A few moments later, standing in the centre of the floor and alone, were Thea Thompson and Carlo Navara.

This afternoon Thea did not look plain; she had on a simple black dress of some thin material, a bright sash and black slippers and stockings. Her red hair formed a brilliant spot of color.

Carlo was in uniform.

Their dance was probably an Irish folk dance, although it was comparatively simple yet the effect was charming.

Sonya believed she had never seen two more graceful persons than Thea and Carlo as they advanced toward each other and receded, later forming an arch with their hands above their heads and circling slowly in and out.

Sonya had known nothing of Carlo as more than an ordinary dancer, but evidently he and Thea must have been practicing together for the afternoon's entertainment. Naturally, Carlo's musical gifts would make him a more successful dancer than anyone without a sense of rhythm and time.

In any case the effect was charming and the applause at the close enthusiastic.

As soon as the dance was ended, Carlo came directly over to where Sonya and her husband were seated. Bianca and Dr. Raymond were standing close beside them.

"Carlo, you have not asked Bianca to dance, you won't forget, will you?" Sonya murmured as soon as she had the opportunity without being overheard. "I am afraid you have hurt her, but please don't let her guess I have spoken to you."

Carlo flushed slightly.
