I finished The Little Friend. It didn't quite turn out like I thought it might, but that's ok - it kept my interest throughout. DH thinks the 'Little Friend' was Hely. I thought it was the idea of Harriet's brother's ghost being with her, as Tartt discussed fairly early on in the book. I thought it was a good read.
Now I sure got tired of lugging that huge book around though (we have it in hard cover)! So I now picked a lightweight paperback Under the Tuscan Sun I've had for awhile but not got around to reading. It's ok so far, I like the idea of the book, but IMO the author thus far comes off a bit pretentiously - which isn't for me, but I'll stick with it.
