Lady Georgina, very flustered and hot by this time, tumbled out once more, and bolted back to the _coupe_. Both trains were just starting. In her hurry, at last, she let the Count take possession of her jewel-case. I rather fancy that as he passed one window he handed it in to the shabby-looking passenger; but I am not certain. At any rate, when we were comfortably seated in our own compartment once more, and he stood on the footboard just about to enter, of a sudden he made an unexpected dash back, and flung himself wildly into a Paris carriage. At the self-same moment, with a piercing shriek, both trains started. Lady Georgina threw up her hands in a frenzy of horror. 'My diamonds!' she cried aloud. 'Oh, Lois, my diamonds!' 'Don't distress yourself,' I answered, holding her back, for I verily believe she would have leapt from the train. 'He has only taken the outer shell, with the sandwich-case inside it. _Here_ is the steel box!' And I produced it, triumphantly. She seized it, overjoyed. 'How did this happen?' she cried, hugging it, for she loved those diamonds. 'Very simply,' I answered. 'I saw the man was a rogue, and that he had a confederate with him in another carriage. So, while you were gone to the _buffet_ at Ostend, I slipped the box out of the case, and put in the sandwich-tin, that he might carry it off, and we might have proofs against him. All you have to do now is to inform the conductor, who will telegraph to stop the train to Paris. I spoke to him about that at Ostend, so that everything is ready.' She positively hugged me. 'My dear,' she cried, 'you are the cleverest little woman I ever met in my life! Who on earth could have suspected such a polished gentleman? Why, you're worth your weight in gold. What the dickens shall I do without you at Schlangenbad?' II THE ADVENTURE OF THE SUPERCILIOUS _ATTACHE_ The Count must have been an adept in the gentle art of quick-change disguise; for though we telegraphed full particulars of his appearance from Louvain, the next station, nobody in the least resembling either him or his accomplice, the shabby-looking man, could be unearthed in the Paris train when it drew up at Brussels, its first stopping-place. They must have transformed themselves meanwhile into two different persons. Indeed, from the outset, I had suspected his moustache--'twas so _very_ distinguished. When we reached Cologne, the Cantankerous Old Lady overwhelmed me with the warmth of her thanks and praises. Nay, more; after breakfast next morning, before we set out by slow train for Schlangenbad, she burst like a tornado into my bedroom at the Cologne hotel with a cheque for twenty guineas, drawn in my favour. 'That's for you, my dear,' she said, handing it to me, and looking really quite gracious. I glanced at the piece of paper and felt my face glow crimson. 'Oh, Lady Georgina,' I cried; 'you misunderstand. You forget that I am a lady.'
