What began as a story about what was really said became a story about who leaked a police log but it is now much more serious than that.
The Metropolitan Police say they are investigating allegations against a serving police officer of fabricating evidence against someone who was, at the time, a cabinet minister. What's more, they say that they will investigate conspiracy if any evidence emerges.
Who cares whether Andrew Mitchell did or did not say "plebs" when he had an angry confrontation with police officers on the gates of Downing Street?
That's the reaction of some to the news that a police officer has been arrested for misconduct in a public office. He also claimed that he witnessed what happened, even though the Metropolitan Police Commissioner Bernard Hogan-Howe said this morning that he "wasn't there at the time"
The police watchdog - the Independent Police Complaints Commission (IPCC) - is investigating "the validity" of a claim made by a police officer whose evidence helped lead to the resignation of Andrew Mitchell as the government chief whip.
Mr Mitchell resigned after he apologised for swearing at an officer who refused to open the main gates of Downing Street to let the chief whip through on his bicycle.
It's time people saw how the coalition's sausages are made. That, believe it or not, is how Nick Clegg describes his latest strategy.
The deputy prime minister believes it's time the public understood that policy-making in government is like a kitchen in which all sorts of recipes are suggested, but only some make it onto the menu. He wants voters to know which ingredients the Lib Dems added and, just as importantly, which they insisted were left out.
It is a year since the prime minister found himself isolated in Europe at a summit determining the EU's future. It is six months since he signalled that he might be open to a referendum on Britain's relationship with the Europe. Yet David Cameron has still to fix a date let alone finalise the text of a long promised speech spelling out his European policy.
I understand the PM held a meeting with the foreign secretary and the chancellor on Monday to agree the content of a speech which will see him walking a political and diplomatic tightrope.
"I can tell the House that we are no closer to balancing the books than when we first promised to do it. We are not on course to meet our debt target. We now need to put up taxes and cut spending until at least 2018. We're making progress. We're sticking to our Plan."
Cue Tory MPs shouting "hear, hear" as the chancellor sits down to be congratulated by the prime minister.
This is a statement the chancellor would rather not have to make.
George Osborne will have to publish grim official forecasts with serious political and economic consequences. With growth much lower and borrowing much higher than he hoped, the chancellor may be forced to admit he's missing his own deficit and debt targets.
Tomorrow's a day the chancellor isn't looking forward to. It's the day he'll be unveiling official forecasts showing borrowing and debt both going up. The day he'll announce deeper cuts and more tax rises.
So on the morning before the bad news to come the prime minister and his deputy went to school to unveil what they hoped would be viewed as some better news - an increase in investment spending paid for by deeper cuts to day to day departmental budgets.
Newspaper editors and proprietors had hoped that this morning's meeting with the prime minister and the culture secretary would be in the House of Commons, allowing them to slip in to the building unnoticed.
It has, though, been switched to Number 10, turning their on-camera arrivals into what the editor of the Telegraph, Tony Gallagher, jokily described on twitter last night as "the perp walk" during which the TV guys would "shout rude questions as we humbly beg entry".
It should not be acceptable that it (the press) uses its voice, power and authority to undermine the ability of society to require that regulation is not a free for all, to be ignored with impunity. The answer to the question who guards the guardians should not be "no one".
Those words buried deep in the Leveson Report seem to summarise the judge's view.
The EU is trying to cook up a "Goldilocks budget" - not too hot for the countries like Britain, the Netherlands and Sweden who want to see spending frozen and not too cold for the countries of the South (Spain, Portugal, Greece) and East (led by the biggest net beneficiary Poland) who want to see spending on them maintained.
Yesterday's late night talks lasted little more than an hour and showed no sign of finding that recipe. One British source told me that the man in the chair, the President of the European Council Herman Van Rompuy, doesn't have a plan and doesn't have a way to get there. The necessary preparatory work had not been done I was told.
