Hi again Susan,
Looks good to me!
That was the last across clue. the first was:
Rehearse murder with sword (3,7)
Got that first thing this morning: RUN THROUGH.
3 down is: Control such as Nelson far too much (4,4,4)
Letters: H - - - / - - a -/ - - - -
Doing a bit of guessing, I'm wondering if it is HALF HEAD LOCK. Am I close?
ETA: 12 across is: Circling a lake with my waterproof footwear (6)
I have been thinking 'galoshes' of course, and find there is a singular - galosh.
However, that makes the first letter of the second word of the (4,4,4) answer begin with S, so obviously I'll have to think again..
