Who is he? We do not know. He is always spoken of by the unassuming title of 'Mr. Brown.' But one thing is certain, he is the master criminal of this age. He controls a marvellous organization. Most of the Peace propaganda during the war was originated and financed by him. His spies are everywhere."
"A naturalized German?" asked Tommy.
"On the contrary, I have every reason to believe he is an Englishman. He was pro-German, as he would have been pro-Boer. What he seeks to attain we do not know—probably supreme power for himself, of a kind unique in history. We have no clue as to his real personality. It is reported that even his own followers are ignorant of it. Where we have come across his tracks, he has always played a secondary part. Somebody else assumes the chief rôle. But afterwards we always find that there has been some nonentity, a servant or a clerk, who has remained in the background unnoticed, and that the elusive Mr. Brown has escaped us once more."
"Oh!" Tuppence jumped. "I wonder"
"Yes?"
"I remember in Mr. Whittington's office. The clerk—he called him Brown. You don't think"
Carter nodded thoughtfully.
"Very likely. A curious point is that the name is usually mentioned. An idiosyncrasy of genius. Can you describe him at all?"
"I really didn't notice. He was quite ordinary—just like any one else."
Mr. Carter sighed in his tired manner.
