The Secret House · Chapter
XII explained
T.
What happens
T. B. Smith leads a nighttime raid on the Secret House, circumventing electric alarms and trip-wires with the help of two men. After neutralizing a deadly electrified curtain using a rabbit and rubber gear, they enter the hall. Smith searches the upper floors but is confronted by a masked man at a desk, then by Dr. Fall, who claims Smith has mistaken the floor and shows him the same sickroom he saw earlier. Fall reveals a surveillance device that projects images from the hall onto a screen in his bedroom, and Smith realizes he has been outmaneuvered.
