poised in his fingers, half-way to his lips, with the minutest relaxing of the smile that still hovered about them, while a dull and ashen grayness crept into his face, second by waiting second.

It was not until his eyes met hers that he took three wavering and undecided steps toward her.

With a silent movement—more of warning than of fright, he afterward told himself—she pressed her gloved fingers to her lips. What her intent eyes meant to say to him, in that wordless, telepathic message, Durkin could not guess; all thought was beyond him. But in a moment or two the roadway cleared, the car shook and plunged forward, the floating curtains fluttered and trailed behind.

Durkin turned blindly, and pushed and ran and dodged through the languidly amazed promenaders, following after that sudden and bewildering vision, as after his last hope in life. But the fine, white, limestone Riviera dust from the fading car's tire-heels, and the burnt gases from its engines, were all the road held for him, as it undulated off into hillside quietnesses.

He heard the young Chicagoan calling after him, breathless and anxious. But he ran on until he came to a side street, shadowed with garden walls and villas and greenery. Slipping into this, he immured himself in the midnight silences, to be alone with the contending forces that tore at him.

If his companion was right, and such things as this made up Romance, then, after all, the drama of life had lost none of its bewilderment. For the woman he had seen between the floating purple curtains was his own wife.

CHAPTER III

THE SHADOWING PAST

Durkin's first tangible feeling was a passion to lose and submerge himself in the muffling midnight silences, the silences of those outwardly quiet gardens at heart so old in sin and pain.

He felt the necessity for some sudden and sweeping readjustment, and his cry for solitude was like that of the child wounded in spirit, or that of the wild animal sorely hurt in body. Before he could face life again, he felt, he had to build up about him the sustaining fabric of some new and factitious faith.

But as intelligence slowly emerged from the mist and chaos of utter bewilderment, as reason crept haltingly back to her seat, his first blind and indeterminate rage fell away from him. His first black and blinding clouds of suspicion slowly subsided before practical and orderly question and cross-question. Thought adjusted itself to its new environment. Painfully, yet cautiously, he directed his ceaseless artillery of interrogation toward the outer and darker walls of uncertainty still so blankly confronting him.

It was not that he had been consumed by any direct sense of loss, of deprivation. It was not that he had feared open and immediate treachery. If a rage had burned through him, at the sudden and startling sight of his own wife thus secretly masquerading in an unknown rôle, it was far from being a rage or mere jealousy and distrust.

They had, in other days, each passed through questionable and perilous experiences. Both together and alone they had adventured unwillingly along many of the more dubious channels of life. They had surrendered to temptation; they had sown and reaped and suffered, and become weary of it. They had struggled slowly yet stoically up towards respectability; they had fought for fair-dealing; they had entered a compact to stand by each other through that long and bitter effort to be tardily honest and autumnally aboveboard.

What now so disturbed and disheartened him was the sudden sense of something impending, the vague apprehension of some momentous and far-reaching intrigue which he could not even foreshadow. And it was framing itself into being at a time when he had most prayed for their untrammelled freedom, when he had most looked for their ultimate emancipation from the claws of that too usurious past.

But, above all, what had brought about the sudden change? Why had no inkling of it crept to his ears? Why was she, the passionate pleader for the decencies of life whom he had last watched so patiently and heroically imparting the mastery of the pianoforte to seven little English children in a squalid Paris pension, now lapsing back into the old and fiercely abjured avenue of irresponsibility? Why had she weakened and surrendered, when he himself, the oldtime weakling of the two, had clung so desperately to the narrow path of rectitude? And what was the meaning and the direction of it all? And what would it lead to? But why, above all, had she kept silent, and given him no warning?

Durkin looked up and listened to the soft rustling of the palm branches. The bray of a distant band saddened him with an unfathomable sense of homesickness. Through an air that seemed heavy with languid tropicality, and the waiting richness of life, he caught the belated glimmer of lights and the throb and murmur of string music. It carried in to him what seemed the essential and alluring note of all the existence he had once known and lived. Yet day by day he had fought back that sirenic call. It had not always been an open victory—the weight of all the past lay too heavily upon him for that—but for her sake he had at least vacillated and hesitated and temporized, waiting and looking for that final strength which would come with her first wistful note of warning, or with her belated return to his side.

Yet here was Opportunity lying close and thick about him; here Chance had laid the board for its most tempting game. In that way, as the young Chicagoan had said, they stood in the centre of the world. But he had turned away from those clustering temptations, he had left unbroken his veneer of honorable life, for her sake—while she herself had surrendered, unmistakably, irrevocably, whatever strange form the surrender might even at that moment be taking.

All he could do, now, was to wait until morning. There would surely be some message, some hint, some key to the mystery. While everything remained so maddeningly enigmatic, he raked through the tangled past in search of some casual seed of explanation for that still undeciphered present.

He recalled, period by period, and scene by scene, his kaleidoscopic past career, his first fatal blunder as a Grand Trunk telegraph operator, when one slip of the wrist brought a gravel train head-on into an Odd Fellows' Excursion special, his summary dismissal from the railroad, and his unhappy flight to New York, his passionate struggle to work his way up once more, his hunger for money and even a few weeks of leisure, that his long dreamed of photo-telegraphy apparatus might be perfected and duly patented, his consequent fall from grace in the Postal-Union offices, through holding up a trivial racing-return or two until he and his outside confederate had been able to make their illicit wagers, then his official ostracism, and his wandering street-cat life, when, at last, the humbling and compelling pinch of poverty had turned him to "overhead guerrilla" work and the dangers and vicissitudes of a poolroom key-operator. He recalled his chance meeting with MacNutt, the wire-tapper, and their partnership of privateer forces in that strange campaign against Penfield, the alert and opulent poolroom king, who had seemed always able to defy the efforts and offices of a combative and equally alert district-attorney.

Most vividly and minutely of all, he reviewed his first meeting with Frances Candler, and the bewilderment that had filled him when he discovered her to be an intimate and yet a reluctant associate with MacNutt in his work—a bewilderment which lasted until he himself grew to realize how easy was the downward trend when once the first false step had been made.

He brought back to mind their strange adventures and perils and escapes together, day by day and week by week, their early interest that had ripened into affection, their innate hatred of that underground life,
