The reddish-orange glow of a lighted cigarette emanated from the dark living room, a glow that brightened with each drag and alternately waned with each exhale. An ashtray overflowed with a dozen discarded butts while the smell of cigarette smoke permeated the living quarters of the high-rise condominium on Chicago's lakefront locally known as the Gold Coast.
