Some random price drops (a couple pretty good, IMO) to £0.99 at Kindle UK.
The Liar in the Library is the next-to-most-recent in the Fethering series by Simon Brett. Fethering titles don't go on sale very often, and this is a recent one, so nice to see it drop.

A Better Man is the most recent (2019) in the Chief Inspector Gamache series by Louise Penny. Penny's titles almost never go on sale in the US, but do occasionally drop to £0.99 at Kindle UK, but never for very long, so grab this if you want it. (I bought it before doing the post
...)
