In full, there is a type of fish called a sawfish, so I guess it can be referred to as just a 'saw' with 'saws' as the plural. Hark = pay attention, so a sawshark is a large fish.
Shed is a Guardian setter and the answer is shouted (not a themed clue) 6d is bass (fish) + hark with one of the themed words put into the middle to make a kind of shark.
I'm struggling with 15a - have ?A?A?S? and wondering which of the themed words fits.
Oh, dear! Thanks for that, PJW...I wondered why I'd found two of every OTHER theme-word but the one you have now offered. Ah well, no prize for ME this week!
Thanks all.
I have the all the answers but still 6d, 18d, 23d and 26 d as themed clue. So I am missing one. The one which is a real word without the themed word added to it.
Thanks to Lie-in King to try and help me so early in the morning. I am across the pond so 6 hours behind.
