Brilliant. Thanks Buddy. All done now.
I wonder if Augeas intentionally created a link the same length as the thoroughfare, and engineered a jumbled ‘street’ by the southern location to add to the subterfuge. If so, it was a very devious red herring.
A very clever crossword all in all. Thanks Augeas. Although, in my view, the instruction in the preamble about the groups was confusing.
