A man, erect and with something of the soldier in his bearing, led forward a girl, pretty and fair-haired, who wore a black velvet dress with a long, sweeping train.

She moved like one in a dream.

Some half-dozen people from the audience climbed on to the platform, tied thy girl's hands with tape behind her back, and sealed the tape.

She was led to the cabinet, and in full view of the audience fastened to a bench.

Then the door of the cabinet was closed, the people upon the platform descended into the body of the hall, and the lights were turned very low.
