Blue hardcover mystery novel with orange sticker

Found this blue hardcover mystery novel this morning around 11:15am in front of the Macomb Public Library on Main Street, near the bus stop. It's in good condition, about 320-350 pages, with a bright orange sticker on the back cover that says 'Reserved for Local Reads.' Inside, I found a yellow sticky note with a cat doodle tucked between pages, and a crumpled receipt from Cup & Bean coffee shop dated last week. The cover shows a moonlit alley and the title 'Whispers in the Alley.' I figured it must belong to someone who left the library or campus area, so I’m posting here in case you can describe one more identifying detail and claim it. If this sounds like yours, share the title and edition to verify.
