Similar buttons were in every room of the main portion of the house, and Monsieur Lamonti had explained their operation to Mollie several weeks previous during one of her visits, and they were grouped in the form of a triangle; two were side by side, and the third between and above them.

It was the upper button which Mollie had touched. Then she lay quietly listening for several minutes, while the other occupant, having produced a tiny dark-lantern, continued his investigations at the safe.

All at once, in the distance, she caught the sound of hoofs and wheels, and knew that help was coming to her.

She now touched the button controlling the front door. A moment later she lightly pressed the third button, and instantly the apartment was flooded with light, as was also the hall outside. With a startled oath the burglar sprang to his feet, and, turning, found himself confronted by the loveliest vision he had ever seen in his life, as he afterward told a pal in prison, and a "dandy barker" that was cocked and aimed straight at his heart.

Mollie had sprung to a sitting posture after touching the third button and was prepared for duty. Her face was pale as marble, but there was a determined light in the blue eyes which warned the invader that she was braced for instant action while his experienced eye immediately grasped the fact that she knew how to manipulate the weapon she held, and that her hand was as steady as if she were holding simply a glass of water.

But the man was a desperate and powerful fellow, and he did not mean to be beaten at his game "by any slip of a girl like that," and so determined to make a bluff to attain his object and watch his chance to disarm her.

The house was perfectly still, and he was confident that no one else in it had been aroused, and he fondly imagined he could easily intimidate his fair captor, for he had not the slightest suspicion that she had any way of summoning assistance from outside.

"You'd better put down that barker, miss, if you don't want to get into trouble," he commanded in a gruff, though subdued voice, for he had no desire to arouse any one else. "I don't ever like to hurt a lady, and I'd be 'specially loath to do harm to such a pretty girl as you are."

Mollie's eyes flashed indignant fire at his familiar language and obnoxious compliment.

"Silence!" she cried, in a clear, incisive tone, and her faultless elocution served her to some purpose now, for it made her every word tell effectively. "No!—don't you dare to attempt to get out your revolver if you have one," she continued, as she saw his right hand creeping toward one of his pockets. "That is right," as he instantly dropped it again to his side. "Obey me and you will not be hurt. Show the slightest disposition to disobey me and I will not hesitate to let you have the contents of one of these chambers, and I shall not miss you, either. Now sit down in that rocking-chair near you and put your hands upon the arms."
