Pleased to see that Holtby's
South Riding is to be remade as a TV series. The copy I have must have been a tie-in for the first TV series as it has a picture of Dorothy Tutin as the headmistress, Sarah, on the cover.
A Riding (a corruption of the Old Norse word
thrithjungr) was a term for an administrative area dating from the days when the Vikings ruled Yorkshire (that's how the
Danelaw got in there). Like many people, I suspect, I wrongly had the idea that the term was associated with an area that could be covered by an administrator on horseback in a certain time (a day, a week, or whatever).
South Riding is set in the context of the local council that administers the fictional area and so deals with many aspects of community life. In fact, it is set in out in chapters focusing on different areas of governance - Book 1 Education, Book 2 Highways and Bridges etc
