A firm offer from Cameron?
From David Cameron, then, an offer of more tax powers for the Scottish Parliament within the United Kingdom. An offer which is designed to resonate in the referendum debate - but which was also aimed at representatives in the hall for the Scottish Conservatives conference.
The prime minister went further than before in endorsing the enhancement of devolution. Quite deliberately, he described himself as agreeing with the party's Scottish leader Ruth Davidson.
Why? Two reasons. One, to underline her status. Two, to pre-empt any grumbling from the elegantly mown grass roots of the Tories about going further down a devolutionary path which they didn't much fancy in the first place. It is no coincidence that their loudest applause was for any reference to "our United Kingdom."
Strictly speaking, his offer was couched in terms that might be viewed as conditional. He described the choice facing people at the referendum thus. "Vote 'Yes' - that is total separation. Vote 'No' - that can mean further devolution. More power to the Scottish people and their parliament, but with the crucial insurance policy that comes with being part of the UK."
The wicked media instantly pounced upon that word "can". (It's part of our charm.) We were assured, repeatedly, that the PM meant "will": that he intended this to be a certain offer.
A biblical day at Holyrood
Sundry sources were cited at Holyrood. They could scarcely have been more diverse. Willie Rennie quoted the Bible. Alex Salmond quoted the Daily Record. Johann Lamont quoted herself.
As is only proper, let us begin with scripture. Mr Rennie, he of the Liberal Democrats, said that, as in the Book of Daniel, the first minister had been measured and found wanting - with regard to Scotland's balance sheet.
Where politics meets statistics
Alex Salmond's demeanour was modest, contained and controlled - with the occasional dry quip lobbed in the direction of the wicked media who were questioning him about GERS.
(No, not the outfit who may or may not make it to the cup semi-final to face doughty opponents. We are talking about the Government Expenditure and Revenue Scotland report.)
Scottish independence: Brown outlines 'more powers' offer
We learned rather a lot today from Gordon Brown. We learned that he can still deliver a detailed, thoughtful speech ad lib while striding back and forward across the platform, restless like a caged but powerful lion.
We learned what I suspect will be the framework of the Labour offer on more powers for Holyrood when the party's commission reports next week, prior to conference.
Scottish independence: Gordon Brown outlines 'power-sharing' UK
Mr Brown delivered his speech in a church hall in Glasgow's East End, enabling him to recall a few gags from his days as a son of the Manse in the Dear Green Place.
But his approach was decidedly serious. The UK, he said, required to be effectively recalibrated, shedding the lingering image of solitary centralism.
First ministers questions: government accused on justice reform
There he sat, silent and lugubrious. All around him, his accusers demanded his head - or at least a stiff sentence of community work.
His name? Kenny MacAskill. His designation? Justice secretary. His crime? Steering a piece of Scottish government legislation through a decidedly sceptical chamber.
Scottish independence referendum: All, or something?
It is emphatically not the case that the focus will shift entirely away from the independence offer. But, equally, it is important that the alternative proposals for Scotland's future receive a fair deal of attention - and scrutiny.
Nicola Sturgeon decided to retaliate first - by suggesting that her opponents' ideas, both extant and emerging, fall short of Scotland's requirements.
