The Midnight Passenger is a mystery by Richard Henry Savage. Excerpt: The pulses of the young man were vaguely thrilled with the coming of spring, and so he complacently took in the never-ceasing tide of eager women, on the street's shady side, with one comprehensive and kindly glance. For six long years he had cautiously studied that same sea of always anxious faces! He well knew all the types from the disdainful woman of fashion, the crafty daughter of sin, the vacuous country visitor, down to the argus-eyed mere de famille, sternly resolute in her set purpose of making three dollars take the place of five, by some heaven-sent bargain. Countless times he had threaded this restless multitude, with an alert devotion to the interests of the Western Trading Company. He was, to the ordinary lounger, but the type of the average well-groomed New York business man. And yet, his watchful eyes swept keenly to right and left, as he breasted the singularly inharmonious waves of the weaker sex.
