Yea my first thought was Call to Mind, but if Path clue is Track or Trail, it either starts with K or L (the last letters of this clue). Also I had PROTECTING for 12a - Defending, so that last letter G gives the third letter in the clue I need. thanks everyone for your quick responses.
Think I have it sorted. Was wrong in thinking of TO MIND as part of the clue, so here goes.....
Path is TRACK
Clue down is Keep in Mind, so made a few tippex adjustments.... and ready for envelope!
Thanks everyone for inspiration and support.
