It was ten o'clock in the morning; Calcutta lay a hundred miles up the river, approximately. By evenfall Amber expected to be in the city, whether he stuck by the steamer until she docked in the port, or left her at Diamond Harbour, sixty miles upstream, and finished his journey by rail. At the present moment he hardly knew which to do; in the ordinary course of events he would have gone ashore at Diamond Harbour, thereby gaining an hour or two in the city. But within the last eighteen hours events had been diverted from their normal course; and Amber was deeply troubled with misgivings.
Up to the day that the Poonah had sailed from Tilbury Dock, London, from the time he had left Quain among the sand-dunes of Long Island, he had not been conscious of any sort of espionage upon his movements. That gaunt and threatening figure which he had seen silhouetted against the angry dawn had not again appeared to disturb or trouble him. His journey across the Atlantic had been uneventful; he had personally investigated the saloon passenger lists, the second and third cabins and the steerage of the Lusitania, not forgetting the crew, only to be reassured by the absence of anybody aboard who even remotely suggested an Indian spy. But from the hour that the Poonah with its miscellaneous ship's company, white, yellow, brown, and black, had warped out into the Thames, he had felt he was being watched—had realised it instinctively, having nothing definite whereon to base his feeling. He was neither timorous nor given to conjuring up shapes of terror from the depths of a nervous imagination; the sensation of being under the surveillance of unseen, prying eyes is unmistakable. Yet he had tried to reason himself out of the belief—after taking all sensible precautions, such as never letting the photograph of Sophia Farrell out of his possession and keeping the Token next his skin, in a chamois bag that nestled beneath his arm, swinging from a leather cord round his neck. And as day blended into eventless day, he had lulled himself into an uneasy indifference. What if he were watched? What could it profit any one to know what he did or how he did it, day by day? And with increasing infrequency he had come to question himself as to the reason for the spying on his movements.
Possibly the fruitlessness of any such speculation had much to do with his gradual cessation of interest in the enigma. He was not credulous of the power of divination popularly ascribed to the Oriental; he was little inclined to believe that the nature of his errand to India had been guessed, or that any native intelligence in India knew or suspected the secret of Sophia Farrell's parentage—Rutton's solicitude to the contrary notwithstanding. The theory that he most favoured in explanation of the interest in him was that it had somehow become known that he bore with him the emerald. It was quite conceivable that that jewel, intrinsically invaluable, was badly wanted by its former possessors, whether for the simple worth of it or because it played an important part in the intrigue, or whatever it was, that had resulted in Rutton's suicide. For his own part, Amber cared nothing for it; he had christened it, mentally, the Evil Eye—with a smile to himself; nonetheless he half-seriously suspected it of malign properties. He was imaginative enough for that—or superstitious, if you prefer.
He would, however, gladly have surrendered the jewel to those who coveted it, in exchange for a promise of immunity from assassination, had he known whom to approach with the offer and been free to make it. But he must first show it to Dhola Baksh of the Machua Bazaar. After that, when its usefulness had been discharged, he would be glad of the chance to strike such a bargain….
Such, in short, had been his frame of mind up to eight o'clock of the previous evening. At that hour he had made a discovery which had diverted the entire trend of his thoughts.
Doggott, ever a poor sailor, had been feeling ill and Amber had excused him early in the afternoon. About six o'clock he had gone to his stateroom and dressed for dinner, unattended. Absorbed in anticipations of the morrow, when first he should set foot in Calcutta and take the first step in pursuit of Sophia Farrell, he had absent-mindedly neglected to empty the pockets of his discarded clothing. At seven he had gone to dinner, leaving his stateroom door open, as was his habit—a not unusual one with first-cabin passengers on long voyages—and his flannels swinging from hooks in the wall. About eight, discovering his oversight through the absence of his cigarette-case, he had hurried back to the stateroom to discover that he had been curiously robbed.
His watch, his keys, his small change and his sovereign purse, his silver cigarette-case—all the articles, in fact, that he was accustomed to stuff into his pockets—with one exception, were where he had left them. But the leather envelope containing the portrait of Sophia Farrell was missing from the breast-pocket of his coat.
From the hour in which he had obtained it he had never but this once let it out of his personal possession. The envelope he had caused to be constructed for its safe-keeping during his enforced inaction in London. He had never once looked at it save in strict privacy, secure even from the eyes of Doggott; and the latter did not know what the leather case contained.
Thus his preconceived and self-constructed theory as to the extent of The Enemy's knowledge, was in an instant overthrown. "They" had seized the very first relaxation of his vigilance to rob him of that which he valued most. And in his heart he feared and believed that the incident indicated "their" intimacy not alone with his secret but with that which he shared with Colonel Farrell.
Since then his every move toward regaining the photograph had been fruitless. His stateroom steward, a sleek, soft Bengali boy who had attended him all through the voyage with every indication of eagerness to oblige him, professed entire ignorance of the theft. That was only to be expected. But when Amber went to the purser and the latter cross-examined the steward in his presence, the Bengali stuck to his protestations of innocence without the tremor of an eyelash. In fact, he established an alibi by the testimony of his fellow-stewards. Further, when Amber publicly offered a reward of five guineas "and no questions asked" and in private tempted the Bengali with much larger amounts, he accomplished nothing.
