But, of course, the Sicilian would return to the charge, and equally, of course, Mrs. Tadworth would sacrifice the Shuttleworths, father and son, to save her own skin. Lady Molly knew that. She is strong, active and determined; she had a brief hand-to-hand struggle with Mrs. Tadworth that night, and finally succeeded in tying her, half unconscious, to the bedpost, thus assuring herself that for at least twenty-four hours that vapid little fool would be unable to either act for herself or to betray my dear, intrepid lady’s plans. When, the following morning, Piatti opened the door of No. 118, which had purposely been left on the latch, he was greeted with the sight of Mrs. Tadworth pinioned and half dead with fear, whilst the valuable proofs of his own guilt and young Shuttleworth’s innocence had completely disappeared. For remember that Lady Molly’s face was not known to him or to his gang, and she had caught the first train to Cividale even whilst Piatti still believed that he held that silly Mrs. Tadworth in the hollow of his hand. I may as well tell you here that she reached the frontier safely, and was quite sharp enough to seek out Colonel Grassi and, with the necessary words of explanation, to hand over to him the proofs of young Shuttleworth’s innocence. My action in the matter helped her. At the hotel she was supposed to be the mistress and Mrs. Tadworth the maid, and everyone was told that “Mrs. Carey’s maid” had been assaulted, and removed to the hospital. But I denounced Piatti then and there, thinking he had attacked my dear lady, and I got him put under lock and key so quickly that he had not the time to communicate with his associates. Thanks to Colonel Grassi’s exertions, young Shuttleworth was acquitted of the charge of murder; but I may as well tell you here that neither Piatti nor his son, nor any of that gang, were arrested for the crime. The proofs of their guilt--the Irish-tweed coat and the murdered man’s watch and chain--were most mysteriously suppressed, after young Shuttleworth’s advocate had obtained the verdict of “not guilty” for him. Such is the Sicilian police. Mr. Shuttleworth, senior, evidently knew what he was talking about. Of course, we had no difficulty in obtaining Lady Molly’s release. The British Consul saw to that. But in Budapest they still call the assault on “Mrs. Carey” at the Hotel Hungaria a mystery, for she exonerated Lady Molly fully, but she refused to accuse Piatti. She was afraid of him, of course, and so they had to set him free. I wonder where he is now, the wicked old wretch! IV. THE FORDWYCH CASTLE MYSTERY Can you wonder that, when some of the ablest of our fellows at the Yard were at their wits’ ends to know what to do, the chief instinctively turned to Lady Molly?
