It turned all their gazes upon me. I was up on one elbow. "What I know about what?" I said.


Torio leaped to his feet and stood bending over me. "Now then, you damned crime-tracker. Where is the T-catalyst? It's hidden around here somewhere. Where is it?"

"Catalyst," I mumbled. "I don't know what you mean."

Torio's foot kicked savagely at me. I tensed; the giant Mokk shifted his weapon to level down at me. I saw Mackensie flash me a glance.

"So you're going to try that too?" Torio rasped.

I stared. "He doesn't know any more about it than I do," Mackensie growled. "Nobody knew except Georg Blake, and you killed him. Find it for yourself. My guess it that Blake cast it adrift when the attack came."

"You talk without sense," Mokk put in. "Maybe the girl knows." He chuckled. "If you leave me alone with her, Torio, I can think of ways to make her tell."

"I know nothing about it," Nina gasped.

"Well, some one of you does," Torio said grimly. "We'll start with this damn crime-tracker." He leaped across the room, came back with a length of wire. My gaze strayed to the opposite wall; the treasure was there, back of a secret panel.
