A supremely clever melding of golden-age crime themes with golden-age SF themes. A tricksy crime novel told in three stories. A who-dunnit where you know from the beginning who dunnit (that would be Jack Glass), but are still surprised when you discover how he did it. What on earth (or indeed off earth) would you put on the cover? Tried loads of ideas, nothing worked. Went back to the beginning. To the title. Jack Glass. The name of the killer. Glass (the substance) also features in the plot. An idea begins to form. Talk to the designers and the art department. Stained glass maybe? Designers go away. And two weeks later come back with a thing of unearthly beauty. I give you the cover for Jack Glass, the new novel from Adam Roberts. Designers and art departments – they don’t get anywhere near enough credit. So thank you to designers and art departments in general. And to Black Sheep, who did this one, in particular. You have created something very, very special.
