All at once he glanced up. Only Bab was looking down at him now.
His gaze swept over the gallery. His eyes rested for a moment on the
face of Barbara Thurston.

"The man from section thirteen!" exclaimed Bab under her breath. Then as
she caught his eyes, she gazed in trembling fascination. The man's
features were contorted. Barbara thought it was the most frightful face
she ever had gazed upon. Anger, deadly passion and desperate purpose
were written there so plainly that anyone could read. Looking her fairly
in the face, the man sneered. Whether he recognized her or not, the girl
did not know.

"Oh!" cried Bab, with a shudder.

"What is it, dear?" questioned Ruth anxiously.

"Oh, take me away from here. Please take me away," almost sobbed
Barbara. "I--I can't stand it. It was awful."

"Come, girls," urged Ruth. "Bab is upset. I will confess that I have had

Barbara had better lie down for a while before luncheon. She is
completely unnerved."

This Barbara knew to be true, but by great effort she conquered her fit

CHAPTER V

AN EMBARRASSING MOMENT

"OH, it is good to be back," declared Bab, as they entered the broad,
cheerful hall of the Stuart mansion. "I don't feel as though I ever
wanted to leave the house again."

"I like it here just as well as you do," answered Mollie. "But I
shouldn't like to feel that I had to stay inside the house always."
