"Seventeen, one, Achernar, Canopus...."
"Check...."
Check, check, CHECK!
"Nineteen, three, Capella, Regulus, Alpha Centauri.... Nineteen, four...."
"Hold it! Wait a minute, Mr. Tremaine. If you draw a line from Capella through Regulus to Centauri, what else should you cross?"
Alan looked at his map. "You come close to Castor and Pollux, close to Cancer, you cross the constellations Crater and Corvus."
"Not out here, you don't."
Then Alan was running to the viewport. Between bright, unblinking Regulus and even brighter Alpha Centauri was—nothing. A hole in space. A long, narrow path of intense, unbroken blackness.
"That's it!" Alan shouted. He felt like laughing, like pounding the man's back, like dancing a jig. They had found the space-warp.
Alan ran to the pilot chair, swinging the small ship around almost ninety degrees. In the rear viewscreen he could see the five other ships wheeling about and following.
