PeeDee, the golfer in 10a is Ernie not Bernie.
Quite right Hovis. Thank you.
Very enjoyable. Ideal for breakfast in bed on Sunday. Thanks Hypnos and PeeDee.
A very welcome return of this setter. Particularly liked 11a & 4d plus the mention of my favourite detective who, perhaps coincidentally, returns to our screens tonight in a new series.
Many thanks to Hypnos and to PeeDee for the review.
Accidentally got ‘RIDGE’ by parsing porRIDGE (= bird or time in prison) less ‘por’ !
Great fun from start to finish.
Many thanks to Hypnos and to PeeDee.
We didn’t find this too difficult, although our first few entries – IMPISH, HISTORIC and NICHE were tentative until confirmed by crossing letters. Favourite was WATERTIGHT.
Thanks, Hypnos and PeeDee.
