Hi all. My first 'contribution' this time. I haven't read everything but dipped in over the weekend. I remember drawing stepped buildings beginning with z at primary school many years ago so am sure I have that OK but I can't parse it (or find where to put it.) This is definitely not my favourite sort of puzzle. I like the ones where the difficulty is in being led to think one way and then realising that the 'pop singer' you have been looking for is not a pop singer but that pop is lemonade or Dad or that the singer is a sewing machine - ones where you I think 'O YES, of course!' not, after loads of googling 'Oh I suppose it has to be that although I've never heard of it but it's the only word that fits.'
So, I need help, please. Is the thematic G at 1 Down or much further down ending in the non-thematic J? Is the non-thematic N in the bottom left quarter, cutting across the thematic C and the non-thematic D? Does the thematic E end in the non-thematic 4 letter L?
Oh, and where can I put my stepped building? Thanks for help with any of this.
