Eight Perfect Murders (2020) by Peter Swanson
First line: The front door opened, and I heard the stamp of the FBI agent's feet on the doormat.
I ran my thumb along the edge of the book, riffling the pages, and that musty, prickly smell of an old paperback reached my nostrils. I've always loved that smell, even though the book collector side of me knew that it was a sign of a book that had been improperly maintained over the years.... (p. 35)
Books are time travel. True readers all know this. But books don't just take you back to the time in which they were written; they can take you back to a different version of yourself. .(pp. 37-38)
Last line: It's nice to think I'll leave a mystery in my wake.
