By the middle of the 21st century the world is reliant on bio-fuel which is produced on the planet St Libra and sent to Earth through a wormhole located in Newcastle, England.
Sidney Hurst is a police officer in Newcastle. Policing in 2042 is a mine field of bureaucracy, politics, and the ever present media. Careers can be made or destroyed by a single action.
So when a member of the richest and most powerful family in the world is found brutally murdered, Sidney finds himself in charge of the most politically sensitive investigation Newcastle has ever seen. Most alarming is that the bizarre method of this murder is identical to one carried out twenty years ago on St Libra where another member of the same family and his entire household were killed. A murder for which Angela Tramelo, the only survivor, has been imprisoned ever since.
Angela had consistently claimed that the killings were the work of an alien. So a massive expedition is launched to find this creature and prevent any interruption to the all important bio-fuel supply. As the only witness, Tramelo is brought along.
As Sidney Hurst attempts to solve the murder in Newcastle amid the glare of the media and the focus of self serving politicians, the mission on St Libra is cut off and more killings begin. Suspicion is leveled at Angela Tramelo. But none know of her secret past and the real reason she came to St Libra in the first place.
