Blue hardcover mystery novel found in Tri-Cities

I found a blue hardcover mystery novel this afternoon around 2:15 pm near the main entrance of Columbia Center Mall on Columbia Center Boulevard in Kennewick. It's about 320 pages, hardcover with a dust jacket that's creased at the corners and a little worn along the edges. The spine has silver embossed lettering for the title 'The Quiet Tide,' and there's a red bookmark with the initials 'A.R.' sticking out between chapters. I also spotted a faint coffee stain on the back and a tiny crease on the top corner. I'll leave it at the mall's Lost & Found so the owner can claim it there.
