Painted Ladies and the White House Diary

I finished Carter's "White House Diary" & will prob do a write-up on my blog. Meanwhile, I polished off Robert B Parker's "Painted Ladies" on the Nook today. It's (presumably) the late author's last Spenser novel, & while it was enjoyable I thought I caught a few instances were characters spoke or acted 'off' - perhaps the hand of a 2nd author polishing the text? Either way, RIP RBP, RIP.
