This puzzle is from the August 2023 Elkstone Newsletter.
It can be completed online simply by selecting a clue in the right panel (which is scrollable), and the squares to be completed in the grid will be highlighted. Buttons in the left hand column allow you to check an entry, or reveal a letter, or revert (reset) the whole puzzle. The Solution button will show all the correct answers, but note that this is irreversible – unless you click the Reverse button to start again!
