The
minute I came home from school my brother, Manny, ran toward
me. I heard it again! I heard it again! he shrieked.
You heard what?
Footsteps! Doors opening and closing! Theres someone upstairs in apartment 4-B.
Manny was at it again. Theres no one in apartment 4-B, I said. The Morgans are on vacation.
Exactly! Manny cried. So whos walking around above us? A burglar? A spy? Maybe its a space alien!
I rolled my eyes. Ever since last weekend when we saw the movie Alien Creatures Attack, Manny thinks creatures from another planet have invaded.
Its probably just Sammy pouncing around, I said. Sammy was short for Samantha, the Morgans cat.
It cant be Sammy! Manny insisted. Cats dont pound the floors or slam doors. Weve got to find out whos upstairs!
Correction, little brother. You find out whos upstairs. I have soccer practice. I turned and walked away, wondering if Manny was really the one from another planet.
But that night something strange happened. The full moon glowed so brightly that an eerie beam shone across my darkened bedroom. Thats when I heard it. Footsteps above me, walking across the floor of apartment 4-B. Then a door creaked open and shut. My body froze.
Manny bolted into my room. Did you hear it? Did you hear it? he cried.
Ssh! I whispered. Mom will hear you.
I sat up and tried to think. Maybe a friend is staying in the Morgans apartment while theyre away.
Im going to hide out under the stairs tomorrow, Manny said, not listening to me Ive got Moms old camera. Im going to catch the alien in action!
Wait a minute, I said. First we should ask their neighbors upstairs. Somebody must have seen someone going into the Morgans apartment.
Not if theyre space creatures! said Manny. They could change into something else. They could become invisible. They could be plotting to destroy us right now!
Would you forget about that movie? I said. Tomorrow well ask Mom if we can talk to the neighbors. Now go back to sleep!
Manny
grinned and rubbed his hands together. Thats the way
he acts when hes on one of his personal missions to
save the earth.
As he walked out of my bedroom, I called to him, Leave my door open. And turn on the hall light, too!
Mom said we could talk to the neighbors upstairs if we were polite. So early on Saturday, Manny and I knocked at the door of apartment 4-A. Mrs. Cooper worked at home most of the day. She would know if anything strange was going on.
When she answered the door I asked, Have you seen anyone going into apartment 4-B since the Morgans left? A relative? A friend, maybe?
A space alien? Manny injected.
I jabbed him with my elbow.
Oh no, she said. Its been very quiet all week.
We thanked her and moved on to apartment 4-C.
Mr. Jacobs, a construction worker, opened the door. Im at the new building site most of the day, he said. But I havent noticed anyone strange going into the Morgans apartment.
We
thanked him and moved on to the last apartment on the floor-4-D.
Billy Klein, a high-school kid, answered our knock. Nobody
new on this floor, he told us.
A chill ran down my spine. If none of their neighbors had seen anyone, who was walking around the Morgans apartment?
A half-hour later, Manny had staked out a spot underneath the fourth-floor staircase.
What are you doing now? I asked.
Manny aimed Moms camera at me. Im going to shoot the alien upstairs.
What is it with you? There are no aliens living upstairs!
Exactly!
Theyre not living there, but theyre spying on
us, just like in the movie.
I shook my head. But suddenly images of hairless, one-eyed
aliens popped into my mind. I sat down next to Manny.
Noon passed. One oclock, then two. Manny read his Space Creatures comic books and lurched toward the steps every time he heard a noise. I tried going over soccer plays in my head, but movie scenes of attacking alien armies kept distracting me.
Finally,
at 3:57, we heard footsteps above us and a door opening.
We craned our necks over the banister and looked up the
stairs. The door to apartment 4-B was open! No one had passed
us on the stairsand theres no elevator in our
building.
My heart pounded as we raced up the stairs. Manny peeked
into the apartment.
He aimed the camera. But then a familiar voice saidHi, kids. Come to see Sammy?
Mr. Jacobs walked toward us from the pantry, his heavy construction boots pounding across the hardwood floor.
There you go, girl, Mr. Jacobs said, spooning food into the cats dish.
Mr. Jacobs looked at us. Sammy has some appetite. The Morgans asked me to feed her twice a day, but I think shed prefer three times. He petted Sammy. See you later, girl.
Afterward, alone with Manny downstairs, I muttered, Well, alien buster, Mr. Jacobs is some space creature!
Manny shrugged. But did you see how Sammy attacked that food bowl? I never saw her eat so much. Mannys eyes suddenly flashed. Maybe that wasnt really Sammy! he cried. I bet it was really an alien! I bet all the aliens have changed shape, and theyre waiting to attack the planet!
I winced and shook my head. Not again, Manny! I said. You just dont quit.
Manny rubbed his hands together and grinned. Exactly.
