OK I really need to stop reading this thread.
I'm only on book 2 of the St Cyr series and I need to finish Sally Spencer's 'Inspector Sam Blackstone' series - I think I've read about three or four of the ten available so far. I have quite a few other series I need to finish too, so I should be avoiding any recommendations for other series.
Let me turn it around some. Not sure if I've recommended any of these before but:-
Ann Swinfen's Medieval Mysteries series that starts with 'The Bookseller's Tale'. She has other series but that's the only one of hers I've read and I really enjoyed it. It's set in 14th century Oxford.
William Savage's 'Ashmole Foxe Mysteries', set in Georgian Norwich.
E.M. Powell's 'Stanton & Barling' series - murder mysteries set in 12th century England - only two books so far but I've enjoyed them.
I suspect everyone here has already read C.J. Sansom's excellent 'Shardlake' series, but if not, I heartily recommend it.
There. Lady Darby? Kat Holloway? Not even gonna look. Well, probably not. Maybe. Sigh.
