Some of these latter might have been surprised, and possibly a little fluttered, one evening, at seeing a well-dressed young gentleman standing at the gate as they came forth, gazing with languid interest from one face to another, as if he were on the look-out for some one of their number.
But they would have been yet more astonished could they have seen him still lingering after the last one had passed, watching with unabated patience the opening and shutting of the small side door devoted to the use of the firm, and such employés as had seats in the office. It was Mr. Byrd, and his purpose there at this time of day was to see and review the whole rank and file of the young men employed in the place, in the hope of being able to identify the nephew of Mrs. Clemmens by his supposed resemblance to the person whose character of face and form had been so minutely described to him.
For Mr. Byrd was a just man and a thoughtful one, and knowing this identification to be the key-stone of his lately formed theory, desired it to be complete and of no doubtful character. He accordingly held fast to his position, watching and waiting, seemingly in vain, for the dark, powerful face and the sturdily-built frame of the gentleman whose likeness he had attempted to draw in conjunction with that of Miss Dare. But, though he saw many men of all sorts and kinds issue from one door or another of this vast building, not one of them struck him with that sudden and unmistakable sense of familiarity which he had a right to expect, and he was just beginning to doubt if the whole framework of his elaborately-formed theory was not destined to fall into ruins, when the small door, already alluded to, opened once more, and a couple of gentlemen came out.
The appearance of one of them gave Mr. Byrd a start. He was young, powerfully built, wore a large mustache, and had a complexion of unusual swarthiness. There was character, too, in his face, though not so much as Mr. Byrd had expected to see in the nephew of Mrs. Clemmens. Still, people differ about degrees of expression, and to his informant this face might have appeared strong. He was dressed in a business suit, and was without an overcoat—two facts that made it difficult for Mr. Byrd to get any assistance from the cut and color of his clothes.
But there was enough in the general style and bearing of this person to make Mr. Byrd anxious to know his name. He, therefore, took it upon himself to follow him—a proceeding which brought him to the corner just in time to see the two gentlemen separate, and the especial one in whom he was interested, step into a car.
He succeeded in getting a seat in the same car, and for some blocks had the pleasure of watching the back of the supposed Mansell, as he stood on the front platform with the driver. Then others got in, and the detective's view was obstructed, and presently—he never could tell how it was—he lost track of the person he was shadowing, and when the chance came for another sight of the driver and platform, the young man was gone.
Annoyed beyond expression, Mr. Byrd went to a hotel, and next day sent to the mill and procured the address of Mr. Mansell. Going to the place named, he found it to be a very respectable boarding-house, and, chancing upon a time when more or less of the rooms were empty, succeeded in procuring for himself an apartment there.
So here he was a fixture in the house supposed by him to hold the murderer of Mrs. Clemmens. When the time for dinner came, and with it an opportunity for settling the vexed question of Mr. Mansell's identity not only with the man in the Syracuse depot, but with the person who had eluded his pursuit the day before, something of the excitement of the hunter in view of his game seized upon this hitherto imperturbable detective, and it was with difficulty he could sustain his usual rôle of fashionable indifference.
He arrived at the table before any of the other boarders, and presently a goodly array of amiable matrons, old and young gentlemen, and pretty girls came filing into the room, and finally—yes, finally—the gentleman whom he had followed from the mill the day before, and whom he now had no hesitation in fixing upon as Mr. Mansell.
But the satisfaction occasioned by the settlement of this perplexing question was dampened somewhat by a sudden and uneasy sense of being himself at a disadvantage. Why he should feel thus he did not know. Perhaps the almost imperceptible change which took place in that gentleman's face as their eyes first met, may have caused the unlooked-for sensation; though why Mr. Mansell should change at the sight of one who must have been a perfect stranger to him, was more than Mr. Byrd could understand. It was enough that the latter felt he had made a mistake in not having donned a disguise before entering this house, and that, oppressed by the idea, he withdrew his attention from the man he had come to watch, and fixed it upon more immediate and personal matters.
