Siward he had not turned out of his way to injure; Siward had been in the way, that was all, and his ruin was to have been merely an agreeable coincidence with the purposed ruin of Amalgamated Electric before Inter-County absorbed the fragments. But here was a new phase; Mrs. Mortimer, whom he had expected to use, and if necessary sacrifice, had suddenly turned vicious. And he now hated her as coldly as he hated Major Belwether for betraying suspicions of a similar nature. As for Plank, fear and hatred of him was becoming hatred and contempt. He had the means of checking Plank if Mortimer did not drop dead before midnight. There remained Sylvia, whom he had selected as the fittest object attainable to transmit his name. Long ago, whatever of liking, of affection, of passion he had ever entertained for her had quieted to indifference and the unemotional contemplation of a future methodically arranged for. Now of a sudden, this young girl he had bought—he knowing what she sold and what he was paying for—had become exposed to the infection of a suspicion concerning himself and another woman; a woman unmarried, and of his own caste, and numbered among her own friends.

And he knew enough of Sylvia to know that if anybody could once arouse her suspicion nothing on earth could induce her to look into his face again. Suppose Leila should do so this evening?

Certainly Quarrier had several matters to ponder over and provide for; and first and foremost of all to provide for his own security and the vital necessity of preserving his name and his character untainted. In this he had to deal with that miserable judge who had betrayed him; with Mortimer, who had once black-mailed him and who now was temporarily in his service; with Mrs. Mortimer, who—God knew how, when, or where—had become suspicious of Agatha and himself; with Major Belwether, who had deserted him before he could sacrifice the major, and whom he now hated and feared for having stumbled over suspicions similar to Mrs. Mortimer's. He had to deal with Sylvia herself, and with Siward—reckon with Siward's knowledge of matters which it were best that Sylvia should not know.

But first of all, and most important of all, he had to deal with Beverly Plank. And he was going to do it in a manner that Plank could not have foreseen; he was going to stop Plank where he stood, and to do this he was deliberately using his knowledge of the man and paying Plank the compliment of counting on his sense of honour to defeat him.

For he had suddenly found the opportunity to defend himself; he had discovered the joint in Plank's old-fashioned armour—the armour of the old paladins—who placed a woman's honour before all else in the world. Now, through his creature, Mortimer, he could menace Plank with a threat to involve him and Leila in a vile publicity; now he was in a position to demand a hearing and a compromise through his new ambassador, Mortimer, knowing that he could at last halt Plank by threatening Leila with this shameful danger. Plank must sign the truce or face with Leila an action for damages and divorce.

First of all he went to the Lenox Club and dressed. Then he dined sparingly and alone. The Mercedes was waiting when he came out ready to run down to the great Hotel Corona, whither the Japanese steward had conducted Mortimer. Mortimer had dined heavily, but his disorganised physical condition was such that it had scarcely affected him at all.

Again Quarrier went over patiently and carefully the very simple part he had reserved for Mortimer that evening, explaining exactly what to say to Leila and what to say to Plank in case of insolent interruption. Then he told Mortimer to be ready at nine o'clock, turned on his heel with a curt word to the Japanese, descended to the street, entered his motor-car again, and sped away to the Hotel Santa Regina.

Miss Caithness was at home, came the message in exchange for his cards for Agatha and Mrs. Vendenning. He entered the gilded elevator, stepped out on the sixth floor into a tiny, rococo, public reception-room. Nobody was there besides himself; Agatha's maid came presently, and he turned and followed her into the large and very handsome parlour belonging to the suite which Agatha was occupying with Mrs. Vendenning for the few days that they were to stop in town.

“Hello,” she said serenely, sauntering in, her long, pale hands bracketed on her narrow hips, her lips disclosing her teeth in a smile so like that nervous muscular recession which passed for a smile on Quarrier's visage that for one moment he recognised it and thought she was mocking him. But she strolled up to him, meeting his eye calmly, and lifted her slim neck, lips passive under his impetuous kiss.

“Is Mrs. Vendenning out?” he asked, laying his hands on the bare shoulders of the tall, pallid girl—tall as he, and as pallid.
