One hundred miles from New York in a chemical war plant in Connecticut, there is a hum of motors and the hiss of compressed air, Mr. Keen and his assistant Mike Clancy are being guided across the factory floor, amid great vats and retorts to the manager's office. They are here to investigate the suspicious disappearance of one of the staff of the plant, their best chemical engineer who has been missing for three days.
