door-knobs, turn out to be a secret-service agent, and have at the same time, if not the characteristics of a fine gentleman, those at least of a man of education and sensibility infinitely superior to the highest type of day-laborer or detective. One of her new acquaintances talked like a gentleman and claimed to be the son of a distinguished man; the other, claiming nothing, was infinitely more presentable; and there was only the small boy who remained frankly representative of his class.
