“Yes,” said Mrs. Vendenning aggressively, “unless you expect him to flop down on his knees to-night. Do you?”

“I don't—to-night. Perhaps to-morrow. I don't know; I can't tell yet.” And to her maid she nodded that they were at home to Captain Voucher.

Quarrier had met him, too, just as he was leaving the hotel lobby. They exchanged the careful salutations of men who had no use for one another. On the Englishman's clean-cut face a deeper hue settled as he passed; on Quarrier's, not a trace of emotion; but when he entered his motor he sat bolt upright, stiff-backed and stiff-necked, his long gray-gloved fingers moving restlessly over his pointed heard.

The night was magnificent; myriads of summer stars spangled the heavens. Even in the reeking city itself a slight freshness grew in the air, although there was no wind to stir the parched leaves of the park trees, among which fire-flies floated—their intermittent phosphorescence breaking out with a silvery, star-like brilliancy.

Plank, driving his big motor northward through the night, Leila Mortimer beside him, twice mistook the low glimmer of a fire-fly for the distant lamp of a motor, which amused Leila, and her clear, young laughter floated back to the ears of Sylvia and Siward, curled up in their corners of the huge tonneau. But they were too profoundly occupied with each other to heed the sudden care-free laughter of the young matron, though in these days her laughter was infrequent enough to set the more merciless tongues wagging when it did sound.

Plank had never seen fit to speak to her of her husband's scarcely veiled menace that day he had encountered him in the rotunda of the Algonquin Trust Company. His first thought was to do so—to talk it over with her, consider the threat and the possibility of its seriousness, and then come to some logical and definite decision as to what their future relations should be. Again and again he had been on the point of doing this when alone with Leila—uncomfortable, even apprehensive, because of their frank intimacy; but he had never had the opportunity to do so without deliberately dragging in the subject by the ears in all its ugliness and implied reproach for her imprudence, and seeing that dreadful, vacant change in Leila's face, which the mere mention of her husband's name was sure to bring, turn into horror unspeakable.

A man not prone to fear his fellows, he now feared Mortimer, but that fear struck him only through Leila—or had so reached him until the days of his closing struggle with Quarrier. Whether the long strain had unnerved him, whether minutely providing against every possible danger he had been over-scrupulous, over-anxious, morbidly exact—or whether a foresight almost abnormal had evoked a sinister possibility—he did not know; but that threat of Mortimer's to involve Plank with Leila in one common ruin, that boast that he was able to do so could not be ignored as a possible weapon if Quarrier should by any chance learn of it.

In all his life he had taken Leila into his arms but once; had kissed her but once—but that once had been enough to arm Mortimer with danger from head to foot. Some prying servant had either listened or seen—perhaps a glimmer of a mirror had betrayed them. At all events, whoever had seen or heard had informed Mortimer, and now the man was equipped; the one and only man in all the world who could with truth accuse Plank; the only man of whom he stood in honest fear.

And it was characteristic of Plank that never for one moment had it occurred to him that the sheer fault of it all lay with Leila; that it was her imprudence alone that now threatened herself and the man she loved—that threatened his very success in life as long as Mortimer should live.

All this, Plank, in his thorough, painstaking review of the subject, had taken into account; and he could not see how it could possibly bear upon the matters now finally to be adjusted between Quarrier and himself, because Quarrier was in New York and Mortimer in Saratoga, and unless the latter had already sold his information the former could not strike at him through knowledge of it.
