"Yes. Have you found anything unhealthful here?"
"Why, no," replied Tom, wonderingly. "We like it here. The landlord couldn't be nicer, and we're in a good location."
"Nevertheless, I fear I shall have to ask you to change your quarters," went on the major, and by the quizzical smile on his face the boys guessed that there was something in the wind.
"Let me ask you another question," went on the French officer. "Have you been annoyed since you have been here?"
"Annoyed? How?" inquired Tom.
"By unwelcome visitors, or by strangers."
The boys thought for a moment.
"There's one chap who lives in the same building here, whom we've seen on our staircase several times," said Jack, slowly. "Once I saw him pause at our door with a key, as though he were going to enter, but he heard me coming, and, muttering that he had taken too much wine and was a bit hazy in his memory, he went on upstairs."
"I thought as much," the major said. "Was the man you speak of familiar to you?"
"No, I can't say that he was," replied Jack, and Tom nodded his acquiescence. "I never saw him before."
