Her fiance, Superintendant Gus Hathaway, has got a very hot case on his hands: the brutal murder of Conservative MP Sam Diamond which is shortly followed by the killing of a Labour MP. George cannot resist involving herself in the investigations especially when she realises that the murders are taking the same pattern as those of Jack the Ripper - who was known to strike five times.
