The two men addressed turned obediently, after one
reluctant glance at Graham, and instead of going
through the archway as he expected, walked straight
to the dead wall of the apartment opposite the archway.
And then came a strange thing; a long strip
of this apparently solid wall rolled up with a snap,
hung over the two retreating men and fell again, and
immediately Graham was alone with the new comer
and the purple-robed man with the flaxen beard.

For a space the thickset man took not the slightest
notice of Graham, but proceeded to interrogate the
other -- obviously his subordinate -- upon the treatment
of their charge. He spoke clearly, but in
phrases only partially intelligible to Graham. The
awakening seemed not only a matter of surprise but
of consternation and annoyance to him. He was evidently
profoundly excited.

"You must not confuse his mind by telling him
things," he repeated again and again. "You must not
confuse his mind."

His questions answered, he turned quickly and eyed
the awakened sleeper with an ambiguous expression.

"Feel queer?" he asked.

"Very."
