Today's workout for the brain

This puzzle page kept me occupied for most of the afternoon and that was before I started on today's 'Super Fiendish' sudoku from The Times daily block. It remains a work in progress...

Thank goodness for some light relief when Nancy came in for coffee and shortbread.

All being well I'm heading down to Troon tomorrow to visit bestie Gill for a couple of days. I'm hoping for some beachy blips, but that'll depend on the weather.

PS  I'm stuck on 25 down in The Wee Stinker: "Cavities in cant-rails" -
5 letters : A-A-A  Any suggestions?
