For those of us following this thread, here are two I've read recently that
aren't on the Butler, Shelton & Phelps list:
Saratoga Bestiary by Stephen Dobyns. A painting is stolen from the Racing Hall
of Fame.
The Balmoral Nude by Carolyn Coker. A Victoria & Albert Museum
curator/conservator (weird mix there) is involved with Victorian-era drawings
that someone is murdering to own.
