“Look at it, or you’ll be seeing yourself on the evening news. ‘Doctor performs experiments with untested South American drug on accused mass murderer Brady Hartsfield.’”

Babineau stared at him with his mouth open, at that moment looking very much as he would after Brady began to whittle away his core consciousness. “I have no idea what you’re talking about.”

“I’m talking about Cerebellin. Years away from FDA approval, if ever. I accessed your file and took two dozen photos with my phone. I also took photos of the brain scans you’ve been keeping to yourself. You broke lots of laws, Doc. Look at the game and it stays between us. Refuse, and your career is over. I’ll give you five seconds to decide.”

Babineau took the game and looked at the swimming fish. The little tune tinkled. Every now and then there was a flash of blue light.

“Start tapping the pink ones, doctor. They’ll turn into numbers. Add them up in your head.”

“How long do I have to do this for?”

“You’ll know.”

“Are you crazy?”

“You lock your office when you’re not here, which is smart, but there are lots of all-access security cards floating around this place. And you left your computer on, which seems kind of crazy to me. Look at the fish. Tap the pink ones. Add up the numbers. That’s all you have to do, and I’ll leave you alone.”

“This is blackmail.”

“No, blackmail is for money. This is just a trade. Look at the fish. I won’t ask you again.”

Babineau looked at the fish. He tapped at a pink one and missed. He tapped again, missed again. Muttered “Fuck!” under his breath. It was quite a bit harder than it looked, and he began to get interested. The blue flashes should have been annoying, but they weren’t. They actually seemed to help him focus. Alarm at what this geezer knew started to fade into the background of his thoughts.

He succeeded in tapping one of the pink fish before it could shoot off the left side of the screen and got a nine. That was good. A good start. He forgot why he was doing this. Catching the pink fish was the important thing.

The tune played.

One floor up, in Room 217, Brady stared at his own Zappit, and felt his breathing slow. He closed his eyes and looked at a single red dot. That was Z-Boy. He waited . . . waited . . . and then, just as he was beginning to think his target might be immune, a second dot appeared. It was faint at first, but gradually grew bright and clear.

Like watching a rose blossom, Brady thought.

The two dots began to swim playfully back and forth. He settled his concentration on the one that was Babineau. It slowed and became stationary.

Gotcha, Brady thought.

But he had to be careful. This was a stealth mission.
