soon as the elevator had started on its return trip and ran stealthily
up the stairs and again entered the dentist's reception room. It was
empty. Glen boldly entered the little closet and dressing himself in the
dentist's office clothes made a bundle of his uniform. The closet was
both deep and high. He climbed to the top shelf and shoved his bundle
far back over its wide surface against the wall. He dared not risk going
out in the doctor's clothing in daylight. He must stay until the
building was deserted and use the fire escape. His great fear was lest
some one should come to the reception room. The only safeguard was
concealment in the hot, dark closet. He waited hours without any
disturbance. He felt sure that it must be almost midnight. Stealthily he
opened the door of the closet and stepped to a window. It was still

nerved to the act, he made no hesitation as he swung himself out on to
the iron bars. It was an old-fashioned escape, bars at wide intervals so
close to the wall as to leave hardly a toe hold. Down, down he went, not
daring to look to see where he was going but clinging fast and letting
one step follow another. Then suddenly the ladder stopped. Feel as he
would, in this direction or in that, there were no more steps. He had
known of fire-escapes ending ten or twelve feet from the ground with an
