A Royal Wrong by Fred M. White

With a terrible pain at his heart, Childers glanced up and down the platform. The lights were turned low, and one or two figures crept about in the gloom. Childers could see the placards over the bookstall, one illustrating a serial story particularly caught his eye. It represented a girl falling backwards from a train. It was an ominous suggestion, but Hugh put it from him. There was a chance that Lady Letty might have been detained till the very last moment. Some accident might have happened the car. He dared not let his fears carry him beyond this possibility.

At any rate, they would gain a few precious moments, for Lady Violet Ringwood had not yet turned up. Du Cros might fuss and fume, but he was scarcely likely to order the train to proceed without giving his expected guest plenty of grace. The Ringwoods were not the sort of people whom a millionaire of the modern type would care to offend on slight provocation.
