“Meanwhile the war continues as it is. Stalemate. Checkmate. They can’t get to us, and we can’t get through their living minefield.”

Kramer nodded. “It’s a perfect defense, for them. But there still might be one answer.”

“What’s that?”

“Wait a minute.” Kramer turned to his rocket expert, sitting with the charts and files. “The heavy cruiser that returned this week. It didn’t actually touch, did it? It came close but there was no contact.”

“Correct.” The expert nodded. “The mine was twenty miles off. The cruiser was in space-drive, moving directly toward Proxima, line-straight, using the Johnson Control, of course. It had deflected a quarter of an hour earlier for reasons unknown. Later it resumed its course. That was when they got it.”

“It shifted,” Kramer said. “But not enough. The mine was coming along after it, trailing it. It’s the same old story, but I wonder about the contact.”

“Here’s our theory,” the expert said. “We keep looking for contact, a trigger in the pseudopodium. But more likely we’re witnessing a psychological phenomena, a decision without any physical correlative. We’re watching for something that isn’t there. The mine decides to blow up. It sees our ship, approaches, and then decides.”

“Thanks.” Kramer turned to Gross. “Well, that confirms what I’m saying. How can a ship guided by automatic relays escape a mine that decides to explode? The whole theory of mine penetration is that you must avoid tripping the trigger. But here the trigger is a state of mind in a complicated, developed life-form.”

“The belt is fifty thousand miles deep,” Gross added. “It solves another problem for them, repair and maintenance. The damn things reproduce, fill up the spaces by spawning into them. I wonder what they feed on?”

“Probably the remains of our first-line. The big cruisers must be a delicacy. It’s a game of wits, between a living creature and a ship piloted by automatic relays. The ship always loses.” Kramer opened a folder. “I’ll tell you what I suggest.”
