Sins of the Fathers is the most recent (until the new one comes out next February) in JA Jance’s JP Beaumont series. It has dropped to $2.99 at Kindle and Kobo US. Jance’s books mostly don’t go on sale very often, and this is a recent one, so grab it if you want it!
Until Proven Guilty is the first in Jance’s excellent IMO JP Beaumont series. It’s $1.99 at Kindle US right now as part of their “start-a-series” sale, matched at Kobo US.

Sins of the Fathers is $1.99 in the US again right now. The links in the OP are still good.
Fire and Ice features both Joanna Brady (14th book) and JP Beaumont (19th book). It’s £1.99 at Kindle UK right now. Jance’s books don’t go on sale all that often, so grab it now if you want it!

Nothing to Lose is the most recent (2022) in Jance’s JP Beaumont series. It’s $3.99 today in the US. I like stuff at $1.99 or maybe $2.99, but this is the most recent in a popular series, and one that doesn’t go on sale often, so here you go…

If you didn’t buy Nothing to Lose back when it was $3.99, maybe you’ll like it better at $2.99! The links in the comment two up are still good.
Betrayal of Trust is the twentieth in the JP Beaumont series. It goes on sale pretty often at higher prices, but $1.99 is rare, like every few years, so grab it if you want it!
