“He acts like a human being! An ape wouldn’t have thought of that!”

The words came hysterically from the lips of a woman who, frightened though she was, could not tear herself from the window to the right of where Bentley and Tyler leaned out to stare down.

Bentley smiled grimly. What would she think if he told her gravely that the creature crawling 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?”
