When I run, smoke whooshes out of my shoes. No one can see me, but I can see just fine. The smoke from my super sneakers gives me Zapato Power eyes. That means I can see things way down the block.
At the very end of the street, I saw something shiny and green.
I was there in half a blink, ready to face the girl on the green bike. But it wasn’t her. It was my friend Geraldo on a green scooter. He opened his mouth like a fish.
“Hey, Freddie! Did you just step out of that puff of smoke?”
Zapato Power is the best thing in the world. But keeping it a secret sometimes confuses my friends.
I raced off, leaving Geraldo on his green scooter with his mouth hanging open.
The next green thing I saw was over by the entrance sign to Starwood Park. I zoomed over, hoping it was the girl on the green bike. Instead, it was my next-door neighbor, Gio, pulling a green wagon.
“Look, Freddie! Puppy likes to ride!”
Gio’s little black dog, Puppy, stood in the wagon. 
Sometimes it takes more than superspeed to catch a crook.
Sometimes, you have to ask questions, too.
“Did you see a girl on a green bike?”
“Did she have black hair?” Gio asked.
“Yes,” I said. “When did you see her?”
“Right now!” Gio pointed over my shoulder. “Behind you.”
I turned around. The girl on the green bike was speeding past us.
She rode down the sidewalk fast, but that was no trouble for a guy with Zapato Power. In one blink, I was behind her, pushing a button on my wristband.
My super zapatos do more than run. They can jump—right over the girl on the green bike. As I sailed in the air, I looked down to see something very lucky.
The bike had a basket, and the pink wallet was sitting inside, ready for a Zapato Power rescue.
I landed and ran back toward the girl on the green bike. She only saw me for half a second. I grabbed the wallet and zipped off in a puff of smoke.
