"That's queer," spoke Tom.
"Very," agreed Ned. "He didn't go back after all. I'd like to know what's going on in there."
"And there's someone else who would like to know, also, I think," said Tom in a low voice.
"Who?" asked Ned.
"That man hiding behind the big tree across the street. I'm sure he's watching the Foger house, and when Andy came to the door that time, I happened to look around and saw that man focus a pair of opera glasses on him and the carpenter."
"You don't mean it, Tom!" exclaimed Ned.
"I sure do. I believe that man is some sort of a spy or a detective."
"Do you think he's after Andy?"
"I don't know. Let's not get mixed up in the affair, anyhow. I don't want to be called in as a witness. I haven't the time to spare."
As if the man behind the tree was aware that he had attracted the attention of our friends, he quickly turned and walked away. Tom and Ned glanced up at the Foger house, but saw nothing, and proceeded on to the store.
