Yep, Helena and John. Just for your confidence, they've already been solved and passed by my expert critic. I'll just post the occasional ones to add a little something (I hope!) to this excellent site. I'm off to my virtuous couch now. 'night!
Big Dave 1 & 2 (+); Aljanon 3 and Helena 4. Great!
Hope you found 'em enjoyable. I'd love to put up an occasional similar thread, if that's OK. Happy New Year to all.
