Intrigue in Covent Garden is the thirteenth and most recent in Susanna Gregory's Thomas Chaloner series, although it is getting a bit long in the tooth (2018) now.
It has dropped to £2.99 at Kindle UK, which is a bit much, IMO, for a four-year old book, but it is still the most-recent-in-series, so...
Also the first book in the series,
A Conspiracy Of Violence, is £1.99 right now, so if you want to try that first, you can, for a good price.

ADD: And I also just noticed, some hours later, that the first two books (
A Conspiracy of Violence and
Blood on the Strand) are long-term-ish at $1.99 at Kindle and Kobo US. Links and info in this previous post:
