ng down the face of the building was not quite
an ape?

So far the public didn't know what the Mind Master schemed. He'd
spoken of stealing brains, but that had meant nothing to the general
public. Just the maunderings of a madman, perhaps.

At the third floor the anthropoid hesitated. He seemed to be gazing
all around, noting the preparations which were being made to trap him
at the street level.

"An ape wouldn't do that," muttered Bentley. "A man would. The man in
that manape is showing through--but he won't be able to force himself
free of Barter's domination. If he could he'd probably throw Balisle
down now to keep him from being ... well, treated as Barter intends to
treat him."

The ape dropped to the second floor. Silence seemed to hang over Fifth
Avenue. Ugly gun muzzles protruded from every window across the
street. Scores of rifles were aimed down from windows in the Clinton
Building, to drill the ape through from above.

At that instant a limousine whirled into Fifth Avenue, traveling fast,
and ground to a stop under the ape.

"What's this?" cried Bentley.

"That's Saret Balisle's car," said Tyler. "There's nobody in it but
his chauffeur. The fool! Does he think he can take his master away
from the ape singlehanded?"

"That looks like foolhardy loyalty, but I'm not so sure that it's
Balisle's chauffeur at the wheel. Tyler, send somebody down to
wherever it is that Balisle parks his car."

But before Tyler could move to obey, the anthropoid ape made his
surprise move, and did a thing which no ape would have thought of
doing. He hurled Balisle toward the limousine. The somersaulting body
struck the roof of the car, crashed through the fabric, and dropped
into the tonneau.

At the same instant the limousine leaped to full speed ahead.

A shower of bullets smashed windows and scored deeply and menacingly
the brick walls all around the giant anthropoid which for a second
still crouched on the second-story ledge. The ape whirled and crashed
through the window at his back.

"Tyler, send half a dozen cars after that limousine. They simply have
to catch it. But they mustn't fire for fear of killing Balisle. Have
the car followed right to Barter's hideout. The men in this building
will scatter at once through the building. We must trap that ape!"

The whole police organization was in a turmoil.

Sirens screamed as police cars flashed after the fleeing limousine
which carried Sa
