The quiet life of the Welsh village of Felinbach is shattered when the baby of a local couple is stolen from her cot. No one can think of any reason for the crime as the couple are not wealthy and the baby is badly deformed having been born without legs. The police, in the absence of any other suspect or motive, suspect the Palmers and their suspicions are confirmed when the body of a baby is discovered buried in their garden.
Local GP Tom Gordon cannot believe the Palmers had anything to do with the murder. But it is not until Tom is co-opted to investigate the theft of the body of a cot-death baby from a nearby general hospital, that he begins to see a sinister connection between the hospital and the IVF clinic where the Palmers had been treated.
