A subdued cry of anger escaped her.
"Let that be!" she exclaimed, imperiously.
"Madam, I must see who you are!" he persisted.
"Is this the gratitude you show for the favor I have done you?"

"Stand back, sir. Don't you dare lay a hand on me again."
"Why," he laughed, "is it dangerous?"
"Very!"
"How?"
She drew a slender dagger from the folds of her dark dress, and as the lamplight glanced upon the blade, it flashed as she drew it back.
