A telepathic transmitter; use of a living plasma that had been discovered on Luna. He shuddered with self-aversion. The thing lived inside him, within his own brain, feeding, listening, feeding. But the Interplan police used them; that had come out even in the homeopapes. So this was probably true, dismal as it was.

“Why me?” Quail said huskily. What had he done—or thought? And what did this have to do with Rekal, Incorporated?

“Fundamentally,” the Interplan cop said, “this has nothing to do with Rekal; it’s between you and us.” He tapped his right ear. “I’m still picking up your mentational processes by way of your cephalic transmitter.” In the man’s ear Quail saw a small white-plastic plug. “So I have to warn you: anything you think may be held against you.” He smiled. “Not that it matters now; you’ve already thought and spoken yourself into oblivion. What’s annoying is the fact that under narkidrine at Rekal, Incorporated you told them, their technicians and the owner, Mr. McClane, about your trip—where you went, for whom, some of what you did. They’re very frightened. They wish they had never laid eyes on you.” He added reflectively, “They’re right.”

Quail said, “I never made any trip. It’s a false memory-chain improperly planted in me by McClane’s technicians.” But then he thought of the box, in his desk drawer, containing the Martian life forms. And the trouble and hardship he had had gathering them. The memory seemed real. And the box of life forms; that certainly was real. Unless McClane had planted it. Perhaps this was one of the “proofs” which McClane had talked glibly about.

“We not only know you went to Mars,” the Interplan cop agreed, in answer to his thoughts, “but we know that you now remember enough to be difficult for us.
