Have seen esne the slave, hitherto unknown, somewhere just recently. Other dnks were those tiles (the singer a faint bell, his group not), and Swaledale which I cqba working out. Eccles is good at surface narratives, those for heavenward and up one’s sleeve were faves. Ta E and BnJ.
Re 23d, the book’s original title is Alice’s Adventures in Wonderland, which makes the definition a little clearer.
Happy to meet Eccles on any day of the week; thanks to him and to B&J.
Supremely enjoyable as always from this setter, with super-smooth surfaces the icing on the cake. 1a made a brilliant start and the fun carried on from there.
My only NHOs today were ESNE and SWALEDALE but both were very fairly clued.
Many thanks to Eccles and to B&J.
