“I have never taken any pledge,” said Mr. Cupples, examining his mutton with a favourable eye. “I simply don’t care about wine. I bought a bottle once and drank it to see what it was like, and it made me ill. But very likely it was bad wine. I will taste some of yours, as it is your dinner, and I do assure you, my dear Trent, I should like to do something unusual to show how strongly I feel on the present occasion. I have not been so delighted for many years. To think,” he reflected aloud as the waiter filled his glass, “of the Manderson mystery disposed of, the innocent exculpated, and your own and Mabel’s happiness crowned—all coming upon me together! I drink to you, my dear friend.” And Mr. Cupples took a very small sip of the wine.

“You have a great nature,” said Trent, much moved. “Your outward semblance doth belie your soul’s immensity. I should have expected as soon to see an elephant conducting at the opera as you drinking my health. Dear Cupples! May his beak retain ever that delicate rose-stain!—No, curse it all!” he broke out, surprising a shade of discomfort that flitted over his companion’s face as he tasted the wine again. “I have no business to meddle with your tastes. I apologize. You shall have what you want, even if it causes the head-waiter to perish in his pride.”

When Mr. Cupples had been supplied with his monastic drink, and the waiter had retired, Trent looked across the table with significance. “In this babble of many conversations,” he said, “we can speak as freely as if we were on a bare hillside. The waiter is whispering soft nothings into the ear of the young woman at the pay-desk. We are alone. What do you think of that interview of this afternoon?” He began to dine with an appetite.

Without pausing in the task of cutting his mutton into very small pieces Mr. Cupples replied: “The most curious feature of it, in my judgement, was the irony of the situation. We both held the clue to that mad hatred of Manderson’s which Marlowe found so mysterious. We knew of his jealous obsession; which knowledge we withheld, as was very proper, if only in consideration of Mabel’s feelings. Marlowe will never know of what he was suspected by that person. Strange! Nearly all of us, I venture to think, move unconsciously among a network of opinions, often quite erroneous, which other people entertain about us. I remember, for instance, discovering quite by accident some years ago that a number of people of my acquaintance believed me to have been secretly received into the Church of Rome. This absurd fiction was based upon the fact, which in the eyes of many appeared conclusive, that I had expressed myself in talk as favouring the plan of a weekly abstinence from meat. Manderson’s belief in regard to his secretary probably rested upon a much slighter ground. It was Mr Bunner, I think you said, who told you of his rooted and apparently hereditary temper of suspicious jealousy.... With regard to Marlowe’s story, it appeared to me entirely straightforward, and not, in its essential features, especially remarkable, once we have admitted, as we surely must, that in the case of Manderson we have to deal with a more or less disordered mind.”

Trent laughed loudly. “I confess,” he said, “that the affair struck me as a little unusual.

“Only in the development of the details,” argued Mr. Cupples. “What is there abnormal in the essential facts? A madman conceives a crazy suspicion; he hatches a cunning plot against his fancied injurer; it involves his own destruction. Put thus, what is there that any man with the least knowledge of the ways of lunatics would call remarkable? Turn now to Marlowe’s proceedings. He finds himself in a perilous position from which, though he is innocent, telling the truth will not save him. Is that an unheard-of situation? He escapes by means of a bold and ingenious piece of deception. That seems to me a thing that might happen every day, and probably does so.” He attacked his now unrecognizable mutton.

“I should like to know,” said Trent, after an alimentary pause in the conversation, “whether there is anything that ever happened on the face of the earth that you could not represent as quite ordinary and commonplace by such a line of argument as that.”

A gentle smile illuminated Mr. Cupples’s face. “You must not suspect me of empty paradox,” he said. “My meaning will become clearer, perhaps, if I mention some things which do appear to me essentially remarkable. Let me see .... Well, I would call the life history of the liver-fluke, which we owe to the researches of Poulton, an essentially remarkable thing.”

“I am unable to argue the point,” replied Trent. “Fair science may have smiled upon the liver-fluke’s humble birth, but I never even heard it mentioned.”

“It is not, perhaps, an appetizing subject,” said Mr. Cupples thoughtfully, “and I will not pursue it. All I mean is, my dear Trent, that there are really remarkable things going on all round us if we will only see them; and we do our perceptions no credit in regarding as remarkable only those affairs which are surrounded with an accumulation of sensational detail.”
