There was a fortune in the business, he declared, which was the discovery of a new alloy, lighter than aluminium, yet with twenty times the rigidity.

That evening we dined together at the "Trocadero," looked in at the Empire, and returned to the club for a smoke.

Indeed, I was delighted to have found an old friend just when I was in deepest despair of the dullness of everything, and of Christmas in particular.

Otto Engler had one failing—his impudent inquisitiveness. After he had left me it occurred to me that all the time we had been together he had been constantly endeavouring to discover my recent movements, where I had visited of late, where I intended spending Christmas, and my subsequent movements.

Why did he desire to know all these particulars? He was a busybody, I knew, and the worst gossip in the whole of that gossip-loving city on the Weser. Therefore I attributed his inquisitiveness to his natural propensity for prying into other people's affairs.

"Ah! my dear friend," he had said as he gripped my hand on leaving me, "they often speak of you in Bremen. How we all wish you were back again with us of an evening at the Wiener Café!"

"I fear I shall never go back," I said briefly. "Business nowadays keeps me in London, as you know."

"I know—I know," he replied. "Remember, you have always had a true friend in Otto Engler—and you always will, I trust."

Then he had entered the taxi which the hall-porter had called for him.

Next afternoon he called upon me at New Stone Buildings, as we had arranged. Ray Raymond was seated with me. I introduced him, and we spent a pleasant hour, chatting and smoking. Ray had also been in Bremen, and the two men had, they found, many mutual friends. Then, when he had left, Ray declared himself charmed by him.
