Diana of Kara-Kara by Edgar Wallace

Bobbie Selsbury had gone to Victoria to rescue his brother at the eleventh hour from a situation which could be mildly described as dangerous. He had searched one Continental train from end to end, and was half way through another when the guard's whistle sounded, and he was faced with the alternatives of leaving his search incomplete or going on to Dover. He decided upon the latter course, continuing his inspection of the compartments, roving Pullman cars, peeping in upon indignant honeymoon couples, without discovering the object of his search. At Dover he discovered that there had been a relief train leave Victoria at a quarter to eleven; the passengers were already on the steamer. Gordon may have come by that, he thought, and made his decision.

He had no passport, but most of the restrictions affecting Continental travel, especially travel to Belgium, had been removed, and he was able to convince the passport officer at the barrier that his business was of such urgency, and his identity so well established, that a little licence might be extended to him; and, on the promise that he would return after leaving the ship, he was allowed to pass to the quayside.
