I said carefully, “If it turns out that you’ve been infected with a bioweapon – and if you become too sick to work – is there anyone else who could interpret these results, and put the whole thing together?”

Mosala recoiled. “What are you asking me to do? Anoint a successor to be targeted next?”

“No! But if your TOE is completed and announced, the moderates will have to admit that they’ve been proven wrong – and there’s a chance they might hand over the antidote. I’m not asking you to publicize anyone’s name! But if you can arrange for someone to put the finishing touches—”

Mosala said icily, “I have nothing to prove to these people. And I’m not risking someone else’s life, trying.”

Before I could pursue the argument any further, De Groot’s notepad chimed. The head of security for the conference, Joe Kepa, had viewed the copy De Groot had sent him of my call from the fishing boat, and he wanted to talk to me. In person. Immediately.

In a small meeting room on the top floor of the hotel – with two large umale associates looking on – Kepa grilled me for almost three hours, questioning everything right back to the moment when I’d begged SeeNet to give me the documentary. He’d already seen reports from some of the farmers about events on the ACs’ boat (they’d posted their accounts directly onto the local news nets), and he’d seen the cholera analysis – but he was still angry and suspicious, he still seemed to want to tear my story to pieces. I resented the hostile treatment, but I couldn’t really blame him. Until the seizure of the airport, his biggest problem had been buskers in clown suits; now it was the threat of anything up to a full-scale military engagement around the hotel. Talk of information theorists armed with amateur bioweapons targeted at the conference’s highest profile physicists must have sounded like either a sick hoax, or proof that he’d been singled out for divine punishment.

By the time Kepa told me the interview was over, though, I believed I’d convinced him. He was angrier than ever.

My testimony had been recorded to international judicial standards: each frame stamped with a centrally generated time code, and an encrypted copy lodged with Interpol. I was invited to scan through the file to verify that there’d been no tampering, before I electronically signed it. I checked a dozen points at random; I wasn’t going to view the whole three hours.
