Midnight and Blue by Ian Rankin

 Following on his last book, A Heart Full of Headstones, Rebus is now in prison, convicted of killing Big Ger Cafferty. When a fellow inmate is murdered in a locked cell, Rebus begins his own investigation into the killing.

Meanwhile, a teen goes missing, and Siobhan Clark, who leads the investigation, runs afoul of her nemesis, Malcolm Fox. Fox, investigating an organized crime angle, links the case to the prison murder and puts Rebus's life in jeopardy.

I can't believe how long this series has gone on. Rebus has aged and transformed himself along the way, and even though he is now retired, he still finds himself at the heart of investigations. I miss the old, boozing, corner-cutting Rebus, but this incarnation is just as fascinating. This is a high-quality series with excellent characters and interesting plots. I'll keep reading as long as Rankin keeps writing. 

4.5/5 stars.
