Now it will the other way be. Eh?"

"What do you want?" asked Nora, sharply.

"Do you so ask?" Bohlmier's tone was one of astonishment. "Is it possible? There is one supject only which we can talk about Is it not so? One supject. Yes?"

"I thought I told your friend all I had to say about that," said the girl.

"Ach! no! It is not true." If he had been able to see the old rascal, Scanlon was sure his head would be wagging and a mild smile would be upon his face. "You told him so--yes. But it is not true. Much more have you to say. Blenty more. And you will say it to me, eh? Now!"

The vision Bat had in his mind became more and more clear; not only would the bald head be moving from side to side, but it would be thrust forward in the deadly snake-like motion which the big athlete had seen once before. And the smile? He had never seen one like that which his ear told him Bohlmier's would be--a mild, quizzical smile which was a habit of the muscles only, and through which a pair of eyes gleamed with devilish purpose.

"Has he got me nervous, or something?" Bat asked himself. "Or do I call the turn on him right?"

"My friend," proceeded the old Swiss, "is a chentleman much ezberienced in certain things. In others he has not so much exberience as that," and the listener heard him snap his fingers, sharply. "Not so much as that!

And so he let you go without some understandings."

Bat heard Nora laugh. It was not a pleasant laugh; nevertheless it caused a thrill of pleasure to shoot through him.

"Good!" he thought. "She has her nerve with her. He hasn't scared her even a little bit."

"Perhaps," said Nora, to Bohlmier, "you have the experience he lacked?"

"I haf the handling of many affairs had," came the voice of the Swiss, smoothly. "And from the first I asked for this one; for I knew, dear lady, I could the resulds get."

"You mean you thought you could frighten me where he failed." Again Nora laughed. "You have confidence." Then with a note of curiosity in her voice: "What would you have done?"

A sudden sharp movement came from outside the rose arbor; Bat heard the hissing of Bohlmier's breath and a sharp cry from Nora. A diminished light ray, unseen in any other way, was caught upon the uplifted blade of a knife; then Bat drove his arms through the frail trellis work; with the left hand he gripped the arm of the Swiss and twisted it wickedly.

The knife was heard to strike against the side of the arbor as it fell.

Bat's right hand, at the same instant, slipped along the man's body and gripped his throat like iron; and as he held him, he heard the m.u.f.fled sound of Nora's steps as she fled away.

CHAPTER XX

QUEER INTELLIGENCE

The grip of Bat Scanlon upon the throat of Bohlmier did not relax; both hands of the Swiss clutched at the arm thrust through the trellis work of the rose arbor, but their puny strength was as nothing against the brawn of the big athlete. After a little the hands lost their power and slid helplessly away. Scanlon no longer heard the wheezing breath in the man's chest; and, so, he let go his grip. Bohlmier crumpled up and fell to the ground.

Bat drew his arms through the frail woodwork; there were many abrasions upon his knuckles and he was nursing these solicitously when he heard the stumbling approach of some one through the darkness. Instantly he was all attention; for a moment he fancied it was Nora returning; but the steps were not like hers--they were those of a man. Within a few yards of the rose arbor they stopped; there was a silence and then a voice said whisperingly:

"h.e.l.lo! Bohlmier, are you there?"

"Big Slim!" was Bat's mental exclamation. "Hunting up his pal."

As no reply came to the lank burglar's low call, that gentleman moved nearer; there was an awkward scrambling, a heavy body struck the side of the rose arbor and set it creaking; then the voice of Big Slim was heard uttering guarded but profane remarks.

"He's fallen over the Swiss," Bat told himself, grimly.

That this was true was proven in another moment. There came a long-drawn breath from the man outside as though he'd made a startling discovery; then Bat saw the glimmer of a light, faint and guarded, but enough to show the figure of the Swiss huddled on the ground, and with another stooping over it. The light suddenly snapped off; silence and darkness followed.

The silence was so long continued that Bat grew uneasy. He was anxious to once more get on the track of Nora; also he was not quite sure as to his own position.

"It was easy to see through this place just then," he thought. "That light must have shone in a little. My friend outside is a person of observation; so how do I know he hasn't spotted the fact that some one is here."

That the burglar could have recognized him, even if this were so, was impossible; for the light was too brief and too dim. But that he had caught sight of some one inside the arbor was within probability; so Bat stepped with great caution toward the doorway. As he reached it he saw, or perhaps felt, that there was a bulk directly before him, much denser than the darkness; and as he studied this it occurred to him that it was about the size of a man. But he was not at all sure; so he stood very still, all his thews flexed, and waited for it to move. In a few moments there came a slow stirring; the bulk seemed to push forward.

This was all Scanlon required; he lashed out with his right fist; it crashed into a living something with frightful force; there was a low outcry and a fall; and then Bat stepped out into the night and was away.

A score of paces from the rose arbor he stopped. He had not the least idea as to the direction Nora had taken, and so was puzzled about the next thing to do. But after the fright she had gotten he felt sure that she'd not linger about the little patch of ground surrounding No. 620 Duncan Street.

"She's away to the station," he said. "And that's my play."

So in a few moments he was on the street and hurrying toward the station. When within two score yards of it he heard a bell clang and caught the hiss of released steam. Then a train pulled out and rolled away down the dark line of track. The station lights were out, the platform was deserted and the waiting room, when he tried the door, was locked.

"Like as not she caught that train," mused Bat as he stood upon the platform. "And if so, all right."

He looked at a train schedule with the aid of a match, and then at his watch.

"Ten forty-eight," said he. "That's an hour yet. Some wait."

And a dismal, unproductive hour, too. The deserted platform, the chill winds and the drizzle of rain, made it most uncomfortable.

"I ought to be doing something," said he. "I ought to be----"

Of course! He ought to be at the Burton house; he ought to be trying to learn what was behind the marvel of the invalid girl who so suddenly became well; he ought to be eager and anxious to discover the objective of her cautious movements! At once, without any hesitancy, he hurried back along the way he had just come. Lights still burned brightly in comfortable little houses, set back from the street; they glowed with cheer and family life; but on the way he did not encounter a single pedestrian.

"Stanwick is strictly an indoor place on a rainy Sunday night," he mused, as he hurried along. "And I don't know that it hasn't the best of it."

He was inside the iron fence at No. 620 when he detected the first signs of a stir; these were the low sounds of careful steps on the walk and the murmur of conversation. He crouched in the shadow thrown by the house; the steps grew nearer and he recognized the voices as those of Big Slim and Bohlmier.

"I haf not much strength," wheezed the Swiss. "Holt me up! Ach! what a grip! It was like a gorilla's!"

As they drew opposite to Bat, he saw in an uncertain sort of way that the burglar was supporting his friend.

"Grip!" said Big Slim. "Well, the wallop he carried had some heft, too.

Once I thought I had him; he stood right in front of me; but as I was reaching for my 'gat' he drove one at me that a bull couldn't have stood up under."

"That woman!" gasped Bohlmier, "she is full of tricks, yet. Who would haf thought she had somebodies here with her."

What the burglar replied Bat could not catch, for by this time they had reached the sidewalk. Under the light he saw the Swiss was holding to the other feebly, and that his steps were tottering and weak.

"I must have shut down on him even harder than I thought," said Bat to himself. "It was the knife that did it, and him whipping it out on Nora."

He waited until the two had disappeared; then he made his way softly around the house on the side he had not examined before. Here the windows were all blank and dark except one at the extreme rear. There he could see the colored maid washing some gla.s.sware; this window was partly open and he heard the woman's voice singing:

"Swing low, sweet chariot, Come fo' to carry me home."

Bat stood for a while in silent inspection of the place.
