No sooner had he got round a corner than he started running at a rate that gave me a stitch in the side. He did not stop till he reached a cab-rank. There was only one vehicle on it, and the coughing, red-nosed driver, unpleasantly suggesting a mixture of grog and fog, was climbing to his seat when I came cautiously and breathlessly up, and Dorking was returning to his trousers' pocket a jingling mass of gold and silver coins, which he had evidently been exhibiting to the sceptical cabman. He seemed to walk these regions with the fearlessness of Una in the enchanted forest. I had no resource but to hang on to the rear, despite the alarums of "whip behind," raised by envious and inconsiderate urchins.

And in this manner, defiantly dodging the cabman, who several times struck me unfairly behind his back, I drove through a labyrinth of sordid streets to the Bethnal Green Museum. Here we alighted, and the Viscount strolled about outside the iron railings, from time to time anxiously scrutinising the church clock and looking towards the fountain which only performs in the summer, and was then wearing its winter night-cap. At last, as if weary of waiting, he walked with sudden precipitation towards the turnstile, and was lost to view within. After a moment I followed him, but was stopped by the janitor, who, with an air of astonishment, informed me there was sixpence to pay, it being a Wednesday. I understood at once why the Viscount had selected this day, for there was no one to be seen inside, and it was five minutes ere I discovered him. He was in the National Portrait Gallery, before one of Sir Peter Lely's insipid beauties, which to my surprise he was copying in pencil. Evidently he was trying to while away the time. At eleven o'clock to the second he scribbled something underneath the sketch, folded it up carefully, picked up his bundle and walked unhesitatingly downstairs into the second gallery, where, after glancing about to assure himself that the policeman's head was turned away, he deposited the paper between two bottles of tape-worms, and stole out through the back door. Feverishly seizing the sketch, I followed him, but the policeman's eye was now upon me, and I had to walk with dignified slowness, though I was in agonies lest I should lose my man. My anxiety was justified; when I reached the grounds, the Viscount was nowhere to be seen. I ran hither and thither like a madman, along the back street and about the grounds, hacking my shins against a perambulator, and at last sank upon a frigid garden seat, breathless and exhausted. I now bethought me of the paper clenched in my fist, and, smoothing it out, deciphered these words faintly pencilled beneath a caricature of the Court beauty:—

"Not my fault you missed me. If you are still set on your folly, you will find me lunching at the Chingford Hotel."

I sprang up exultant, new fire in my veins. True, the mystery was darkening, but it was the darkness that precedes the dawn.

"Cherchez la femme!" I muttered, and darting down Three Colts Lane I reached the Junction, only to find the barrier dashed in my face. But half-a-crown drove it back, and I sprang into the guard's van on his very heels. A shilling stifled the oath on his lips, and transferred it to mine when I discovered I had jumped into the Enfield Fast. Before I really got to Chingford it was long past noon. But I found him.

The Viscount was toying with a Chartreuse in the dining-room. The waiters eyed me suspiciously, for I was shabby and dusty and haggard-looking. To my surprise Dorking had doffed the sailor, and wore a loud checked suit! He looked up as I entered, but did not appear to recognise me. There was no one with him. Still I had found him. That was the prime thing.

Becoming conscious I was faint with hunger, I took up the menu, when to my vexation I saw the Viscount pay his bill, and don an overcoat and a billy-cock, and ere I could snatch bite or sup I was striding along the slimy forest paths, among the gaunt, fog-wrapped trees, following the Viscount by his footprints whenever I lost him for a moment among the avenues. Dorking marched with quick, decisive steps. In the heart of the forest, by a great oak, whose roots sprawled in every direction, he came to a standstill. Hidden behind some brushwood, I awaited the sequel with beating heart.

The Viscount took out a great coloured handkerchief, and spread it carefully over the roots of the oak; then he sat down on the handkerchief, and whistled the same bar of the same once popular air he had whistled outside the coffee-house. Immediately a broken-nosed man emerged from behind a bush, and addressed the Viscount. I strained my ears, but could not catch their conversation, but I heard Dorking laugh heartily, as he sprang up and clapped the man on the shoulder. They walked off together.

I was now excited to the wildest degree; I forgot the pangs of baffled appetite; my whole being was strung to find a key to the strange proceedings of the mathematical Viscount. Tracking their double footsteps through the mist, I found them hobnobbing in a public-house on the forest border. After peeping in, I ran round to another door, and stood in an adjoining bar, where, without being seen, I could have a snack of bread and cheese, and hear all.

"Could you bring her round to my house to-night?" said Dorking, in a hoarse whisper. "You shall have the money down."
