"Right, sir!" said the man. And then their pewters clinked.

To my chagrin this was all the conversation. The Viscount strode out alone—except for my company. The fog had grown deeper, and I was glad to be conducted to the station. This time we went to Liverpool Street. Dorking lingered at the book-stall, and at last enquired if they had yesterday's Times. Receiving a reply in the negative, he clucked his tongue impatiently. Then, as with a sudden thought, he ran up to the North London Railway book-stall, only to be again disappointed. He took out the great coloured handkerchief, and wiped his forehead. Then he entered into confidential conversation with an undistinguished stranger, fat and foreign, who had been looking eagerly up and down at the extreme end of the platform. Re-descending into the street, he jumped into a Charing Cross 'bus. As he went inside I had no option but to go outside, though the air was yellow and I felt chilled to the bone.

IN CONFIDENTIAL CONVERSATION WITH AN UNDISTINGUISHED FOREIGNER.

Alighting at Charing Cross, he went into the telegraph office, and wrote a telegram. The composition seemed to cause him great difficulty. Standing outside the door, I saw him discard two half-begun forms. When he came out I made a swift calculation of the chances, and determined to secure the two forms, even at the risk of losing him. Neither had an address. One read: "If you are still set on your fol—"; the other: "Come to-night if you are still—" Bolting out with these precious scraps of evidence, that only added fuel to the flame of curiosity that was consuming me, I turned cold to find the Viscount swallowed up in the crowd. After an instant's agonised hesitation, I hailed a hansom, and drove to his flat in Victoria Street. The valet told me the Viscount was ill in bed, and could not see me. I read in his face that it was a lie. I resolved to loiter outside the building till Dorking's return.

I had not long to wait. In less than ten minutes a hansom discharged him at my feet. Had I not been prepared for anything, I should not have recognised him again in his red whiskers, white hat, and blue spectacles. He rang the bell, and enquired of his own valet if Viscount Dorking was at home. The man said he was ill in bed.

"Oh, we'll soon put him on his legs again," interrupted Dorking, with a professional air, and pushed his valet aside. In that moment the solution dawned upon me. Dorking was mad! Nothing but insanity would account for his day's vagaries. I felt it was my duty, as a fellow-creature, to look to him. I followed him, to the open-eyed consternation of the valet. Suddenly he turned upon me, and seized me savagely by the throat. I felt choking. My worst fear was confirmed.

"No further, my man," he cried, flinging me back. "Now go, and tell her ladyship how you have earned your fee!"

"Dorking! are you mad?" I gasped. "Don't you remember me—Mr. Pry—from the Bachelor's Club?"

"Great heavens, Paul!" he cried. Then he fell back on an ottoman, and laughed till the whiskers ran down his sides. He always had a sense of humour, I remembered.
