Some may need a delicate tweak (with an eye to surface story, or surplus words) to go from good to gold.

DADA: Anti-art breaking old adage

Thanks for the dazzling trios - as well as two sensational [kinda late] submissions.

But since Crucifer is UK-based, and Sam is still waiting for a delayed book prize from October (the publisher's lag, not mine), then I will accept the latecomers just this week.

Great comp, again. Wrap & results on Saturday.

Thanks DA, and now I've had a coffee, I can throw it into the ring...

Tweak...

TARTAR: Rodent repeatedly sent back wine byproduct

Oops. I missed the reference to a deadline. I'm new round these parts, you know... ;)

@crucifer: Da gave you a green light. So "CHOP CHOP".
