“What!” cried the astonished Luke.

“I happen to be aware,” continued the diplomatist, calmly, “that there is a certain fact which our friend from Ohio would give half his fortune to know. He certainly would very willingly sign the little document for it, that would put Mr. Quincunx and Miss Traffio into a position of complete security. It is only a question of ‘the terrain of negotiation,’ as we say in our ecclesiastical circles.”

Luke Andersen’s eyes opened very widely, and the amazement of his surprise made him look more like an astounded faun than ever—a faun that has come bolt upon some incredible triumph of civilization.

“I will be quite plain with you, young man,” said the theologian. “It has come to my knowledge that you and Gladys Romer are more than friends; have been more than friends, for a good while past.

“Do not wave your hand in that way! I am not speaking without evidence. I happen to know as a positive fact that this girl is neither more nor less than your mistress. I am also inclined to believe—though of this, of course, I cannot be sure—that, as a result of this intrigue, she is likely, before the autumn is over, to find herself in a position of considerable embarrassment. It is no doubt, with a view to covering such embarrassment—you understand what I mean, Mr. Andersen?—that she is making preparations to have her marriage performed earlier than was at first intended.”

“God!” cried the astounded youth, losing all self-possession, “how, under the sun, did you get to know this?”

Mr. Taxater smiled. “We poor controversialists,” he said, “have to learn, in self-defence, certain innocent arts of observation. I don’t think that you and your mistress,” he added, “have been so extraordinarily discreet, that it needed a miracle to discover your secret.”

Luke Andersen recovered his equanimity with a vigorous effort. “Well?” he said, rising from his seat and looking anxiously at his brother, “what then?”

As he uttered these words the young stone-carver’s mind wrestled in grim austerity with the ghastly hint thrown out by his companion. He divined with an icy shock of horror the astounding proposal that this amazing champion of the Faith was about to unfold. He mentally laid hold of this proposal as a man might lay hold upon a red-hot bar of iron. The interior fibres of his being hardened themselves to grasp without shrinking its appalling treachery.

Luke had it in him, below his urbane exterior, to rend and tear away every natural, every human scruple. He had it in him to be able to envisage, with a shamelessness worthy of some lost soul of the Florentine’s Inferno, the fire-scorched walls of such a stark dilemma. The palpable suggestion which now hung, as it were, suspended in the air between them, was a suggestion he was ready to grasp by the throat.
