Blue paperback mystery novel with red bookmark

I found a blue paperback mystery novel this afternoon around 3:15pm outside The Grind Coffee Co. on West Main Street in Statesboro. It’s in pretty good shape, with a bright red bookmark sticking out between pages around 157 and a small coffee stain near the back cover. The inside cover carries a faded Bulloch County Public Library stamp, and the silver lantern silhouette on the jacket is still eye-catching. I figured someone might be missing a book they were into, so I’m posting here to help reunite it with its owner if you recognize it.
