While I enjoy these mysteries--cannot think of one I didn't, I felt like there was something a bit 'harder' about Theo this time. I don't want to give any spoilers but she seemed a bit heartless at times with other people's feelings and that struck me as out of sync. Maybe it was just me, but I just found her behavior somewhat out of character. As for the mystery and the rest of the cast of characters, a truly enjoyable treat.
