"Yes, sir," said Roger quietly. Then he added quickly, "I'd like the major to know, sir, that this is the first time this has happened."

"I have only your word for that, Manning!" Connel finally began blasting in his all too familiar roar. "Since you've done it once, I see no reason to think you couldn't have done it before or that you might not do it again!" The officer's face was now almost purple with rage. "When you've repaired that set, return to your quarters! You are confined until I decide on disciplinary action!"

Turning abruptly, Connel stormed out of the room, slamming the hatch closed behind him.

With a sigh Roger turned back to the set. With trembling fingers he reconnected the terminals and made delicate adjustments on the many dials. Finally, as power began to flow through the proper chain of circuits, the radar scanner glowed into life and the hair-thin line of light swept around the dull green surface of the scope. It had been left on a setting covering two hundred miles around the space station, and seeing the area was clear, Roger increased the range to five hundred miles. The resulting scan sent a sudden chill down his spine. A spaceship was roaring toward the station at full thrust!

Cold sweat beaded Roger's forehead as he grabbed for the microphone and called Tom.

"Radar bridge to control deck!" The words tumbled out frantically. "Tom! Tom! There's a ship heading right for the station! Bearing 098! Distance 450 miles! Coming in on full thrust! Tom, acknowledge! Quick!"

Down on the control deck, Tom had been watching a space freighter easing out of the station when Roger's voice came over the speaker in a thin scream.

"What?" he yelled. "Give me that again, Roger!"

"Spaceship bearing 098—full thrust! Range now four twenty-five!"

"By the craters of Luna," shouted Tom, "why didn't you pick her up sooner, Roger?"
