did not know where Fitzgerald lived, and as the detective wanted to find out, he determined to watch Brian's movements and trace him home.
"If he's that pretty girl's lover, I'll wait till he leaves the house," argued Mr. Gorby to himself, when he first took his seat on the Esplanade. "He won't stay long away from her, and once he leaves the house, I'll follow him up till I find out where he lives."
