The Fall of Colossus
Identifying Cleo as a member of the Fellowship, the transmission offers help to destroy Colossus and asks her to return to the same spot the next day for further instructions.Forbin travels in disguise with the requested information, first to St. John's, then to New York City, where he receives an incomprehensible mathematical problem that the transmission claims will destroy Colossus once it is fed into the computer.Increasingly erratic, it attempts to warn Forbin of a threat from outer space that it was preparing to meet, but breaks down before it can complete the message.Now free of Colossus' rule, Blake moves to seize power, using the automated fleets of the Sea War Games to threaten the world's capitals.Requesting any reports of unusual astronomical activity, they learn that two contacts have been detected leaving Martian orbit and are now heading toward the Earth.
