“I only looked in as I passed,” said he. “I am going right on.”

“Where to?”

“Oh, to the other side of the West End. It may be some time before I get back. Don’t wait up for me in case I should be late.”

“How are you getting on?”

“Oh, so so. Nothing to complain of. I have been out to Streatham since I saw you last, but I did not call at the house. It is a very sweet little problem, and I would not have missed it for a good deal. However, I must not sit gossiping here, but must get these disreputable clothes off and return to my highly respectable self.”

I could see by his manner that he had stronger reasons for satisfaction than his words alone would imply. His eyes twinkled, and there was even a touch of color upon his sallow cheeks. He hastened up-stairs, and a few minutes later I heard the slam of the hall door, which told me that he was off once more upon his congenial hunt.

I waited until midnight, but there was no sign of his return, so I retired to my room. It was no uncommon thing for him to be away for days and nights on end when he was hot upon a scent, so that his lateness caused me no surprise. I do not know at what hour he came in, but when I came down to breakfast in the morning, there he was with a cup of coffee in one hand and the paper in the other, as fresh and trim as possible.

“You will excuse my beginning without you, Watson,” said he; “but you remember that our client has rather an early appointment this morning.”

“Why, it is after nine now,” I answered. “I should not be surprised if that were he. I thought I heard a ring.”

It was, indeed, our friend the financier. I was shocked by the change which had come over him, for his face, which was naturally of a broad and massive mould, was now pinched and fallen in, while his hair seemed to me at least a shade whiter. He entered with a weariness and lethargy which was even more painful than his violence of the morning before, and he dropped heavily into the arm-chair which I pushed forward for him.
