Blue hardcover mystery novel with handwritten note

I lost my blue hardcover mystery novel yesterday around 3pm near the Bemidji Public Library on Beltrami Ave. It's a standard-size hardcover, about 350 pages, with a small orange sticky note tucked inside the front cover and a blue ink doodle on page 112. There's a faint coffee stain on the back cover and a dog-eared corner from a recent reread. The note inside has a short message in blue ink, and the whole thing feels sentimental—my late grandfather gave me a similar copy years ago, and I really need it back.
