CHAPTER XIV
DICK MAKES A DISCOVERY
While the boys were discussing the situation one of the night clerks of the hotel arrived, having been summoned by the hallman. He listened with interest to what the lads had to tell.
"I'll set the house detective on this," he said. "We can't allow anybody to prowl around, trying to use false keys."
"We want to catch that man ourselves," said Dick. "We are going to set a watch for him. No more sleep for us to-night."
"I don't blame you," returned the clerk. "If you spot him, call up the office and we'll give you all the help you want."
The boys hurried into their clothing, and then, led by Dick, walked noiselessly through the various hallways of the big hotel in the direction where the oldest Rover boy had heard the door shut. But though they passed many doors, Dick could not determine which was the right one.
