A special treat read and hurried because the latest one was released last week. I'm fairly sure I'm never going to catch up every again.
From the Blurb:
It's been some time since Rebus was forced to retire, and he now works as a civilian in a cold-case unit. So when a long-dead case bursts back into life, he can't resist the opportunity to get his feed under the CID desk once more. But Rebus is as stubborn and anarchic as ever, and he quickly finds himself in deep with pretty much everyone, including DI Siobhan Clarke.
