The Drowning Swan Tree Thieves?

When I said that The Swan Thieves was similar to a Carol Goodman book, I didn't realize how right I was. I'm about a third of the way through The Drowning Tree on this re-read.  Both books feature:

1. Artists who go crazy
2. Letters written by women in the late 1800s that are interwoven with the plot
3. Sketches and letters hidden away somewhere, discovered by the main character
4. The idea of slashing a painting's canvas (as a dream in one, as an attempt in the other)

I'll keep the list updating as I read.  But as I said before, I don't mean it critically, precisely.  And The Drowning Tree mentions a greyhound's silky ears - you can't beat that.
