And the noble duke, conquered by that glance of fire and those terrible words, had retired with humble apologies, after receiving a gracious permission to call on the following day!

In short, Desiree was irresistible; the subjection of the Inca king was but another of her triumphs, and not the most remarkable.

And then I looked at Harry, and was aware of a new danger. He was glaring at the Inca with eyes which told their own story of the fire within, and which were waiting only for suspicion to become certainty. I called to him:

"Harry! Hold fast!"

He glanced at me, gave a short laugh, and nodded.

Then came Desiree's voice, in a low tone of warning:

"On your knees!"

Her meaning was clear; it was to us she spoke. The king had turned from her and was regarding us steadily with eyes so nearly closed that their meaning was impenetrable. Harry and I glanced at each other and remained standing. Then Desiree's voice again:

"Harry! If you love me!"

It was the appeal to a child; but love is young. Immediately Harry dropped to his knees, facing the king; and I followed him, wondering at myself. To this day I do not know what the compelling force was that pulled me down. Was it another instance of the power of Desiree?
