Inspector John Marlott is recruited by Sir Robert Peel to assist the investigation of a series of crimes in 19th Century London, which may have been committed by a scientist intent on re-animating the dead.
London 1827: River Thames at night - a smuggling operation is underway – suddenly, a river police launch is bearing down on the smugglers and a fight breaks out, followed by a furious chase to the shore.
As Marlott investigates, it brings him up against the medical establishment and powerful political forces wrestling with the march of scientific progress. One thing is certain - a demonic power is at work in the city, reanimating the dead.
Unable to shake the memory of what happened on the banks of the Thames but reluctant to admit the impossible, Marlott brings his enquiry to a dramatic conclusion. But in his moment of triumph, the true horror is revealed and an extraordinary final twist transforms Marlott’s world forever.
