“It’s very kind of you,” said Anthony. “We’re all here, I see. Then I can get on with the good work.” “I don’t understand,” said George Lomax weightily. “I don’t understand in the least. This is all very irregular. Mr. Cade has no standing—no standing whatever. The position is a very difficult and delicate one. I am strongly of the opinion——” George’s flood of eloquence was arrested. Moving unobtrusively to the great man’s side, Superintendent Battle whispered a few words in his ear. George looked perplexed and baffled. “Very well, if you say so,” he remarked grudgingly. Then added in a louder tone, “I’m sure we are all willing to listen to what Mr. Cade has to say.” Anthony ignored the palpable condescension of the other’s tone. “It’s just a little idea of mine, that’s all,” he said cheerfully. “Probably all of you know that we got hold of a certain message in cipher the other day. There was a reference to Richmond, and some numbers.” He paused. “Well, we had a shot at solving it—and we failed. Now in the late Count Stylptitch’s Memoirs (which I happen to have read) there is a reference to a certain dinner—a ‘Flower’ dinner which every one attended wearing a badge representing a flower. The Count himself wore the exact duplicate of that curious device we found in the cavity in the secret passage. It represented a Rose. If you remember, it was all _rows_ of things—buttons, letter E’s, and finally rows of knitting. Now, gentlemen, what is there in this house that is arranged in rows? Books, isn’t that so? Add to that, that in the catalogue of Lord Caterham’s library there is a book called _The Life of the Earl of Richmond_, and I think you will get a very fair idea of the hiding-place. Starting at the volume in question, and using the numbers to denote shelves and books, I think you will find that the—er—object of our search is concealed in a dummy book, or in a cavity behind a particular book.” Anthony looked round modestly, obviously waiting for applause. “Upon my word, that’s very ingenious,” said Lord Caterham. “Quite ingenious,” admitted George condescendingly. “But it remains to be seen——” Anthony laughed. “The proof of the pudding’s in the eating—eh? Well, I’ll soon settle that for you.” He sprang to his feet. “I’ll go to the library——” He got no further. M. Lemoine moved forward from the window. “Just one moment, Mr. Cade. You permit, Lord Caterham?” He went to the writing-table and hurriedly scribbled a few lines. He sealed them up in an envelope, and then rang the bell. Tredwell appeared in answer to it. Lemoine handed him the note. “See that that is delivered at once, if you please.” “Very good, sir,” said Tredwell. With his usual dignified tread he withdrew. Anthony, who had been standing, irresolute, sat down again. “What’s the big idea, Lemoine?” he asked gently. There was a sudden sense of strain in the atmosphere.
