"I regret very much," I said, "but I've already arranged to dine with my friend Raymond, who shares chambers with me in Lincoln's Inn."

"Oh!" exclaimed Otto Engler, "I'm sure Herr Griesbach would be very pleased if he came also."

"Of course!" cried the German merrily. "The more the merrier. We shall dine at eight, and we'll expect you both. I'll send a note to Mr. Raymond, if you'll give me his address."

I gave it to him, and nothing loath to spend the festival in such jovial company, I accepted.

I entertained a shrewd suspicion that by their hospitality they wished to enlist my aid, because I had one or two friends in the City who might, perhaps, assist them materially in their scheme. And yet, after all, Otto Engler had often been my guest in Bremen.

Next day I heard on the telephone from Ray that he would go down to Barnes with me, and would call for me at six at Guilford Street. Curiously enough, I had become so impressed by the possibilities of the new alloy about to be exploited with British capital, that I had really become anxious to "go in" with them. Ray Raymond, too, was much interested when I showed him the specimen of the new metal which Engler had given me.

"Do you know," said he when he called for me at six o'clock on Christmas evening, "I was about town a lot yesterday and I'm quite certain that I was followed by a foreigner—a rather big man wearing gold spectacles."

"Nonsense!" I laughed. "Why should you be followed by any foreigner?"

"It isn't nonsense, my dear Jacox," he declared. "The fellow kept close observation on me all yesterday afternoon. When I got back to Bruton Street, I looked out half an hour afterwards and there he was, still idling outside."

"Some chap who wants to serve you with a writ, perhaps!" I laughed grimly. "A neglected tailor's bill!"
