Having got so far, all that remained to be done was to find out to what "nineteen-twelve" referred. He turned to the dictionary again, and looked for the twelfth word upon the nineteenth page. This proved to be "Alkahest," which told him nothing. So he reversed the proceedings and looked for the nineteenth word upon the twelfth page; but this proved even less satisfactory than before. However much the dictionary might have helped him hitherto, it was plainly useless now. He thought and thought, but without success. He turned up the almanac, but the dates did not fit in. He then wrote the letters of the alphabet upon a sheet of paper, and against each placed its equivalent number. The nineteenth letter was S, the twelfth L. Did they represent two words, or were they the first and the last letters of a word? In that case, what could it be. The only three he could think of were _soil_, _sell_ and _sail_. The two first were hopeless, but the last seemed better. But how would that fit in? He took up his pen and tried it. Owing to O’Grady’s silence, the Society in Chicago is growing uneasy. Two men, who are the first and last, or, in other words, the principal members, sail to-day with fifty thousand somethings, probably pounds or dollars, so prepare bombs. NERO. He felt convinced that he had hit it at last. Either it was a very extraordinary coincidence, or he had discovered the answer to the riddle. If this solution were correct, one thing was certain, he had got in his hands, quite by chance, a clue to one of the biggest Fenian conspiracies ever yet brought to light. He remembered that at that moment London contained half the crowned heads, or their representatives, of Europe. What better occasion could the enemies of law and order desire for striking a blow at the Government and society in general? What was he to do? To communicate with the police and thus allow himself to be drawn into the affair, would be an act of the maddest folly; should he therefore drop the whole thing, as he had at first proposed, or should he take the matter into his own hands, help Mrs. Jeffreys in her trouble by shipping her father out of harm’s way, outwit the Fenians, and appropriate the fifty thousand pounds mentioned in the cablegram himself? The last idea was distinctly a good one. But, before it could be done, he felt he must be certain of his facts. Was the fifty thousand referred to money or was it something else? If the former, was it pounds or was it dollars? There was a vast difference, but in either case, if only he could hit on a safe scheme, he would be well repaid for whatever risk he might run. He decided to see Mrs. Jeffreys without loss of time. Accordingly, after breakfast, he sent her a note asking her to call upon him, without fail, at twelve o’clock.
