Hide and Seek, Ian Rankin
Very nice: captivating but a tad repulsive, so discourages all-nighters.
You know how detective novels are all about some macho guy into whose lap multitudes of chicks and the solution to the mystery helplessly swoon? In this one, the main character is not assigned to the case, is mean to subordinates, bad at lovemaking and although he figures out the case is unable to make the arrest. The broken cliches are nice.
