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.
And yet a curious reluctancy, a hesitation inexplicable--unless overwork explained it--had come over him when Siward had proposed their dining together on the very eve of his completed victory over Quarrier.
It seemed absurd, and Plank was too stolid to entertain superstitions, but he could not, even with Leila laughing there beside him, shake off the dull instinct that all was not well--that Quarrier's attitude was still the attitude of a dangerous man; that he, Plank, should have had this evening in his room alone to study out the matters he had so patiently plodded through in the long hours while Siward slept.
Yet not for one instant did he dream of shifting the responsibility--if responsibility entailed blame--on Siward, who, against Plank's judgment and desire, had on the very eve of consummation drawn him away from that sleepless vigilance which must for ever be the price of a business man's safety.
