Puzzle of European law and On the Runs
Last week Northern Ireland Secretary of State Theresa Villiers made a speech declaring that the controversial administrative scheme for On the Runs is, so far as the government is concerned, over.
My guest on BBC Radio Ulster's Inside Politics was Deputy First Minister Martin McGuinness.
He told me he found the secretary of state's intervention "bizarre" given that Attorney General Dominic Grieve had described the scheme as lawful.
Mr McGuinness went on to argue that people had a right under European law to clarify whether or not they were wanted by the police.
The European law aspect of the On the Run story puzzles me. Away from the local context, you do not often hear about suspects phoning up the police just to check if the authorities are looking for them.
Bill Clinton soaks up political limelight in Londonderry
Much excitement in Londonderry as Bill Clinton takes a stroll across the Peace Bridge and heads to the Guildhall Square to address the public.
But if the European Commission President Jose Manuel Barroso, who is also visiting Ireland, walked the same walk, you can't imagine it generating anything like the same buzz.
On the Runs: Secret deal hidden in plain sight
The Police Service of Northern Ireland codenamed their processing of republican On The Runs "Operation Rapid".
The same nickname could have been applied to this week's fast moving political crisis.
'Good cops' in Sinn Féin and DUP outnumbered by 'bad cops'
Nothing new in the DUP and Sinn Féin trading insults or claiming each other is pandering to extremes.
But there seems to be an extra level of sophistication in the latest mirror image machinations between the two incumbents at Stormont Castle.
Scottish and EU referendums: The effect on Northern Ireland
While Northern Ireland's Deputy First Minister Martin McGuinness aims a few fresh barbs at First Minister Peter Robinson on the eve of another Sinn Féin Ard Fheis (annual party conference), others have been surveying the wider scene.
The Irish prime minister, Tony Blair's former chief of staff and the DUP MP for North Antrim have all been ruminating on what changes in Scotland or Europe might mean for Northern Ireland.
Stormont opposition no closer
Should Stormont have an opposition? That was a talking point back in 2012 when the Ulster Unionists were choosing a new leader.
John McCallister advocated taking the party out of the Northern Ireland Executive unilaterally. Mike Nesbitt argued there should be a referendum on changing the Stormont rules.
Ian Paisley and DUP: Politics 'red in tooth and claw'
So do you believe him then or do you believe him now?
Part two of Eamonn Mallie's documentary, From Genesis to Revelation, contains an extract from my interview with Ian Paisley when he announced his decision to stand down as first minister in March 2008.
Haass talks: Peter Robinson attacks 'dictator' McGuinness
This is another row with a distinct edge between the DUP and Sinn Féin.
What is different to some of the previous rows, where you got the impression that the main men in Stormont Castle had licensed their lieutenants to throw the odd rock at each other, is that this is happening between Mr Robinson and Mr McGuinness.
Why Ian Paisley is still box office - five and a half years after stepping down from politics
It may be five and a half years since Ian Paisley stood down as Stormont's first minister, but there is no doubt the 'Big Man' is still box office.
Watching him in conversation with Eamonn Mallie for Monday night's BBC documentary Paisley: Genesis to Revelation remains spellbinding, as the ex-DUP leader treats us to his full range from charming humour, through to belligerent defence of the apparently indefensible.
Unmistakeable taste of freshly-picked cherries
According to the Ulster Unionist leader Mike Nesbitt, Richard Haass gave the Stormont parties only three options with his final seventh draft document - say Yes, say No, or take it back to your party. But don't - according to Mr Nesbitt - cherry-pick.
Yet now we have all the party responses in, (assuming Sinn Féin's Ard Comhairle meeting will ratify their negotiators' acceptance), the taste of freshly-plucked cherries is unmistakeable.
