Strong man as he was, Van Zwieten reeled half-fainting against the wall. It was true--the box was gone! In a flash he realized his peril. For that box held little that was not of a highly compromising nature. Once its contents were seen by the authorities--as it would seem they must be--he would be arrested as a spy, imprisoned, perhaps hanged. No ingenuity or lying on his part could explain away the damning evidence of the papers. They spoke for themselves.

What a fool he had been not to have forwarded them to Leyds in the morning as he had intended to do. Now it was too late, and nothing remained but to fly to Pretoria and to throw in his lot openly with his employers. Useless now to think of going out as correspondent to an English newspaper, even were he able to manage his escape from London. Those in command at the front would surely be advised of his true character by the home authorities; and not only that, but he would be unmasked in a country under military law, where a spy such as he would receive but short shrift. Fly he must, and that at once. He must get to the Continent, and take ship for Delagoa Bay. The game was up in England; there remained now only the Transvaal.

After the first emotion of terror had passed, Van Zwieten collected his wits and set to work to find some way out of the difficulty. Had he been in Russia or France he would have given himself up to despair, for there the authorities were lynx-eyed and relentless. But here in England he was amongst a people so firmly wedded to their old-fashioned laws as to freedom and justice that they might fail to take the strong measures which the situation, so far as they were concerned, demanded. He would baffle these pig-headed islanders yet, and, with a courage born of despair, he set himself to the accomplishment of this design.

Mrs. Hicks, pale and tearful, had followed him into the room and had been witness of his despair. The poor woman was too much agitated to speak. This unexpected invasion of her quiet house by the police had been altogether too much for her. Van Zwieten made her sit down, and proceeded to question her. With many tears and lamentations that she had no husband to protect her, she gave him all the necessary details, and he listened with feverish anxiety to every word.

"It was about midday, Mr. Jones," said Mrs. Hicks; "yes, I will not deceive you, sir, the clock was just on twelve when I heard a ring at the door. I left Mary Anne in the kitchen and went to see who it was. There was a hansom at the door, sir, and standing on the mat there was a policeman and a lady."

"A lady?" put in Van Zwieten, looking rather puzzled, for he could not guess what woman could have interfered with his affairs. He had always kept himself clear of the sex. "What lady?"

"I don't rightly know her name, Mr. Jones, for, to be plain with you, she never gave it to me. She was a short lady, sir, with black hair and eyes--as black as your hat, sir."

"Dressed in mourning?" asked the Dutchman, with a sudden flash of intuition.

"As you say, sir--dressed in mourning, and beautifully made it was, too. She asked if Mr. Jones lived here, and if he was at home. I said you did lodge with me, sir, having no reason to hide it, but that you were out. The lady stepped into the passage then with the policeman."

"What was the policeman like?"
