This mysterious communication roused my curiosity. Who was the party that was said to be gone at last? Where had he come from? where had he been hiding, that I had not seen him? and where was he gone to now? I determined to know; if but the opportunity would offer, to screw, by cunning questioning, the secret out of either of the three.

Fate favored my design.

For some inscrutable reason, known only to the company’s officials, we cheap-trainers were not permitted to proceed on our journey to London along with the mail, but were left to kick our heels for some two hours at the Dover station.

I went into the refreshment-room to look for my party; I had a notion I should find them where the Briton’s unswerving and unerring instinct would be most likely to lead them. It turned out that I was right in my conjecture. There they were, seated round a table with huge bowls of steaming tea and monster piles of buttered toast and muffins spread on the festive board before them. Ay, indeed, there they were; but quantum mutati ab illis! how strangely changed from the noisy, rollicking set I had known them in the railway-car and on board the steamer, ere yet the demon of sea-sickness had claimed them for his own! How ghastly sober they looked now, to be sure! And how sternly and silently bent upon devoting themselves to the swilling of the Chinese shrub infusion and to the gorging of indigestible muffins. It was quite clear to me that it would have been worse than folly to venture upon addressing them while thus absorbed in absorbing. So I resolved to await a more favorable opening, and went out meanwhile to walk on the platform.

A short time I was left in solitary possession of the promenade; then I became suddenly aware that another traveller was treading the same ground with me—it was the dark elderly leader of the three. I glanced at him as he passed me under one of the lamps. He looked pale and sad. The furrowed lines on his brow bespoke deliberation deep and pondering profound. All the infinite mirth of the preceding few hours had departed from him, leaving him but a wretched wreck of his former reckless self.

“A fine night, sir,” I said to break the ice—“for the season of the year,” I added by way of a saving clause, to tone down the absoluteness of the assertion.

He looked at me abstractedly, merely reëchoing my own words, “A fine night, sir, for the season of the year.”

“Why look ye so sad now, who were erst so jolly?” I bluntly asked, determined to force him into conversation.

“Ay, indeed, why so sad now?” he replied, looking me full in the face; then, suddenly clasping my arm with a spasmodic grip, he continued hurriedly, “I think I had best confide our secret to you. You seem a man of thought. I witnessed and admired the patient attention with which you listened to your friend’s abstruse talk in the railway-car. Maybe you can find the solution of a mystery which defies the ponderings of our poor brains—mine and my two friends.”

Then he proceeded to pour into my attentive ear this gruesome tale of mystery:
