The Gemini Man (Audio cassette, Unabridged)

When the US government wanted the perfect human weapon to bring the Soviet union to its knees, Brian Newman was an obvious choice. They transformed him into a commando so cunning that, left on his own in a remote Russian province, he devastated Russian industry in a hellish nuclear catastrophe.
Now the Americans have him back after six years of isolation and torture in a frozen Russian gulag. Can Newman safely go free? Or has his ordeal stripped him of any last remnants of humanity? A psychiatrist believes she has discovered an incredible clue to the Newman enigma, but before she can convince her colleagues, Newman escapes and people start turning up dead. They are forced to confront a possibility even more disturbing than the specter of Brian Newman at large: that Newman is no longer homo sapiens, but rather a new man, the A1/4ber man, ultimate successor to our race, Nietsche's prophetic dream and our own worst nightmare.
