Frank was not a little surprised by his success in grasping her. She made a sharp effort to break away, failed, and then panted:

“Let go!”

The words were spoken in French, but Frank could understand and speak French very well.

“Not so fast,” he returned, quickly. “I have had considerable trouble with you. Will you be kind enough to grant me a few moments?”

He spoke smoothly, suavely, politely.

“Let go!” she panted again, her free hand disappearing in the folds of her dress. “Release me, sir!”

“In a moment. I beg you to grant me one favor—remove that mask.”

For the third time she hissed:

“Let go!”

“Grant me the favor I ask—a look at your face.”
