As the minutes slipped by without incident, Forrester grew restless. The necessity of remaining absolutely motionless to prevent making any noise cramped his muscles, and the continued silence in the impenetrable darkness grated upon his nerves. He had expected action of some kind, yet it almost seemed now as if he were doomed to disappointment. He remembered that on other occasions detectives had waited there throughout the night, only to discover in the morning that their quarry had come and gone. Was this about to happen once more? Had the package over which he and the detectives were watching already been removed? It hardly seemed possible, in view of the precautions which the detectives had taken. He had a feeling, too, that somewhere in that silent darkness, others beside the detectives and himself were concealed. He did not hear a sound, however, outside of the occasional stirring of the leaves as a gentle breeze passed through the woods. Suddenly, far down the lane, Forrester heard a slight creak that seemed to him like the application of the brake on an automobile. Listening intently, he felt sure that he could also hear the soft purr of an idling engine. At last they must be coming! Strain his ears as he might, however, Forrester could detect no other sound. If anyone were approaching the tree it was with a catlike tread that no human ear could hear. Then, in a moment, everything changed. There was a short, sharp exclamation, followed by stifled oaths and the rush of feet. Forrester could tell from the rustling of leaves on the ground and the cracking of twigs that a struggle was taking place. He longed to rush forward and help, yet reason told him that it was better to leave the matter in the hands of the detectives until they were sure of their men. The next moment the darkness was scattered by two electric pocket lamps and Forrester recognized Cahill and O’Connor standing halfway between the road and the tree, each with a man in his grasp. Forrester darted across the road, but at the same moment there came a blinding flash of light that blotted out everything about him. This was followed by shouts and oaths and several pistol shots. The flash had lasted for only a second, but the intensity of the light, followed by utter darkness, left Forrester practically blinded, and he stood helpless in the road. He did not know which way to turn, or what had happened, until an electric pocket lamp once more spread its rays across the road. Forrester then saw that the man who held it remained alone in front of the tree, and he hurried over to join him. "What happened?" cried Forrester. "That’s what I’d like to know," growled the man, who proved to be Cahill. Just then another pocket lamp flashed out. It was held by O’Connor, who now approached from the roadway and joined them. "No use," groaned O’Connor, "they got away. I stood no chance chasin’ an automobile."
