I think so: "held short" is not a phrase I'm familiar with, and "is low" is not a "normal" anagram indicator.
I tend to start with the answer, and work from there.
So "THRESHOLD" ... hmmm, that's an anagram of THE LORDS H, so perhaps I'd be looking at "something something the Lord's Hospital" maybe, and trying to find a definition of "THRESHOLD" with nine letters to throw people off the anagram scent?
