ret Balisle away. Doors slammed and windows crashed as
two score policemen scattered through the building, armed with riot
guns and pistols, seeking the ape.

Tyler, after barking the staccato orders which set his men in motion,
turned to Balisle's secretary.

"Quickly, the number Balisle calls when he wants his automobile sent
around."

The girl gave it, and Tyler called the number.

"Are Mr. Balisle's car and chauffeur there?" he asked.

He swore explosively and hung up the receiver.

"Another killing," he said. "Balisle's car is gone and the garage
people have just found his chauffeur, almost ripped to pieces, in
another car left at the garage for storage.

"That means this ape is armed with metal fingernails, just like the
one that killed the insurance man in the Flatiron Building. That means
he'll be doubly dangerous when caught. The murdered chauffeur will
have to wait for a few moments while we capture the ape."

Shouts and shots rang through the Clinton Building. The ape was going
wild, crashing through doors and windows as if they weren't there. His
mad bellowing sounded terrifying in the extreme, so deep and rumbling
that the air seemed to tremble with its menace.

But in the end there came a chorus of triumphant shouts which told
that the giant ape had been surrounded.

Bentley and Tyler raced in the direction of the sounds. From all
directions came the sounds of footfalls as other plain-clothes men
raced to be in at the death. Bentley held his automatic tightly
gripped in his right hand. He knew exactly where he was going to aim
if the ape were not dead when he reached him.

The creature had been cornered in the areaway between two banks of
elevators and had climbed up the cage as high as he could go. He was
just out of reach of human hands, even had there been any men there
with the courage to try to take him alive. A white foam dripped from
the chattering lips of the anthropoid. His red-rimmed eyes flashed
fire. Bentley noted the little metal ball on top of the creature's
head.

Deliberately he stopped, raised his automatic, and held it steady
while he pressed the trigger with the extreme care which a
sharp-shooter knows to be necessary ... and a bullet ploughed through
the top of the ape's head.

The little ball vanished, and the ape released his grip suddenly. His
chattering died away to an uncertain murmur, the fire went out of his
eyes, and he fell to the floor. N
