The clever criminal who wishes to escape the law does not seek provincial neighborhoods or foreign climes. He remains in London; for him no place is so safe. There a man can disappear from one district and reappear in another without danger of recognition by unwelcome friends. Of course the pertinacity of the police may do much to complicate matters, but the history of crime goes to show very clearly that they are by no means infallible. But about them Van Zwieten troubled himself very little. Certainly he changed his name to Jones, for his own, in those anti-Dutch times, smacked overmuch of Holland. But for the rest his disguise was slight. From St. James's he changed his address to a part of Westminster where none of his West End friends were likely to come across him; and as Mr. Jones he carried on his plotting against the Empire with every sense of security. And in such security he saw only a strong proof of John Bull's stupidity. An Englishman would have seen in it a glorious example of freedom. In a side street Van Zwieten, _alias_ Mr. Jones, dwelt on the first floor of a quiet house let out in lodgings by the quietest of widows. And Mrs. Hicks had a good opinion of her lodger. It is true he was somewhat erratic in his movements. For days he would go away--into the country, he said--and even when in town would be absent for many hours at a stretch. But he paid well and regularly, was not exacting about either his food or attendance, and behaved altogether in the most becoming manner. He certainly saw a great number of people, and they called on him principally at night, but Mr. Jones had kindly informed her how he was writing a great book on London, and how these people were gathering materials for him. Had Mrs. Hicks known the kind of materials they were collecting, she might or might not have been astonished. Certainly she would have been but little the wiser. A decent, if narrow-minded little person, Mrs. Hicks knew little of politics and still less of spies. These latter--on those few occasions when they had presented themselves to her mind--she pictured as foreign persons given to meeting by candlelight with mask and cloaks and daggers. That the kind gentleman who was so polite to her and so kind to her fatherless children should be a spy assuredly never entered Mrs. Hick's head.
