"But beyond all this, and beyond giving a detailed description of her brother's appearance, the poor girl had very little to say, and the detective who was put in charge of the case could only assure her that enquiries would at once be instituted in every possible direction, and that the police would keep her informed of everything that was being done. Obviously, the person most likely to be able to throw some light upon the mystery was Lady Angela Buckley, but as you know, the advent of this charming lady upon the scene only helped to complicate matters. It appears that Henry Buckley, delighted at what he jocosely called, 'Old "Square-toes" falling from grace,' had rung up his sister in order to tell her the startling news over the telephone. Lady Angela being a very modern young woman, her brother thought that she might storm for a bit but in the end see the humorous side of the situation. But not at all! Lady Angela took the affair entirely _au tragique_. Over the telephone she only exclaimed, 'Great Lord!' but at one o'clock in the afternoon she arrived at the flat, having taken the first train up to town and not even waiting for her maid to pack her things. Mr. Henry Buckley was just going out to lunch. Without condescending to explain anything, his sister dragged him off then and there to Scotland Yard. 'Something has happened to Denver,' was all that she would say. 'Something dreadful, I am sure.' In vain did her brother protest that she would only be making a fool of herself by rushing to the police like this, that old Square-toes had only gone on the spree, and that, anyway, she ought to consult with the Shillingtons before doing anything silly; Lady Angela would not listen to reason. 'You don't know! You don't know!' she kept on reiterating with ever-increasing agitation. 'He has been murdered, I tell you. Murdered!' "By the time that the pair arrived at Scotland Yard, Lady Angela was in a state bordering on hysterics, and her brother appeared both sulky and perplexed. They saw the same Inspector who had interviewed Miss Shillington, and certainly his amazement was no whit less than that of Mr. Henry Buckley when Lady Angela having mentioned the disappearance of Captain Denver Shillington, said abruptly, 'Yes, he has disappeared, and incidentally, he had my pearls in his pocket.' The Inspector made no immediate comment; men of his calling are used to those kinds of surprises, but Henry Buckley gave a gasp of horror. "'Your pearls?' he exclaimed. 'What pearls? Not----?' "'Yes,' Lady Angela rejoined, coolly. 'The Glenarm pearls. All of them!' "'But----' Henry Buckley stammered, wide-eyed and white to the lips. "His sister threw him what appeared to be a warning glance, then she turned once more to the police inspector.
