With the certainty of danger, Isaac's fear seemed to vanish into thin air. He saw the open door of his ransacked inner room and the piled-up heap of weapons upon the table. Face to face with actual danger, the, courage of a wild animal at bay seemed suddenly vouchsafed to him.

"Come with you to Hell!" he cried. "I think not, Mr. Inspector. Are these the witnesses against me?"

He pointed to Ruth and Arnold. Ruth clutched her stick and staggered tremblingly to her feet.

"How can you say that, Isaac!" she exclaimed. "Arnold and I have only been home from the country a few minutes. We walked into the room and found these men here. Isaac, I am terrified. Tell me that you have not done anything really wrong!"

Isaac made no reply. All the time he watched the inspector stealthily. The latter moved forward now, as though to make the arrest. Then Isaac's hand shot out from his pocket and a long stream of yellow fire flashed through the room. The inspector sprang back. Isaac's hand, with the smoke still curling from the muzzle of his pistol, remained extended.

"That was only a warning," Isaac declared, calmly. "I aimed at the wall there. Next time it may be different."

There was a breathless silence. The inspector stood his ground but he did not advance.

"Let me caution you, Isaac Lalonde," he said, "that the use of firearms by any one in your position is fatal. You can shoot me, if you like, and my assistant, but if you do you will certainly be hanged. It is my duty to arrest you and I am going to do it."

Isaac's hand was still extended. This time he had lowered the muzzle of his pistol. The inspector was only human and he paused, for he was looking straight into the mouth of it. Isaac slowly backed toward the door.

"Remember, you are warned!" he cried. "If any one pursues me, I shoot!"
