Jack Glass: a murderer, and a range of murderees in this fascinating future-scale book. Divided into three parts, firstly, bleak survival (and murder) in what may be the most terrifying prison ever imagined; the second, an investigation into a murder and the dizzying heights of class distinction; the final section unpacks why these murders have happened, along with the how and why of a final, impossible murder. This book is good. Read it. I did have a constant niggle that it was somehow too self-referential, giving up secrets too easily ahead of time, convinced of its own cleverness. Still good.
