Working together and moving cautiously, they raised up the trap door on every vestibule clear up to the baggage car. There was no one hidden on the steps. “If there was ever anyone there, he got off at Robertson,” said the conductor. But Bob shook his head. “I don’t think so,” he said firmly. “What would a man stop there for? It’s miles from any other town, and there are no good highways nearby to make a get-away in a car.” “Maybe you’re right, but there’s no one on this train.” Bob wasn’t so sure. A crafty man such as Hamsa had shown himself to be could have moved to the shelter of one of the rear vestibules while the Limited was standing at Robertson for Bob had checked these vestibules before the train stopped there. “I’m going to work from the front to the back,” declared Bob, and the conductor looked at him suspiciously as though thinking that the strain of the night might have unbalanced Bob. But he went along without complaint when the federal agent started the hunt again. Car by car they inspected the train. The small dark spot they had found in one vestibule had dried and Bob didn’t dare think what might have happened to Tully. While there was no love lost between them, Bob had no desire to see any harm come to the other. As they entered the observation car, the Limited started slowing down. The conductor, pressing his face against one of the rain-washed panes of glass, peered ahead. “Junction showing now,” he said as Bob stepped in after inspecting the trap doors on the observation platform. A red lantern was being swung at the junction platform and the minute the Limited drew to a halt beside the cinder platform Bob and the trainman started running forward. A night operator, swathed in a heavy storm coat, greeted them. “Message from Robertson for Bob Houston,” he told the conductor. “Fine thing to make a man deliver telegrams at this time of night.” The conductor didn’t bother to answer the operator’s complaint but handed the message to Bob, who tore open the envelope and read the brief message inside. “Man you reported missing found by freight crew. Has cut on head and is bruised. Otherwise appears okay. Proceeding on to junction aboard freight.” Bob breathed a sigh of relief for he was honestly glad to know that no serious harm had befallen Tully. “Are you going on with us or will you stay here?” asked the conductor. Bob hesitated for only a moment. “I’m going on,” he decided, for he knew that Tully would be placed in good hands by the railroad people and could proceed on alone to his assignment as soon as he felt well enough. In the meantime, Bob was still convinced that Joe Hamsa was somewhere aboard the Limited for he knew that Hamsa’s destination, like his own, was somewhere along the east coast of Florida and he felt sure that Hamsa would lose no time in attempting to reach it. In view of that, Bob felt the gangster would continue on the Limited.
