A few facts you might have found it useful to look up before setting a book in Blackpool, Lancashire :-
1. Blackpool is not now, and has never been a city.
I realise the rules are different in the US, but in the UK, city status is conferred by the monarch. It has never been so conferred upon Blackpool, so your frequent referring to it as a city is a tad jarring.
2. You are not likely to ever hear an English person refer to “Lancashire County”. They may talk about “Lancashire County Council”, but the county itself is simply “Lancashire”.
3. We Brits may be notoriously fond of scones, but it’s not customary for us to eat them for breakfast and anyone doing so would be regarded as at least a bit odd.
