In about ten minutes he was brought downstairs. His appearance was most unprepossessing. He was very short, with a huge head and a remarkable shock of coal-black hair. Having hastily risen from bed, he had retained his pyjamas, but a long frock-coat hung nearly to his slippers, and in one hand he carried a pair of gloves, and in the other a huge eccentric silk hat of the true chimney-pot type. These were details, and one might have passed them over. But the man's face was sadly against him. He had the slyest eyes I have ever seen; that peculiar shifty glance which invariably sets one against an individual. And thus I became more and more convinced that we had to deal with some piece of trickery. We entered the smoking-room where the gas was burning low. A gentleman stopping at the hotel was snoring in solitary state in one of the arm chairs. Reaching a table near a window we sat down and at once engaged in battle. 'I have not brought you a definite answer,' said Wareham to the envoy, 'but this gentleman is in M. Zola's confidence, and wishes further proof of your bona fides before allowing you to see M. Zola.' Then I took up the tale, now in French, now in English, for the envoy spoke both languages. Who was he? I asked. Did he claim to have received Labori's card from Labori himself? What was the document in the envelope which he would only deliver to M. Zola in person? And he replied that he was a diamond-broker. Did I know So-and-So and So-and-So of Hatton Garden? They knew him well, they did business with him; they could vouch for his honorability. But no, I was not acquainted with So-and-So and So-and-So. I never bought diamonds. Besides, it was ten o'clock on Saturday night, and the parties mentioned were certainly not at their offices for me to refer to them. Afterwards the little envoy began to speak of his family connections and his Paris friends, mentioning various well-known names. But the proofs I desired were not forth-coming; and when he finally admitted that he had not received Maitre Labori's card from that gentleman himself, all my suspicions revived. True he added that it had been given him by a well-known Revisionist leader to whom Maitre Labori, in a moment of emergency, having nobody of his own whom he could send abroad, had handed it.
