The suedette suitcase—

Vanning worked it into the locker, breathing hard. It took a little time, since the valise was larger than the metal cabinet. But at last he relaxed, watching the brown case shrink and alter its outline till it was tiny and distorted, the shape of an elongated egg, the color of a copper cent piece.

“Whew!” Vanning said.

Then he leaned closer, staring. Inside the locker, something was moving. A grotesque little creature less than four inches tall was visible. It was a shocking object, all cubes and angles, a bright green in tint, and it was obviously alive.

Someone knocked on the door.

The tiny—thing—was busy with the copper-colored egg. Like an ant, it was lifting the egg and trying to pull it away. Vanning gasped and reached into the locker. The fourth-dimensional creature dodged. It wasn’t quick enough. Vanning’s hand descended, and he felt wriggling movement against his palm.

He squeezed.

The movement stopped. He let go of the dead thing and pulled his hand back swiftly.

The door shook under the impact of fists.

Vanning closed the locker and called, “Just a minute.”
