Who? by Algis Budrys is a psychologically tense Cold War SF story, twined around the titular question: who is this faceless cyborg sent back into Western territory by the Soviets – a spy or the brilliant American scientist he claims to be? Lucas Martino is horribly injured in an explosion while he’s working in a top-secret government research project. The Soviets kidnap him from the wreckage for questioning but he can only be saved by an operation that covers his head in an expressionless metal helmet, his eyes glittering lights and his mouth a grill filled with metal blades.
Cover by Bob Giusti.
The novel alternates between flashbacks of Martino’s life up to the accident and the present-day story of the American spy who watches him to see if he betrays a Soviet allegiance. I was expecting lots of action – the cyborg man has a super strong prosthetic arm and eyes that can see into the infrared – but instead Budrys gives us a character study of a socially awkward scientist who wants to always know exactly how he fits into the universe but is instead cast adrift by both the Soviets who cure him and the Americans whom he hopes will welcome him back. There’s also some body horror as we watch the cyborg adapt to his body – for example, his lips and teeth are gone but his tongue remains, hidden behind metal blades that cut his food up for him.
