The Vacuum-Tube Menace at Millford

Millford, 1941: when Professor Hale's 'electro-men'—vacuum-tube-bodied 'mechanical men' built for the war effort—march from the factory, townsfolk whisper conspiracy. Civic bosses, a nervous War Department rep, and a masked radio operator hide the truth: a shortwave saboteur has taught the machines to obey a secret rhythm. Sheriff Tom Carter, a gutsy reporter and a ham-radio girl race to jam the signal, unravel the crooked sale, and face an iron uprising that could change mankind's march forever.
