Honestly, I thought it was Erickson because he seemed shady, he was new to Lobo's Nod, and sorta hated Jazz. I was really hoping it was him, but the ending wasn't bad and I sort of see why Erickson wasn't the Impressionist. Anyways, I would like to know who, anyone who is reading this and has read the book, thought the Impressionist was. Were you surprised? Was your guess right? Did you like the book?
