Solvers! Just a quick note to say I'll be abseiling down the iconic Forth Bridge in Scotland to support Sense Scotland, a charity providing support to people with complex sensory disabilities. If you can spare some change, your generosity would be amazing: https://gofund.me/32af5532
I suspect this may prove a difficult one, and I can only apologise where this difficulty stems from shortcomings on the part of your humble setter. I'll do my best to justify my transgressions in the wash-up below.
ACROSS. 1A5D. "Divorce" = SPLIT + "results" = ENDS.6A. Homophone of "heavy metal" = LEAD.8A. Reversal of "clergyman" = DEAN around "king" = K.9A. "A" plaintext, preceded by "note" = TE.10A. Insertion of "fuel" = OIL in "vessel" = SS.
DOWN. 2D. To be parsed as "object subject verb": "soldiers" = PLATOON minus "active" = ON.3D. "tuber gives out cards" = I DEAL.4D. Subtraction of "drugs" = E/E from "make psychedelic patterns appear" = TIE-DYE.7D. Hidden in "weEKEnd."
Once again, if you've enjoyed the puzzle, and if you can, please sign up at https://gofund.me/32af5532 to give some money to charity (all donations will go to Sense Scotland, and I will cover all associated fees.)
