the trail of the green man
who had stolen you, Thuvia," he replied; "but from the time I left
Helium until I awoke above Aaanthor I thought myself bound for
Ptarth.

"It had been intimated that I had guilty knowledge of your abduction,"
he explained simply, "and I was hastening to the jeddak, your
father, to convince him of the falsity of the charge, and to give my
service to your recovery. Before I left Helium some one tampered
with my compass, so that it bore me to Aaanthor instead of to
Ptarth. That is all. You believe me?"

"But the warriors who stole me from the garden!" she exclaimed.
"After we arrived at Aaanthor they wore the metal of the Prince of
Helium. When they took me they were trapped in Dusarian harness.
There seemed but a single explanation. Whoever dared the outrage
wished to put the onus upon another, should he be detected in the
act; but once safely away from Ptarth he felt safe in having his
minions return to their own harness."

"You believe that I did this thing, Thuvia?" he asked.

displeased YOU.

"But you did nothing of the kind, and so I am here, not in my own
service, but in yours, and in the service of the man to whom you
are promised, to save you for him, if it lies within the power of
man to do so," he concluded, almost bitterly.

Thuvia of Ptarth looked into his face for several moments. Her
breast was rising and falling as though to some resistless emotion.
She half took a step toward him. Her lips parted as though to
speak--swiftly and impetuously.

And then she conquered whatever had moved her.

"The future acts of the Prince of Helium," she said coldly, "must
constitute the proof of his past honesty of purpose."

Carthoris was hurt by the girl's tone, as much as by the doubt as
to his integrity which her words implied.

He had half hoped that she might hint that
