CHAPTER VI
The Spy
The following morning, immediately after breakfast, the three boys met and set off for Water Street. At the scene of the fire, Jack pointed out the approximate spot where the man had sat and wept. Searching for footprints, they found many, most of them indistinct and smudged. They continued their search for other possible clues but found none. In the midst of their searchings, however, Paul looking up thought he saw a flitting shadow duck behind a fence across the street. Making believe that he saw nothing, he bent over and continued his investigations; however, he had his eyes glued to the spot. And sure enough, he saw a head protrude. He was amazed. Was it possible that someone was spying on them? Was it possible that the person Jack had followed the evening before had now turned around and was following them?
He called the two boys over. Pretending that he was explaining to them the outline of a footprint, he told them in a few words, of his discovery. “Don’t look now,” he warned his friends; “and don’t both look at the same time.”
Ken joked, saying, “I hope this thing hasn’t got you so that you are beginning to see things.”
“Don’t be funny,” remarked Paul seriously. “Suppose you fellows move off now. Keep an eye on the spot I pointed out to you and don’t give yourselves away.”
The boys separated and pretended to be absorbed in their investigations. They kept this up for about five minutes and then Paul called them and they walked away. “Well?” he asked anxiously.
Jack nodded. “You are right,” he whispered. “I also saw the head protruding from behind the fence watching us.”
“What about you, Ken? Did you see anything?”
