A shade of serious discomposure crossed the open countenance of Zero.

‘There are times,’ he said, ‘when I begin to fancy that you do not like me. Why, why, dear Somerset, this lack of cordiality? I am depressed; the touchstone of my life draws near; and if I fail’—he gloomily nodded—‘from all the height of my ambitious schemes, I fall, dear boy, into contempt. These are grave thoughts, and you may judge my need of your delightful company. Innocent prattler, you relieve the weight of my concerns. And yet . . . and yet . . .’ The speaker pushed away his plate, and rose from table. ‘Follow me,’ said he, ‘follow me. My mood is on; I must have air, I must behold the plain of battle.’

So saying, he led the way hurriedly to the top flat of the mansion, and thence, by ladder and trap, to a certain leaded platform, sheltered at one end by a great stalk of chimneys and occupying the actual summit of the roof. On both sides, it bordered, without parapet or rail, on the incline of slates; and, northward above all, commanded an extensive view of housetops, and rising through the smoke, the distant spires of churches.

‘Here,’ cried Zero, ‘you behold this field of city, rich, crowded, laughing with the spoil of continents; but soon, how soon, to be laid low! Some day, some night, from this coign of vantage, you shall perhaps be startled by the detonation of the judgment gun—not sharp and empty like the crack of cannon, but deep-mouthed and unctuously solemn. Instantly thereafter, you shall behold the flames break forth. Ay,’ he cried, stretching forth his hand, ‘ay, that will be a day of retribution. Then shall the pallid constable flee side by side with the detected thief. Blaze!’ he cried, ‘blaze, derided city! Fall, flatulent monarchy, fall like Dagon!’

With these words his foot slipped upon the lead; and but for Somerset’s quickness, he had been instantly precipitated into space. Pale as a sheet, and limp as a pocket-handkerchief, he was dragged from the edge of downfall by one arm; helped, or rather carried, down the ladder; and deposited in safety on the attic landing. Here he began to come to himself, wiped his brow, and at length, seizing Somerset’s hand in both of his, began to utter his acknowledgments.

‘This seals it,’ said he. ‘Ours is a life and death connection. You have plucked me from the jaws of death; and if I were before attracted by your character, judge now of the ardour of my gratitude and love! But I perceive I am still greatly shaken. Lend me, I beseech you, lend me your arm as far as my apartment.’

A dram of spirits restored the plotter to something of his customary self-possession; and he was standing, glass in hand and genially convalescent, when his eye was attracted by the dejection of the unfortunate young man.

‘Good heavens, dear Somerset,’ he cried, ‘what ails you? Let me offer you a touch of spirits.’

But Somerset had fallen below the reach of this material comfort.

‘Let me be,’ he said. ‘I am lost; you have caught me in the toils. Up to this moment, I have lived all my life in the most reckless manner, and done exactly what I pleased, with the most perfect innocence. And now—what am I? Are you so blind and wooden that you do not see the loathing you inspire me with? Is it possible you can suppose me willing to continue to exist upon such terms? To think,’ he cried, ‘that a young man, guilty of no fault on earth but amiability, should find himself involved in such a damned imbroglio!’ And placing his knuckles in his eyes, Somerset rolled upon the sofa.
