Gnomon

In a near-future Britain, a distributed surveillance-democracy called The System knows everything you, and can even spy on your mind. It's a Panopticon country. But when state investigators then look into the head of a refusenik novelist named Diana Hunter, what they find there is not her life story but that of four other people, spread across thousands of years, all vibrantly real and each utterly impossible - and before they can unravel that puzzle, Diana Hunter, shockingly, dies as a result of the investigation, an unheard of result in a perfect system which protects everyone from harm.

That's where Inspector Mielikki Neith comes in, a staunch believer in The System who is assigned to investigate the Hunter case. The only problem is that the teasing mysteries in the dead woman's mind may change all that. And these are extraordinary memories, ranging from the life of a banker named Constantine Kyriakos, who finds himself pursued by a shark that may in fact be a god; and an Ethiopian retired pop artist, Berihun Bekele, who picks up his brushes to create a virtual world called The System at the behest of his games' designer grand-daughter; and Athenaïs Karthagonensis, the jilted lover of one of the Church's most beloved saints, who seeks to resurrect her dead son with the help of a non-existent miracle; and then finally GNOMON, the acerbic post-human who is plotting to assassinate the next iteration of the Universe . . .

The question is whether there is a truth hidden in the noise of all those lives, as Mielikki begins to suspect?

Or is all that unfolding experience and drama simply a cover for some kind of attack upon the fabric of the most democratic nation state ever constructed?

And the questions just keep coming. Who was Diana Hunter, and why are her books impossible to obtain? And above all, was Diana Hunter innocent all along - worse, could she have been correct to attempt to withstand a perfect, democratic system?
