
"Obviously he did a terrible job.
We can't even use the building now."
"Who is the builder?" Roxy asked.
"His name is Jack Hammer," Detective Smith said.
"We won't hire him again."
Another police officer walked over.
"How will we get out of here?" she asked.
Roxy laughed. "That's easy."
She flew the police officers up to the break room.
Detective Smith grabbed a cookie and took a bite.
The police dispatcher saw a light flashing on the phone.
"Yikes!" she said. "We have messages."
She played the first message.
"Hello? I'm worried about my friends Brenda and Dan Dooley.
They moved into their new house yesterday.
It's at Ten Puddle Lane.
I tried calling and knocking on their door, but there's no answer."
Other people had called with similar messages.
Many of them had called more than once.
Detective Smith swallowed the last bite of his cookie. "Oh boy."
