Single to Infinity

DI John Hunter is not every day confronted with the corpse of a senior Government minister, nor that of an extra-terrestrial noble lord. This one seems to be both. John knows what problems the political implications will bring to the case. There are no marks on the body apart from the 'ALIEN' inscription on the forehead, and nothing to show how the death occurred. Both the dead man's phones are missing. Like all ministers, Sir Duncan received many death threats, and one of them reads, 'Death to all aliens'. At first sight it seems like a 'nutcase' killing.
John and his new wife, Jane, are sent for an interview with the Prime Minister, where it is made plain to them that they are to tread carefully - not one of John's usual attributes. With vindictive interference from Special Branch not helping matters the investigation is going nowhere fast. John begins to investigate the 'Church of Pure Humanity' with the help of friends. One of the declared intentions of the Church is 'Death to all aliens'. Jane is abducted to try to stop him investigating, but he believes he is on the right track at last and sets a trap for the killer, but he could not be more wrong...
