This guess proved a good one; the huge pile of the station soon loomed into view, the lights about its top dimming in the mists of the evening, the great round clock looking solemnly out across the city. Bat saw the two men follow into the building; he at once stationed himself at a door, through the gla.s.s of which he had a view of the ticket window.

Nora went, without hesitation, to a certain window far down the room; in a few moments she turned away, a ticket in her hand and her eyes going to the clock. And as she disappeared up the stairs which led to the train shed, Bohlmier and Big Slim slipped up to the window, purchased tickets and followed her. When they were out of sight, Bat entered and walked down the huge room. Over the window to which the others had gone he saw a sign which told him the tickets for sale there were for the branch road upon which lay the suburb of Stanwick. Bat also bought a ticket.

In the train shed a light over a gate called his attention to the three cars which usually made up the local for the western suburbs. Nora was not in sight; the Swiss and Big Slim were climbing into a dingy combination baggage and smoking car which was directly behind the engine.

"I don't want to get into the car Nora's in," mused Bat. "And as she's an experienced traveler, I'd say that was the middle one."

He entered the last car by the rear door; a glance showed him that Nora was not there; and he settled himself in a corner seat opening a newspaper and holding it before him so as to avoid even the small chances of detection. In a few minutes the train started and in half an hour it brought up at Stanwick. From his window he saw Nora on the platform. His first impulse was to get out on the other side of the train, but instantly he realized that he must not do this.

"It's the very thing those other two gentlemen will do; and they'd spot me sure," he thought.

So he waited until the last possible moment; he dropped from the car as the train was pulling out, and a heaped up baggage truck hid him from view. He saw Bohlmier and Big Slim pa.s.s cautiously along the length of the platform, and out of sight; and then pursuers and pursued made away in the direction of Duncan Street.

"It's getting to be familiar ground," said the big athlete; "I think I could find my way there with my eyes shut."

The streets of Stanwick were lighted here and there by incandescent lights which shone yellowly through the heavy darkness. Bat could not be sure as to what was going on ahead of him, as the two men were careful to keep out of the rays of the lamps as they pa.s.sed them. So he proceeded slowly with only occasional glimpses of the moving figures.

Finally, as he neared the Burton home, he lost them entirely.

"They've taken cover," said he, between his teeth. "And now I'll have to trust to chance."

Keeping in the darkness as much as possible, he advanced; and in a little while he saw a m.u.f.fled figure standing before a gate as though hesitating. It was Nora, and the house before which she had halted was No. 620. However, the hesitancy did not last long; for as he watched, she pushed open the gate and made her way toward the house.

Scanlon waited, his eyes going about in expectation of a movement of some sort from the shadows around him. But none came, and he gave his attention once more to Nora. He saw her move along the path as though to the door, over which burned a light; however, when within a half dozen yards of it, she veered to one side, and, to Bat's surprise, stole with quiet tread around the house.

CHAPTER XIX

IN THE DARK

As Bat Scanlon saw Nora disappear around the Burton house he once more awaited some developments from the shadows; but again there was no sign of the presence of either the Swiss or the lank burglar. So after a little he moved on until he reached the gate of the adjoining house and quietly lifted the latch.

A dog, from somewhere in the darkness, barked; Bat halted and listened, but there were no further sounds, and so he went on. Placing his hands upon the low division fence he bounded over upon the Burton lawn. Almost directly before him was the rose arbor behind which Ashton-Kirk had discovered the woman's footprints; and the big athlete took his place in the deep shadow of this and looked about. The window of the Burton sitting-room was lighted; inside was Mary Burton in her reclining chair, propped up by pillows, and reading. The shaded lamp cast a soft glow upon her; the white face wore an expression of suffering, and with this was a meekness, a submission which made it nun-like.

A woman's form flitted between Scanlon and the window; it stopped, and then the watcher saw Nora Cavanaugh peering in at the sick girl.

"Her notions of a social call seem to have picked up a twist somewhere,"

said Bat, to himself. "What's the idea?"

However, Nora only remained at the window for a few moments; then she disappeared in the direction from which she had come. In Bat's mind was a picture of two lurking men, the lank desperado, and the mild looking, yet murderous, Swiss; and he felt a chill of fear as he gazed into the darkness which had swallowed the girl up. A moment or two pa.s.sed, then he heard the quick br-r-r-r! of an electric bell from the house.

"The door-bell," said Bat. "Through the sound of a hundred others I'd match myself to pick the one attached to the door of any house. They are all of the same family."

Another little pause; then he saw Nora in the sitting-room, the nurse behind her, and the sick girl reaching out her hand gladly. Bat breathed a sigh of relief.

"All right," said he. "Inside, she's not so likely to meet those gentlemen."

The nurse disappeared from the sitting-room; Nora sat down and began to talk with the invalid, earnestly. Outside all was still; after a little, Bat searched the surrounding shadows intently for anything that might indicate the whereabouts of Big Slim and Bohlmier; but the darkness was silent and complete. The windows of the houses opposite and adjoining were lighted; from one some little distance away came the faint tinkling of a mandolin, and the deeper sounding strings of a guitar; from still another came fresh young voices singing an evening hymn. Figures could be seen through the windows or silhouetted upon the shades; at one Bat saw a tiny girl and a very large dog who seemed her especial chum; they romped gaily; Bat heard the child laugh and the dog bark.

