I reached down and grabbed Akili by the front of vis jacket and sent ver sprawling backward onto the floor. Ve stared up at me, faking shock, anguish, bewilderment. I knelt down over ver and punched ver in the face, clumsily – surprised that I’d even got this far; I was no good at violence, and I’d expected ver to defend verself with all the agility ve’d demonstrated on the boat, long before I’d lain a finger on ver.

Sarah was outraged. “What are you doing? Andrew! ” Akili just stared at me – speechless, hurt, still playing dumb. I lifted ver half off the ground with one hand – ve barely resisted – then punched ver again.

I said evenly, “I want the antidote. Now. Do you understand? No more threats to De Groot, no files destroyed, no negotiations – you’re just going to hand it over.”

Akili searched my face, clinging to the charade, protesting innocence with vis eyes like some wrongfully accused lover. For a moment, I wanted to hurt ver badly; I had idiot visions of some bloody catharsis, washing the pain of betrayal away. But the thought of Sarah recording it all kept me in check; I never found out what I would have done, if we’d been alone.

And my rage slowly ebbed. Ve’d infected me with cholera, slaughtered three people, manipulated my pathetic emotional needs, used me as a hostage … but ve hadn’t, remotely, betrayed me . It had all been an act from the start; there’d never been anything between us to be sacrificed to the cause. And if the solace I thought we’d given each other had only been in my head, then so was the humiliation.

I’d live.

Sarah said sharply, “Andrew!” I glanced at her over my shoulder; she was livid, she must have thought I’d gone insane. I explained impatiently, “That call was from Karin De Groot. Violet’s dead. And now the extremists have threatened to kill me if De Groot doesn’t trash the TOE calculations.” Akili mimed grave consternation; I laughed in vis face.

“Okay. But what makes you think Akili’s working for the extremists? It could be anyone in the camp—”

“Akili is the only person besides me and De Groot who knew about Mosala’s joke on the ACs.”

“What joke? ”

“In the ambulance.” I’d almost forgotten; I hadn’t reached the end of the story for Sarah. “Violet programmed software to write up the calculations, polish the TOE, and dispatch it over the net. And the work’s all completed; De Groot only caught it before it was sent.”

Sarah fell silent. I turned to her warily, still expecting Akili to make a move once my guard was down.

She had a gun in her hand. “Stand up please, Andrew.”

I laughed wearily. “You still don’t believe me? You’d rather trust this piece of shit – just because ve was your source?”
