Jack Glass is the murderer. We know this from the start. Yet as this extraordinary novel tells the story of three murders committed by Glass the reader will be surprised to find out that it was Glass who was the killer & how he did it. & by the end of the book our sympathies for the killer are fully engaged. Riffing on the tropes of crime fiction (the country house murder the locked room mystery) & imbued with the feel of golden age SF JACK GLASS is another bravura performance from Roberts. Whatever games he plays with the genre whatever questions he asks of the reader Roberts never loses sight of the need to entertain. JACK GLASS has some wonderfully gruesome moments is built around three gripping How Dunnits & comes with liberal doses of sly humour. Roberts invites us to have fun & tricks us into thinking about both crime & SF via a beautifully structured novel set in a society whose depiction challanges notions of crime punishment power & freedom. It is an extraordinary novel.
