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.
