OK. I've found it, mj2c, and thank you SO MUCH for your fantastic patience !!
However, after all this messing, I think I'm going to have to delete it anyway
, and, in fact, uninstall the game, because the save is on my C Drive
[I'll just carry on and finish the game with the install I already have on my XP computer.]
My new machine has only a small solid state "C" drive - specifically for booting up at speed - and as it is purposely
only a small drive, I don't want to clog it up with games stuff.
My BIG drive - for games and everything else - is "D" and that's where I installed Sherlock and
where I've been doing all this fruitless (curses) searching !!
But a huge thanks to all who have been trying to help me.
I have appreciated your efforts VERY much and am most grateful.
What a shame for poor Moriarty, though. Getting blamed for something he hasn't done .... for once
