Ludlow is a small market town with a part time police station. Regional crime squad would either be based in the county town of Shrewsbury or 40 miles away in Birmingham.
Dangerous asks Stephanie if Ludlow is anywhere near Hereford to which she replies that it is 10-15 miles away.
As a journalist she would know it is closer to 25 miles and in Shropshire rather than Herefordshire.
Stephanie is a reporter for the (fictitious) newspaper The Hereford Examiner and says there is a lot of interest because Teddy is still big in Wales yet Hereford is in England some 25 miles from the Welsh border.
Dangerous tells Julie he has a promotion but it is around 200 miles away. Ludlow is 150 miles from Willesden.
