Anxious, as he was, to try his wits against some noted criminal, the chance had never been his to make the effort. He had indeed ferreted out one or two so-called "mysterious cases," but these had been in a small country village, where a victory over the dull-witted constabulary had counted for little in his own estimation.
Naturally he had read with avidity all the various newspaper accounts of the supposed murder of Mabel Sloane, and it was with considerable satisfaction that he had read the name upon the card intrusted to him to be taken to his employers. It seemed to him that at last fortune had placed an opportunity within his grasp. Here was a man, suspected of a great crime, whom the great Metropolitan detective force had entirely failed to locate. From what he had read of Dr. Medjora, he quickly decided that, though he might consult Messrs. Dudley & Bliss, he would not intrust them with his address. Jack Barnes determined to follow the Doctor when he should leave the office. Thus it was, that he was absent when Mr. Bliss inquired for him.
Descending by the elevator—a contrivance oddly named, since it takes one down as well as up,—he stationed himself in a secluded corner, whence he could keep watch upon the several exits from the building. Presently, he saw Dr. Medjora step from the elevator, and leave the building, after casting his eyes keenly about him, from which circumstance Barnes thought it best not to follow his man too closely. When, therefore, he saw the Doctor jump upon a Third Avenue horse-car, he contented himself with taking the next one following, and riding upon the front platform.
He saw nothing of Dr. Medjora until the Harlem terminus was reached. Here his man alighted and walked rapidly across the bridge over the river, Barnes following by the footpath on the opposite side, keeping the heavy timbers of the span between them as a screen. But, however careful Dr. Medjora had been to look behind him when leaving the lawyers' offices, he evidently felt secure now, for he cast no anxious glances backward. Thus Barnes shadowed him with comparative ease, several blocks uptown, and then down a cross street, until at last he disappeared in a house surrounded by many large trees.
Barnes stopped at the tumbled-down gate, which, swinging on one hinge, offered little hindrance to one who wished to enter. He looked at the house with curiosity. Old Colonial in architecture, it had evidently once been the summer home of wealthy folks. Now the sashless windows and rotting eaves marked it scarcely more than a habitat for crows or night owls. Wondering why Dr. Medjora should visit such a place, he was suddenly astonished to hear the sound of wheels rapidly approaching. Peeping back, he saw a stylish turn-out coming towards him, and it flashed across his mind that this might be the equipage in which the Doctor had been said to drive in the Park. Not wishing to be seen, he entered the grounds, ran quickly to the house, and admitted himself through a broken-down doorway that led to what had been the kitchen. He had scarcely concealed himself when the carriage stopped, a woman alighted, and walking up to the house, entered by the same door through which the Doctor had passed. Barnes was satisfied now that this meeting was pre-arranged, and that it would interest him greatly to overhear the conversation which would occur.
Seeking a means of reaching the upper floor, he soon found a stairway from which several steps were absent, but he readily ascended. At the top, he stopped to listen, and soon heard low voices still farther up. The staircase in the main hall was in a fair state of preservation, and there was even the remains of an old carpet. Carefully stepping, so as to avoid creaking boards, he soon reached a level from which he could peep into the room at the head of the stairs, and there he saw the two whom he was following. But though he could hear their voices, he could not distinguish their words. To do so he concluded that he must get into the adjoining room, but he could not go farther upstairs without being detected, as the door was open affording the Doctor a clear view of the top of the stairway.
Barnes formed his plan quickly. Reaching up with his hands, he took hold of the balustrade which ran along the hallway, and then, dangling in the air, he worked his way slowly from baluster to baluster, until he had passed the open doorway, and finally hung opposite the room which he wished to enter. Then he drew himself up, until he could rest a foot upon the floor of the hall, after which he quickly and noiselessly swung himself over and passed into the front room. That he succeeded, astonished him, after it had been done, for he could not but recognize that a single rotten baluster would either have precipitated him to the floor below, or at least by the noise of its breaking have attracted the attention of Dr. Medjora, who, be it remembered, was suspected of no less a crime than murder.
Looking about the room in which he then stood, he took little note of the decaying furniture, but went at once to a door which he thought must communicate with the adjoining room. Opening this very gently, he disclosed a narrow passageway, from which another door evidently opened into the room beyond. Stealthily he passed on, and pressing his ear against a wide crack, was pleased to find that he could easily hear what was said by the two in the next room. The conversation seemed to have reached the very point of greatest interest to him. The woman said:
"I wish to know exactly your connection with this Mabel Sloane."
"So do the police," replied the Doctor, succinctly.
