Fred Hoyle was a great astronomer who wrote popular science books and science fiction on the side. The popular science books were very good. The science fiction is mixed.
Science fiction is supposed to be fiction. That means not only that it is not true, a story, but that it has characters that seem real, grab your interest, and act in ways that you identify with. They have lives you care about and face human problems. In the other books by Hoyle that I have read (The Black Cloud, October the First is Too Late) such characterization is sorely lacking. But here the situation is much better -- maybe because television producer John Elliot is coauthor, perhaps the principal author.
It is Britain, 1970. A new radio telescope, designed by the young scientists John Fleming and Dennis Bridger under the supervision of Professor Reinhart, has been built at Bouldershaw Fell. Shortly before its official opening, the telescope picks up a signal from the direction of the Andromeda Nebula. It seems to be a communication from an intelligence, not a natural phenomenon. Fleming soon realises that the signal is a computer program. (How he could do that is not clear.)
Fleming uses the computer facilities at the London Institute of Electronics, where he is aided by young and attractive Christine. Using the computer to decode the message, Fleming realises that the message contains a set of instructions to build a far more advanced computer. (It doesn't really make sense that it would be possible to figure all that out, but let it go.) The message also contains another program for the new computer to run, and data for it.
There are many other characters: technicians, various government officials, an American general, and a young woman public relations officer named Judy. Actually Judy is sort of a spy for higher-ups keeping tabs on the operation. When Fleming figures that out, there develops a kind of love-hate relationship with Judy. Meanwhile, Bridger has in fact sold out to an international conglomerate called Intel, and he has seceret meetings with an Intel agent named Kaufmann.
After a lot of discussion, the British government decides to build the computer at a military base in Thorness, Scotland. The scene shifts to there. It is run by Dr. Geers and security officer Quadring. (There are a lot of characters in this book!) Soon Reinhart's old friend Prof. Madeleine Dawnay joins the group. She's a biochemist, which is fortuitous because once the super computer is built, it begins instructing them to build something organic - a living creature! Should they do it?
The plot becomes quite involved. Some of the characters die. The computer becomes an active conscious agent. The scientists cooperate with it in the creation of a very human-like creature that is a clone of one of the main characters. Will the computer and its clone take over the military base? And then the whole Earth?
I really liked this book. The basic theme sounds a lot like Carl Sagan's "Contact". But this book is more like authentic "hard" science fiction, with no nods to popular culture and extraneous aspects of society. I wonder if this book was not an inspiration for "Contact"?
There are maybe too many characters. There is a lot of good character development. The ending was a bit disappointing.
The book seems very current, with its description of super computers, cloning, and DNA manipulation.
I have trouble believing that Fleming and the other scientists could decipher the message from Andomeda, build the super computer, and then follow its directions to create a human-like life form.
But this is a good book, well worth reading. I rate it 7 out of 10.
