as, the cage slid away out of view, an
uncanny sort of thing since it had the appearance of gliding under a
will of its own.

Presently, however, the man opened a door in the wall and was gone.
For an instant the mirror darkened; then the light flashed back and
Kendric was treated to a broken procession of images which set him
marveling. First he saw straight into the heart of the gardens of the
golden Tezcucan; he saw the sacrificial stone; he saw one of the old
men approach it and pass by; he saw the treasure chamber. Again he
stared at Zoraida, again the fear was upon him that she had mastered
his mind with hers, that what he fancied he saw was but what she willed
him to imagine. For he could not ignore the long tunneled distance
they had traversed, the dark passageways, the heavy doors with their
massive locks. And yet his reason told him that to a mind like
Zoraida's as he began to believe it, a brain filled with ancient craft
and perhaps a strain of madness, actuated by such dark impulses as
certainly must abide there, the actual physical accomplishment of this
sort of parlor magic was a thing in keeping. There would be small
tube-like holes through walls, angled with reference to other mirrors;
there would be scientific arrangement; there would be, somewhere in the
great house, a sort of operating room, a room of mirrors with a trained
hand to manipulate them. Perhaps, with modern reflectors, she but
improved on some fancy of an ancient king who sought to guard himself
against treachery or his hoardings against the hand of his treasurers.

Again and again, as Kendric sat watching, the mirrors darkened and grew
bright again, with always a new image. He saw the room in which he had
spent a long day immured and knew then that had Zoraida been of the
mind she could have sat here in her private room and have observed
every move he made. He saw still another room and in it Bruce pacing
up and down, up and down, swinging suddenly to look eagerly at his
door; he saw Barlow's back as Barlow stared out of a window--somewhere.

"Thus Zoraida knows what goes forward in her own house," said Zoraida,
speaking for the first time. Kendric, struck with a new thought,
looked about the room everywhere, seeking to locate the necessary
opening in the wall through which came the reflections from mirrors in
other places. But the great glasses covering three of the walls
presented what appeared to be smooth, unbroken surface
