"The Jealous Reporter" section is entirely about this. Start from "But the judges and the experts could not tell the tapes apart."
In particular:
>The reporter who had gotten the exclusive story had been convinced at the time that Mick Ali knew the secret, but the reporter could not pass his conviction on to the judges in court or to the television audiences either.
>Mick Ali had achieved his real objective. He wanted, in fact, to show that it is possible to convince without revealing, and so without unveiling his secret.