"Nice," he mused. "Nice and homey. Regular Sunday night stuff in the bosom of the family. But no sign of the two gentlemen who did the shadowing. They are lying low, I guess, same as I am."

He gave his attention once more to the sitting-room; Nora and the sick girl were still engaged in conversation. As Bat looked, Nora took a crumpled newspaper page from her hand-bag, as though it were a part of what she was telling. The girl in the chair lifted herself up, eagerly, took the paper in her hand and read the staring head-lines. Then Bat saw it flutter to the floor, he saw her sit upright for a moment, gazing at Nora with wide-opened eyes; she sank back suddenly and heavily upon the cushions.

"Fainted!" said Bat, excitedly, leaning forward. He saw Nora arise quickly and bend over the girl, then he saw her open the door. "Calling the nurse," said he.

In a moment the nurse was in the room; and under the care of the two the invalid was soon restored to consciousness. Then followed a period of comforting, of patting pillows into shape, of cheerful a.s.surance. Nora then kissed the invalid and bid her good-bye. She left the room with the nurse following her.

"Just came, evidently, to give her the news," said Bat to himself. "But I wonder why the haste. It wasn't the kind of news that would give joy or anything like that."

In a few moments he heard the front door close, and steps upon the walk.

These ceased after a moment; there was silence; and then, to his amazement, Nora once more flitted through the darkness and came between himself and the window.

"There is a reason for it," said Bat. "She's not doing all this out of just idle curiosity. But what it leads to is a thing I don't----"

The thought was halted, unfinished, in his mind; for through the darkness, quite close at hand, came a cautiously moving shape; and from its direction, it was also seeking the shelter of the rose arbor. There was a door in the far side of the latter, as Bat had noticed on the day of Ashton-Kirk's investigation; he slipped quietly around and in at this; and through the trellis work he watched what was proceeding outside. The first glance showed him that Nora was now, also, moving toward the arbor, and the thought of what might occur upon her meeting with the prowler in the dark caused Scanlon's hand to go inquiringly to the big revolver which he carried in the breast pocket of his coat, and to shift it to a place where it would be more convenient.

But, though he strained his eyes to catch some indications of the shadowy figure he had seen only a moment or two before, he could not do so; it had vanished. This did not add anything to the big athlete's quietude of mind; for the footsteps of Nora, dulled by springy sod, were now close at hand.

The girl reached the arbor and took up the position which Bat had lately occupied; and he knew that she had settled herself for a vigil--to watch all that pa.s.sed in the sitting-room of the Burton house. Naturally, the eyes of the big man also went in that direction once more.

The nurse had returned to the room and was bending over the invalid, a gla.s.s in her hand. The girl lay motionless, her face turned upward and her thin hands pathetically folded. The nurse, after she had succeeded in inducing the patient to take a few drops of what she held to her lips, busied herself with some things upon a small table near the chair; then she left the room.

There was a pause; no movement came from the room whatsoever. Bat fancied that the sick girl had gone to sleep; but this thought had no sooner taken shape in his mind than he saw her stir. Then she arose slowly in the chair, and sat, apparently listening, her manner surprisingly alert. Only a few moments ago she had shown every sign of exhaustion; now her strength was unquestioned, for her body was firmly held and her grip upon the arms of the chair was sure.

There came a little gasp from Nora crouching behind the rose arbor.

"Surprised!" thought Bat. "And no wonder! I'm just a little bit that way myself."

Mary Burton threw back the blanket in which she was swathed, and stood up. She wore a long dressing gown, tied about the waist; from a pocket of this she took something, and then after a moment of listening approached an old mahogany high-boy, unlocked and opened a drawer and looked into it. Almost at once it was slid back into place and relocked; the girl stood poised for an instant, as though not sure as to what her next movement would be; then she went tiptoeing to the door, opened it, and disappeared.

Nora drew a long breath; and Scanlon, as he stood, amazed, felt like echoing it. But the next instant all that which had happened in the sitting-room, surprising as it had been, was wiped from his mind. From outside there came a low-pitched voice, that of old Bohlmier:

"Do not make some noise!" it said. A gasp came from Nora, a gasp which would have been a scream if fear had not suppressed it. "I will talk a little with you, if you blease."

There was an instant's silence; Bat pressed hard against the trellis work of the arbor--only a few inches separated him from the girl outside, and he could hear her breath catching sharply in her throat as she spoke.

"Who are you?"

"We will nod speak of that," said the Swiss. "Only we will talk of things that interesting are."

This seemed to have a tonic effect upon Nora; when she answered her breathing had become almost normal; her voice was strong and held some confidence.

"I know you now," she said. "I saw you the other night."

Old Bohlmier chuckled.

"Ach! yes, the other night. You saw me, yes, but you spoke to me not!
