David turned to meet the probing black eyes of Leader Marley. Just behind him were Dr. Lanza and Officer Magnun.

There was no time to conceal his mice, David realized. Shrugging into his jacket, he strode forward without hesitation, a smile on his face, and stretched out his hand.

"Leader Marley! This is indeed an honor. If you had only notified us of your visit, we should have been prepared."

"Young as ever, I see, Wong."

"Thank you, Leader." There was no banter in Marley's eyes, he noted, but he continued amiably. "It has been some years since you have honored us by a visit in person. I'm afraid a laboratory is not a very exciting place, but I'd be honored to show you anything that may be of interest to you."

A faint contempt curled Marley's mouth as he glanced around the room. "Nothing to see that I haven't seen before, is there? A lot of test tubes, a bunch of flasks, a mess of apparatus you'd think had been dreamed up by an idiot, and a bad smell. You still keep animals, I notice."

He sauntered over to the bench, picked up the cage and looked at the scurrying rodents.

David scarcely breathed.

Marley only nodded. "Well, mice are mice." He put down the cage and turned away. "These look just like the ones I saw when I was here eight or ten years ago. Same white patch on the forelimbs. I never knew mice could live that long."

"But—" began Lanza, bending over to study the mice.
