The man obeyed, and the watcher ran back to his post. He was desperately hoping the affair would terminate to-night. He was growing weary of this eternal vigilance; and it was only his fear of the man known as the boss that kept him at his post. He wanted a night to carouse in, to be with the boys. The man for whom they were lying in wait was seen presently to creep cautiously round the side of the house. He hugged a corner and paused. They could see the dim outline of his body. The light in the street back of the grounds almost made a silhouette of him. By and by, as if assured that the coast was clear, he stole down to the street. "Halt!" Instantly the prowler took to his heels. Two shots rang out. The man was seen to stop, stagger, and then go on desperately. "He's hit!" By the time the men reached the corner they heard the rumble of a motor. One dashed back to the car they had left standing at the curb. He made quick work of the job, but he was not quick enough. Still, they gave chase. They saw the car turn toward the city. But, unfortunately for the success of the chase, several automobiles passed, going into town and leaving it. Checkmate. Braine was keen enough to-night. "He is hit; whether badly or not remains to be seen. We can find that out. Drive to the nearest drug store and get a list of hospitals. It's a ten to one shot that we land him somewhere among the hospitals." But they searched the hospitals in vain. None of them had that night received a shooting case, nor had they heard one reported. The man had been unmistakably hit. He would not have dared risk the loss of time for a bit of play-acting. Evidently he had kept his head and sought his lodgings. To call up doctors would be utter folly; for it would take a week for a thorough combing. This was the second time the man had got away. "Perhaps I'm to blame," admitted Braine. "I should have advised Miles to stalk him and pot him if he got the chance. There's a master mind working somewhere back of all this, and it's time I woke up to the fact. But you," turning to the auto bandits, "you men have your instructions. More than that, you have been given a free rein. See that you make good, or by the Lord Harry! I'll break the four of you like pipestems." "We haven't had a failure yet," spoke up one of the men, more courageous than his companions. "You are not holding up a bank messenger this trip. Remember that. Drive me as far as Columbus Circle. Leave me on the side street, between the lights, so I can take off this mask."
