subs. (venery).A person set to watch a DRESS-LODGER (q.v.).
1869. GREENWOOD, The Seven Curses of London. Not alone. Dress lodgers are never allowed to do that, sir. I havent been one long, but long enough to find that out. Theres always a WATCHER. Sometimes its a womanan old woman, who isnt fit for anything elsebut in general its a man. He watches you always, walking behind you, or on the opposite side of the way. He never loses sight of you, never fear.
