Van Dorn detectives shadowed them so discreetly from the 20th Century’s LaSalle Street Station to the Golden State’s Dearborn Station that even Bell only spotted them twice. Once aboard the Golden State, he asked a Van Dorn agent costumed as a conductor if they’d been followed. He was assured, categorically, no. Bell figured it was quite likely true. Joseph Van Dorn had founded the agency in Chicago. The detectives headquartered in the Palmer House were top-notch and proud of it. THE GOLDEN STATE LIMITED WAS a transcontinental express that would stop only at major stations along a 2,400-mile run south and west on the low-altitude El Paso Route. A luxurious “heavyweight,” it consisted of a drawing room sleeper, a stateroom and drawing room sleeper, a stateroom car of smaller cabins—where Bell had again booked top and bottom berths—the dining car, and a buffet-library-observation car in the back of the train. Mail, baggage, and express cars rode at the front end directly behind the tender that carried coal and water for the Pacific 4-6-2 locomotive.
