“Very soon, however, that theory was also bound to collapse. Mr. Fairburn, whose reputation as an investigator of crime waxes in direct inverted ratio to his capacities, did hit upon the obvious course of interviewing the managers of the larger London and Liverpool agents de change. He soon found that Prince Semionicz had converted a great deal of Russian and French money into English banknotes since his arrival in this country. More than £30,000 in good solid, honest money was traced to the pockets of the gentleman with the sixteen quarterings. It seemed, therefore, more than improbable that a man who was obviously fairly wealthy would risk imprisonment and hard labour, if not worse, for the sake of increasing his fortune by £10,000.
“However, the theory of the Prince’s guilt has taken firm root in the dull minds of our police authorities. They have had every information with regard to Prince Semionicz’s antecedents from Russia; his position, his wealth, have been placed above suspicion, and yet they suspect and go on suspecting him or his secretary. They have communicated with the police of every European capital; and while they still hope to obtain sufficient evidence against those they suspect, they calmly allow the guilty to enjoy the fruit of his clever roguery.”
“The guilty?” said Polly. “Who do you think—”
“Who do I think knew at that moment that young Schwarz had money in his possession?” he said excitedly, wriggling in his chair like a jack-in-the-box. “Obviously someone was guilty of that theft who knew that Schwarz had gone to interview a rich Russian, and would in all probability return with a large sum of money in his possession?”
“Who, indeed, but the Prince and his secretary?” she argued. “But just now you said—”
“Just now I said that the police were determined to find the Prince and his secretary guilty; they did not look further than their own stumpy noses. Messrs. Winslow and Vassall spent money with a free hand in those investigations. Mr. Winslow, as the senior partner, stood to lose over £9000 by that robbery. Now, with Mr. Vassall it was different.
“When I saw how the police went on blundering in this case I took the trouble to make certain inquiries, the whole thing interested me so much, and I learnt all that I wished to know. I found out, namely, that Mr. Vassall was very much a junior partner in the firm, that he only drew ten percent of the profits, having been promoted lately to a partnership from having been senior assistant.
“Now, the police did not take the trouble to find that out.”
“But you don’t mean that—”
“I mean that in all cases where robbery affects more than one person the first thing to find out is whether it affects the second party equally with the first. I proved that to you, didn’t I, over that robbery in Phillimore Terrace? There, as here, one of the two parties stood to lose very little in comparison with the other—”
“Even then—” she began.
“Wait a moment, for I found out something more. The moment I had ascertained that Mr. Vassall was not drawing more than about £500 a year from the business profits I tried to ascertain at what rate he lived and what were his chief vices. I found that he kept a fine house in Albert Terrace. Now, the rents of those houses are £250 a year. Therefore speculation, horse-racing or some sort of gambling, must help to keep up that establishment. Speculation and most forms of gambling are synonymous with debt and ruin. It is only a question of time. Whether Mr. Vassall was in debt or not at the time, that I cannot say, but this I do know, that ever since that unfortunate loss to him of about £1000 he has kept his house in nicer style than before, and he now has a good banking account at the Lancashire and Liverpool bank, which he opened a year after his ‘heavy loss.’ ”
“But it must have been very difficult—” argued Polly.
“What?” he said. “To have planned out the whole thing? For carrying it out was mere child’s play. He had twenty-four hours in which to put his plan into execution. Why, what was there to do? Firstly, to go to a local printer in some out-of-the-way part of the town and get him to print a few cards with the high-sounding name. That, of course, is done ‘while you wait.’ Beyond that there was the purchase of a good secondhand uniform, fur coat, and a beard and a wig from a costumier’s.
“No, no, the execution was not difficult; it was the planning of it all, the daring that was so fine. Schwarz, of course, was a foreigner; he had only been in England a little over a fortnight. Vassall’s broken English misled him; probably he did not know the junior partner very intimately. I have no doubt that but for his uncle’s absurd British prejudice and suspicions against the Russian Prince, Schwarz would not have been so ready to believe in the latter’s roguery. As I said, it would be a great boon if English tradesmen studied Gotha more; but it was clever, wasn’t it? I couldn’t have done it much better myself.”
That last sentence was so characteristic. Before Polly could think of some plausible argument against his theory he was gone, and she was trying vainly to find another solution to the Liverpool mystery.

The Edinburgh Mystery
The man in the corner had not enjoyed his lunch. Miss Polly Burton could see that he had something on his mind, for, even before he began to talk that morning, he was fidgeting with his bit of string, and setting all her nerves
