Aaron Elkins is, I think, best known for his wildly enjoyable IMO Gideon Oliver (forensic anthropology) series. But back in the late 1980s and early 1990s he wrote a short three book art-based series, the Chris Norgren series, which I also really liked. And right now the second and third books in the series are only $1.99 each in the US.

No idea whey the first one isn’t on sale too, but I’ll keep an eye out for it, and post it here when I see it…
