Infrared equipment went on again, and the eerie illumination spread over their surroundings. Malone tapped Boyd on the shoulder and jerked his thumb toward the back stairs. This was plainly no time for talk.

From the floor above, they could hear the murmur of youthful voices.

They started for the stairway. Fortunately, the building was of the steel-and-concrete type; there were no wooden floors to creak and groan beneath their feet.

At the bottom of the stairs, they paused. Voices came down the stairwell clearly, even words being defined in the silence.

"... And quit harping on whose fault it was." Malone recognized Mike Fueyo's voice. "That FBI guy

was on to us and we had to pull out; you know that. We always figured we'd have to pull out some day. So why not now?"

"Yeah," another voice said. "But you didn't have to go and vanish right under that Fed's nose. You been beating into our heads not to do that sort of stuff ever since we first found out we could make this vanishing bit. And then you go and do it in front of a Fed. Smart. Sure, you get a big bang out of it, but is it smart? I ask you—"

"Yeah?" Mike said. "Listen, Silvo, they never would've got onto us if it hadn't been for your stupid tricks. Slugging a cop on the dome. Cracking up a car. You and your bug for speed!"

Malone blinked. Then it hadn't been Miguel Fueyo who'd hit Sergeant Jukovsky, but Silvo. Malone tried to remember the list of Silent Spooks. Silvo ... Envoz. That was it.

"You slugged the FBI guy, Mike," Silvo said. "And now you got us all on the run. That's your fault, Mike. I want to see my old lady."
