“It’s only because,—er,—when I dashed into the building, I noticed something very odd about the fire.”

“Just what do you mean?”

“Well, as we ran up to the house, we noticed smoke pouring out of the front door. I dashed inside by the back door and then I saw that most of the smoke and fire seemed to be at the threshold of the front door. Now that is very odd.”

“Yes, you are quite right, my boy,” answered Captain Bob. “As a matter of fact, the front door caved in first. However, I came to the fire a little too late to really judge the cause or origin of the fire. But it did seem to me that there was something odd about the whole thing.”

“Was there anything about the fire that would lead you to believe that it was an accident or perhaps—er,—otherwise?” asked Paul, pressing his point.

Captain Bob scratched his chin thoughtfully and said, “My dear boy, you are asking some very serious questions that may get you into trouble.”

Paul insisted. “Just the same, would you form an opinion?”

“No, I really couldn’t because, as I said before, I came to the fire too late. I had no chance to look into the cause of the fire and now that the house is a heap of ashes, the chances of finding any clue is very slight. Suppose you tell me your opinion, my boy.”

“To be quite frank, Captain, I think that the fire was started by some pyromaniac.”

The Captain sat up in his chair. “What makes you think so?” he demanded suddenly.
