"Lights!"

The lab dropped into darkness. Two flashes of light accompanied the last two shots from Wentz and then complete blackness set in. Pierce immediately rolled to his right again so he would not be in the same position Wentz had last remembered him to be. On his hands and knees he held perfectly still, trying to control his breathing. He listened for any sound that was not his own.

There was a low guttural sound to his right and behind him. It was either Renner or Zeller. Hurt. Pierce knew he could not call out to Renner, because it could help Wentz focus his next shot.

"Lights!"

It was Wentz but the voice reader was set to receive and identify only the top tier of the lab team. Wentz's voice would not do it.

"Lights!"

Still nothing.

"Six-Eight? There's gotta be a switch. Find the light switch."

There was no reply or sound of movement.

"Six-Eight?"

Nothing.

"Six-Eight, goddamnit!"

Again, no reply. Then Pierce heard a banging sound ahead of him and to the right. Wentz had walked into something. He judged by the sound that it was at least twenty feet away.

Wentz was probably near the mantrap, searching for his backup man or the light switch.

He knew it did not give him a lot of time. The light switch was not next to the mantrap door but it was only five or six feet away, by the electric control panel.

Pierce turned and crawled silently but quickly back toward the probe station. He remembered the gun Renner had found on Zeller.

When he got to the table he reached up and ran his hand along the top surface. His fingers dragged through something thick and wet and then they touched what he clearly identified as someone's nose and lips. At first he was repelled, then he reached back and let his fingers follow the face up, over the crown of the head until they found the knot of hair at the back. It was Zeller. And it appeared that he was dead.

After a moment's pause he continued the search, his hand finally clasping around the small pistol. He turned back in the direction of the mantrap entrance. As he made the maneuver his ankle clipped a steel trash can that was under the table and it went over in a loud clatter.

Pierce ducked and rolled as two more shots echoed through the lab and he saw two microsecond flashes of Wentz's face in the darkness. Pierce did not return fire, he was too busy moving out of Wentz's aim. He heard the distinct thwap thwap sound of the bullets meant for him hitting the copper sheeting on the outside wall of the laser lab at the end of the room.

Pierce tucked the gun into the pocket of his jeans so he could crawl more quickly and efficiently. He once more concentrated on calming himself and his breathing and then started crawling forward and to his left.

He reached out one hand until he touched the wall and gathered his bearings. He then crawled silently forward, using the wall as a guide. He passed the threshold to the wire room -he could tell by the concentrated smell of burned carbon -and moved to the next room down, the imaging lab.

He slowly stood up, his ears primed for the sound of any close movement. There was only silence and then a metallic snapping sound from the other side of the room. Pierce identified it as the sound of a bullet clip being ejected from a gun. He did not have a lot of experience with guns but the sound seemed to fit with what he was imagining in his head: Wentz reloading or checking the number of bullets he had left in his clip.

"Hey, Bright Boy," Wentz called out then, his voice splitting the darkness like lightning.

"It's just you and me now. Better get ready because I'm coming for you. And I'm gonna do more than make you put the lights back on."

Wentz cackled loudly in the darkness.

Pierce slowly turned the handle on the imaging lab door and opened it without a sound.

He stepped in and closed the door. He worked from memory. He took two steps toward the back of the room and then three to his right. He put his hand out and in another step touched the wall. With fingers spread wide on each hand he swept the wall -his hands making figure eight motions -until his left hand hit the hook on which hung the heat resonance goggles he had used during the presentation to Goddard that morning.

Pierce turned on the goggles, pulled the top piece over his head and adjusted the eyepieces. The room came up blue-black except for the yellow and red glow of the electron microscope's computer terminal and monitor. He reached into his pocket and pulled out the gun. He looked down at it. It too showed blue in the vision field. He put a red finger through the guard and pulled it in close to the trigger.

As he quietly pulled the lab door open Pierce saw a variety of colors in the central lab. To his left he saw the large body of Six-Eight sprawled near the mantrap door. His torso was a collage of reds and yellows tapering in his extremities to blue. He was dead and turning cold.

There was a bright red and yellow image of a man huddled against the wall to the right of the main computer station. Pierce raised the gun and aimed but then stopped himself when he remembered Rudolpho Gonsalves. The huddled man was the security guard Wentz had used to gain entrance to the lab.

He swept right and saw two more still figures, one slumped over the probe station and turning blue in the extremities. Cody Zeller. The other body was on the floor. It was red and yellow in the vision field. Renner. Alive. It looked like he had turtled backward into the kneehole of a desk. Pierce noted a high-heat demarcation on the detective's left shoulder. It was a drip pattern. The purple was warm blood leaking from a wound.

He swept left and then right. There were no other readings, save for yellow reactions off the screens of the monitors in the room and the overhead lights.

Wentz was gone.

But that was impossible. Pierce realized that Wentz must have moved into one of the side labs. Perhaps looking for a window or some sort of illumination or a place from which he could attack in ambush.

He took one step through the doorway and then suddenly hands were upon him, grabbing his throat. He was slammed backward into the wall and held there.

The vision field filled with the blaring red forehead and otherworldly eyes of Billy Wentz. The warm barrel of a gun was pressed harshly into the softness under Pierce's chin.

"Okay, Bright Boy, this is it."

Pierce closed his eyes and prepared for the bullet the best he could.

But it didn't come.

"Turn the fucking lights on and open the door."

Pierce didn't move. He realized Wentz needed his help before he could kill him. In that moment he also realized that Wentz probably wasn't expecting that he would have a gun in his hand.

The hand that gripped his shirt and throat shook him violently.

"The lights, I said."

"Okay, okay. Lights."

As he said the words he brought the gun up to Wentz's temple and pulled the trigger twice. There was no other way, no other choice. The blasts were almost simultaneous and came instantaneously to the lights in the lab suite coming on. The vision field went black and Pierce reached his other hand up and shoved the goggles off. They fell to the ground ahead of Wentz, who somehow maintained his balance for a few seconds, despite his left eye and temple having been torn away by the bullets Pierce had fired. Wentz still held the gun pointed up but it was no longer under Pierce's chin. Pierce reached out and pushed the gun back, until its aim was no longer a danger. The push also sent Wentz on his way.

He fell backwards onto the floor and lay still, dead.

Pierce looked down at him for ten seconds before taking his first breath. He then collected himself and looked around. Gonsalves was getting up slowly, using the far wall to hold himself steady.
