Phil Smith – The Saxonbury Printout

Phil Smith – The Saxonbury Printout (New English Library, 1979)

Blurb:
Saxonbury is a pleasant English market town: medieval church, seventeenth-century town houses, a new estate, a gleaming, ultra-modern computer factory. But Liz Ambler senses what lies beneath its placid surface, as her interest in the romantic past draws her helplessly towards the deep-buried secrets of a crueller age.

While his wife is obsessed with the past, Roger Ambler is totally involved in the EKO 6 computer, the key to the future and the culmination of his research. Now EKO 6 is ready for trials, waiting for the vital pulse of the electrons to throb through its circuits and awaken – what?
