"I hope you are not in debt, ma'am," he said to the landlady; "that man looks to me like a bailiff in disguise." "I manage to pay my way, sir, though it is a hard struggle," the woman replied.

"And you didn't think of asking him ?" "It was very stupid of me, sir--I only asked him how he came to know that I let apartments.
