gravely and looked from one boy to the other.
“Who?”
“Captain Bob.”
The announcement came as a shock, almost overwhelming them. Each boy searched the face of the other for some meaning or understanding. But all of them were just as puzzled. Paul repeated the name, “Captain Bob! But why should he follow us?”
Ken shrugged his shoulders. “Are you sure it was he?” questioned Jack, his demeanor grave and serious.
“I am absolutely positive. After all, I know the man. It’s true I didn’t see his face—”
Paul jumped. “You didn’t see his face!” he exclaimed. “Then how do you know it was he? You might be mistaken.”
Ken shrugged his shoulders. “Very possible,” he said, “but I am pretty sure I am not mistaken. To begin with, I know the man and I can recognize him without seeing his face. And secondly, I watched him walk down Chestnut Street and enter a house at about the middle of the street. That is where he lives, isn’t it?”
“Yes, but are you sure he walked into his own house—that is, Captain Bob’s house?” demanded Paul.
“Well, no, I didn’t follow him all the way to his home; I watched from the corner. But just the same I am pretty sure that it was Captain Bob.”
There was silence. The boys could not understand why the Captain should follow them. “Well, I’ll be!” exclaimed Jack. “This thing is getting beyond me and I am losing my patience.”
“Now don’t get excited,” cautioned Paul. “And keep quiet for a couple of minutes. I am trying to think of something.”
“Think of what?” asked Ken.
“Of what he said to us when we were over to see him,” was the answer.
“What about it?”
Paul leaned over toward his two companions. “Now look, fellows,” he began. “There is one particular thing he told us that comes back to me now very distinctly. You remember how just as we were leaving, he said to us, ‘Don’t you go around talking about a pyromaniac; it may get you into trouble.’ Remember him saying that?”
Jack nodded. “Yes, I remember.”
“Same here,” added Ken, “now that you call our attention to it. But what about it? He meant it for our own good.”
“Of course,” said Paul, “I am not doubting his sincerity. But, Captain Bob is much shrewder than we give him credit for, that’s the point.”
“How do you mean?” inquired Jack.
“We came over to talk over with him the fire, didn’t we?” continued Paul. “Well, remember that he didn’t seem to have a very definite opinion though he did feel that there was something odd about the cause or origin of the fire.”
“Well, what’s your point?” demanded Ken, his curiosity aroused.
“Only this,” said Paul, “that since we told him of our own doubts about the fire and that since we told him we suspected a pyromaniac, he immediately came to the conclusion that we knew more than we were telling him. And in order to find out what we may know about the fire, he is following us.”
“Sounds logical to me,” muttered Jack.
Ken shook his head. “It may sound logical,” he said, “but somehow I am not convinced. How should he know we were going out to Water Street this morning? And he would have to watch the house of any one of us three all morning to follow us. And why should he pick this morning to follow us?”
Paul smiled at his friend’s naive questions. “To begin with,” he said, “how do we know he has not been following us since that night we spoke to him? But I am under the impression that his following us is just an accident.”
“An accident!” echoed Jack. “Explain yourself.”
“I will if you don’t interrupt. My impression is that he was coming to Water Street this morning also to search for some clues to the fire. But when he saw us there, he naturally watched us to see what we were up to and then followed us.”
Ken shook his head in a gesture of disbelief. Jake, on the other hand mused quietly, trying to untangle the whole situation, but unable to find a starting point. Finally he asked, “Do you think he will continue to follow us, Paul?”
“Can’t tell. He may and he may not.”
After a short time of silence, Jack rose and suggested, “Well, let’s go home for lunch.”
“That’s a bully idea,” cried Ken. “I didn’t realize how hungry I am.”
“All right, I’ll see you boys later,” said Paul.
That evening, immediately after supper, Paul went across the street to call for Ken. As the two boys walked down the street, Paul whispered, “We are being followed.”
Ken gasped. “Captain Bob!” he exclaimed in a hushed tone of voice.
“Don’t know. But for the last half hour I noticed that someone was hovering about the house. And as we came out and walked away, I noticed a form slink out of the shadows and follow us.”
“What do you think we ought to do?”
“I have an idea.” And he whispered some instructions to his friend.
Ken nodded. “And then what?” he asked.
“Leave the rest to me.”
When the two boys arrived in front of Jack’s home, Paul spoke up rather loudly, “I guess I’ll walk down the block and call Nuthin’. I’ll be back in about five minutes.”
“All right,” answered Ken just as loudly. “Jack and I will wait for you.”
Ken entered the yard while Paul walked off straight ahead. Turning in at the end of the street, he set off at a run around the block.
Returning to the same street at the other end, he hovered close to the wall of a building and looked everywhere to detect the hiding place of the spy. Suddenly he caught his breath. He detected a slight movement behind a fence at the other side of the street, several houses below. He crossed to the other side and walked ahead. Sure enough, a man stepped out and came toward him. As they met, Paul greeted, “Hello, Captain Bob.”
The man grunted and was going to pass on, but Paul instantly got into his way. The man stopped, “Huh?” he muttered. “Did you speak to me?”
“I said hello, Captain Bob.”
“Hello yourself. Now let me see, your face seems to be familiar, but I can’t seem to remember your name.”
“Paul Morrison.”
“Oh, yes, yes. You are the boy who dashed into the burning house and—”
Paul interrupted. “Yes, that’s right; you know me.” What a poor actor the man was, Paul thought. He certainly couldn’t get away with pretending that he didn’t know him. His
