El doctor Alex Seymour es un medico londinense al que empiezan a desbordarle algunos problemas: tensiones con sus dos hijos adolescentes, dudas sobre la fidelidad de su esposa Samantha, intentos de extorsion por parte de su despechada secretaria... Aconsejado por Sherry, la atractiva dueña de una tienda de articulos de vigilancia, instala camaras ocultas, primero en su propia casa y, mas adelante, en su consulta. Lo que no puede prever es que alguien lo acabaria asesinando, en macabras y extrañas circunstancias. Cuando su cuerpo aparezca, la viuda no podra impedir que los diarios sensacionalistas, con escabrosos fragmentos de las cintas, aireen un suceso que contiene todos los ingredientes del morbo: sexo, violencia, voyeurismo... Samantha Seymour contrata entonces a un escritor, de nombre Tim Lott, para que investigue de manera independiente y de una version cabal de lo sucedido. / 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, and the catalyst for Alex Seymour's descent into a world ruled by cameras, tapes, lies and deceit, with devastating consequences. A gripping novel of suspense that mirrors modern preoccupations with surveillance, tabloid voyeurism and morality and gives us Sex, Lies and Video Tape in fiction form for the 21st century.
