it comes!â Mr. Vaslov smiled as the walls of the toolshed started to shake.
I waved a quick goodbye and headed out the door.
The purple sneakers made a soft buzzing sound. My feet felt light. I ran faster and faster until the grass was just a blur beneath me.
Smoke whooshed out of my heels. The wind whipped across my cheeks. My legs whirled so fast I could hardly see them.
But I could see the train. It was up there beside me, falling behind! And I was zooming ahead, like a supercharged engine in my purple sneakers. Rápido! My pretend game had turned real! I was as fast as an airplane, racing the train. And winning!
When I got to the station, I dropped to the ground behind the fence. The train roared in over me. Iâd just run a whole mile in a few seconds!
Talk about Zapato Power! I looked down at my purple sneakers. They were super shoes. I had super power! Where did Uncle Jorge get shoes like this? How fast could I get home to call him?
I stood up and spread out my arms.
My feet took off like jet wheels on a runway. One blink later, I was back at 29G.
3. The Mysteries Begin
âGracias!â I shouted into the phone. âThank you!â
âYouâre welcome,â Uncle Jorge said. âWhat did I do?â
âYou sent me Zapato Power! The fastest sneakers in the world!â
âSneakers?â Uncle Jorge repeated. âSorry. It wasnât me.â
If Uncle Jorge hadnât sent me the shoes, who had?
âSo what else is happening?â Uncle Jorge asked. âHowâs your head? You still keeping it short like a soldier?â
I laughed. Uncle Jorge always teased me about my hair. He said it made me look like my hero dad.
We talked a few minutes more. I told him about getting an A for the first time in spelling, and about the new basketball courts at school. Even though Iâm shorter than most of the other guys, I can still get the ball through the hoop.
âWatch the mail,â Uncle Jorge promised just before he said goodbye. âIâll get paid next week and send you something good.â
âThanks, Uncle Jorge.â I hung up the phone, still wondering where my purple sneakers came from.
Maybe Mom could tell me. I always called to tell her I got home all right anyway. She worked in a busy doctorsâ office, answering telephones. I munched on pretzels while I waited on hold, listening to music and an electronic voice telling me my call was important.
âDid you leave a box on the doorstep for me?â I asked when I finally got through.
âNo, Freddie.â Mom sounded puzzled. âI always leave things for you on the table.â
I knew that was true, but when youâre solving a mystery, you have to check everything out, even if it means saying mushy stuff to your mom on the phone.
âSee you at six, mi hijito.â
âLove you, too, Mom.â
Iâd made enough phone calls. It was time to investigate in other places.
âI need to look at the box,â I realized.
But it was still at Mr. Vaslovâs shed. I fed my guinea pig, Claude the Second, and left 29G, wearing my new purple sneakers. They felt like foam under my feet.
âMr. Vaslov!â I knocked on the toolshed door.
He opened it wearing safety goggles, like a scientist.
âIâm busy now, Freddie,â he said. âCan I help you later?â
âI need the box my sneakers came in.â
âWhy do you want that?â Mr. Vaslov pushed his goggles up.
âIâm trying to find out who gave me my purple sneakers.â
Mr. Vaslov scratched his face.
âFreddie,â he said. âJust enjoy the sneakers. Donât worry about where they came from.â
It was good advice, but Iâm a curious guy.
âPlease. Can you tell me where the box is?â
Mr. Vaslov pushed his goggles back down over his blue eyes.
âI put it out for the trash.â He closed the door.
Luckily, the box was beside the
