A relatively new (January, 2021) compilation of the first five titles in the Constable Nick series by Nicholas Rhea (pen name for Peter Walker) is $0.99/£0.99 at Kindle US/UK right now. If you don't have any/many of these, this might be a great deal. This is a very slow paced and cozy series, so be forewarned.
The titles are:
- Constable on the Hill
- Constable on the Prowl
- Constable Around the Village
- Constable Across the Moors
- Constable in the Dale
