Politicians, the press and the police
Politicians, the press and the police.
Together they have become the Bermuda Triangle into which reputations have simply disappeared.
After cash for honours, came the arrest of a Tory MP who'd received leaks and passed them to the papers. After the scandal of MPs' expenses comes today's row about who knew what about the hacking of the phones of the great and the good and the merely famous.
But today Yates of the Yard decided that he did not want another starring role on the national political stage.
His insistence that there was no evidence that John Prescott's phone was tapped, insufficient evidence to bring other prosecutions and that no new evidence had been produced by the Guardian, sounded pretty definitive but these waters are still treacherous.
There will still be a Commons enquiry and there will be calls for an independent investigation into the police's handling of this affair.
There will still be awkward questions for News International, for the Tories' Director of Communications Andy Coulson and for the man who hired him David Cameron.
This is a story fuelled by genuine outrage at abuses by the press and politically inspired protests designed to damage the Conservatives.
The Tory leader is hoping that beyond the triangle of Westminster, Wapping and Scotland Yard few will be paying too much attention and that he can hang on to the Director of Communications - the former editor of the News of the World - who he values so much.
