Thanks for that guys, it's one for the notebook. This one is a puzzle, I can only find a handful of options and none seem to match a possible definition.
Back in the are of town where soldiers reside(5,7) T?R?E ??????? - (Is it 'Three Estates')?
Thanks andyc. The thing is is I didn't think it was a place that was known for housing soldiers. Of course that could just be a ref. to the letters RE or OR or some such.
