Like the Romans, Vikings, Scots, Saxons and, latterly, 15×15 Bloggers and Setters, what goes to York stays in York, so aside from this crossword blog much of what goes on behind the doors of the Fifteen Squared Annual General Assembly should remain secret. We should by now know whether there has been pillage and York has once again received a right sacking.
On to Cruciverbal matters, I have the pleasure of blogging the contribution from Cheeseman. A nicely accessible level of difficulty, with some lovely and well crafted clues.
