But I felt I must collect myself, and be ready for the important negotiation entrusted to me. And to do this I must for the time banish these fruitless efforts at solving the problem.

We had a good run to Calais, found the boat in waiting, and a fair passage brought us prosperously across the Channel. I found myself in London punctual to the intended hour of my arrival.

At once I drove to the lodgings in a small street off the Strand which I was accustomed to frequent in such circumstances. I felt nervous till I had an opportunity of thoroughly overhauling my documents. The bag had been opened by the Custom House officials, but the words "private papers" had sufficed to prevent any further examination; and to my unspeakable delight they were intact. A glance satisfied me as to this the moment I got them out, for they were most carefully numbered.

The next morning saw me early on my way to—No. 909, we will say—Blackfriars Street, where was the office of Messrs. Bluestone & Fagg. I had never been there before, but it was easy to find, and had I felt any doubt, their name stared me in the face at the side of the open doorway. "Second-floor" I thought I read; but when I reached the first landing I imagined I must have been mistaken. For there, at a door ajar, stood an eminently respectable-looking gentleman, who bowed as he saw me, with a discreet smile.

"Herr Schmidt?" he said. "Ah, yes; I was on the look-out for you."

I felt a little surprised, and my glance involuntarily strayed to the doorway. There was no name upon it, and it appeared to have been freshly painted. My new friend saw my glance.

"It is all right," he said; "we have the painters here. We are using these lower rooms temporarily. I was watching to prevent your having the trouble of mounting to the second-floor."

And as I followed him in, I caught sight of a painter's ladder—a small one—on the stair above, and the smell was also unmistakable.

The large outer office looked bare and empty, but under the circumstances that was natural. No one was, at the first glance, to be seen; but behind a dulled glass partition screening off one corner I fancied I caught sight of a seated figure. And an inner office, to which my conductor led the way, had a more comfortable and inhabited look. Here stood a younger man. He bowed politely.

"Mr. Fagg, my junior," said the first individual airily. "And now, Herr Schmidt, to business at once, if you please. Time is everything. You have all the documents ready?"
