To his way of thinking the behavior of the fiacre was quite unaccountable. Hardly had the horse paced off the length of two blocks on the Quai ere it was guided to the edge of the promenade and brought to a stop. And the driver twisted the reins round his whip, thrust the latter in its socket, turned sidewise on the box, and began to smoke and swing his heels, surveying the panorama of river and sunset with complacency—a cabby, one would venture, without a care in the world and serene in the assurance of a generous pour-boire when he lost his fare. But as for the latter, she made no move; the door of the cab remained closed,—like its occupant's mind, a mystery to the watcher.
Twilight shadows lengthened, darkling, over the land; street-lights flashed up in long, radiant ranks. Across the promenade hotels and shops were lighted up; people began to gather round the tables beneath the awnings of an open-air café. In the distance, somewhere, a band swung into the dreamy rhythm of a haunting waltz. Scattered couples moved slowly, arm in arm, along the riverside walk, drinking in the fragrance of the night. Overhead stars popped out in brilliance and dropped their reflections to swim lazily on spellbound waters.... And still the fiacre lingered in inaction, still the driver lorded it aloft, in care-free abandon.
In the course of time this inertia, where he had looked for action, this dull suspense when he had forecast interesting developments, wore upon the watcher's nerves and made him at once impatient and suspicious. Now that he had begun to doubt, he conceived it as quite possible that Mrs. Hallam (who was capable of anything) should have stolen out of the cab by the other and, to him, invisible door. To resolve the matter, finally, he took advantage of the darkness, turned up his coat collar, hunched up his shoulders, hid his hands in pockets, pulled the visor of his cap well forward over his eyes, and slouched past the fiacre.
Mrs. Hallam sat within. He could see her profile clearly silhouetted against the light; she was bending forward and staring fixedly out of the window, across the driveway. Mentally he calculated the direction of her gaze, then, moved away and followed it with his own eyes; and found himself staring at the façade of a third-rate hotel. Above its roof the gilded letters of a sign, catching the illumination from below, spelled out the title of "Hôtel du Commerce."
Mrs. Hallam was interested in the Hôtel du Commerce?
Thoughtfully Kirkwood fell back to his former point of observation, now the richer by another object of suspicion, the hostelry. Mrs. Hallam was waiting and watching for some one to enter or to leave that establishment. It seemed a reasonable inference to draw. Well, then, so was Kirkwood, no less than the lady; he deemed it quite conceivable that their objects were identical.
He started to beguile the time by wondering what she would do, if...
Of a sudden he abandoned this line of speculation, and catching his breath, held it, almost afraid to credit the truth that for once his anticipations were being realized under his very eyes.
Against the lighted doorway of the Hôtel du Commerce, the figures of two men were momentarily sketched, as they came hurriedly forth; and of the two, one was short and stout, and even at a distance seemed to bear himself with an accent of assertiveness, while the other was tall and heavy of shoulder.
Side by side they marched in step across the embankment to the head of the Quai gangway, descending without pause to the landing-stage. Kirkwood, hanging breathlessly over the guard-rail, could hear their footfalls ringing in hollow rhythm on the planks of the inclined way,—could even discern Calendar's unlovely profile in dim relief beneath one of the waterside lights; and he recognized unmistakably Mulready's deep voice, grumbling inarticulately.
