Lake's main contribution would be a lengthy book: terran spaceships; types and operation. He postponed its writing, however, to first produce a much smaller book but one that might well be more important: interior features of a gern cruiser. Terran Intelligence knew a little about Gern cruisers and as second-in-command of the Constellation he had seen and studied a copy of that report. He had an excellent memory for such things, almost photographic, and he wrote the text and drew a multitude of sketches.

He shook his head ruefully at the result. The text was good but, for clarity, the accompanying illustrations should be accurate and in perspective. And he was definitely not an artist.

He discovered that Craig could take a pen in his scarred, powerful hand and draw with the neat precision of a professional artist. He turned the sketches over to him, together with the mass of specifications. Since it might someday be of such vital importance, he would make four copies of it. The text was given to a teen-age girl, who would make three more copies of it....

Four days later Schroeder handed Lake a text with some rough sketches. The title was: operation of gern blasters.

Not even Intelligence had ever been able to examine a Gern hand blaster. But a man named Schrader, on Venus, had killed a Gern with his own blaster and then disappeared with both infuriated Gerns and Gern-intimidated Venusian police in pursuit. There had been a high reward for his capture....

He looked it over and said, "I was counting on you giving us this."

Only the barest trace of surprise showed on Schroeder's face but his eyes were intently watching Lake. "So you knew all the time who I was?"

"I knew."

"Did anyone else on the Constellation know?"

"You were recognized by one of the ship's officers. You would have been tried in two more days."
