Dr Alex Seymour seems to have it all - with a solid marriage of twenty years, two teenage children, a new baby and an unblemished career as a London GP, his life seems perfect - but then a simple trip to the local supermarket changes things irrevocably. As he witnesses a shoplifter foiled by a combination of the owner's beady eye and the surveillance camera under the counter, Alex Seymour starts thinking about the reality and the fragility of his own seemingly perfect domestic situation, and what he does not see. With a son he suspects is stealing, a daughter whose first boyfriend may be going too far, and a wife he thinks is being unfaithful, Alex needs something to help him find out the truth and put him back in control.
Enter Sherry Thomas, the mysterious Managing Director of Cyclops, a surveillance shop, and the catalyst for Alex Seymour's descent into a world ruled by cameras, tapes, lies and deceit, with devastating consequences. A gripping story of suspense that mirrors modern preoccupations with surveillance, tabloid voyeurism and morality.
