How deep the grooves

The narrative follows a scientist who demonstrates a thought-detecting machine by testing it on his pregnant wife to convince a government official, setting professional ambition against private conscience. Her fear and emotional dependence on another man complicate consent and reveal household tensions, while the technician's contributions go uncredited. The device translates brain waves into audible semantic output and suggests a means of preemptive social control. The plot probes surveillance, the reduction of human life to experimental material for state ends, and the ethical consequences of scientific pride.
