"Then they turned in this direction. The railroads are over there. Yes, that is what they would make for. Dillon," he called, "let us follow the right bank of the river down this way, and see if we can't pick them up again."

The river was shallow at this point, but full of rocks, which made it extremely hard, if not dangerous, to walk even close to the bank in the darkness. "I don't think they'd stand for much of this sort of going,"

remarked Garrick. "A little of it would satisfy them, and they'd strike out again."

He was right. Perhaps five minutes later, after wading in the cold water, clinging as close to the bank as we could, we came to a sort of rapids. Cherry, who had been urged on by Dillon, gave a jerk at her leash, as she sniffed along the bank.

"She has it," cried Garrick, springing up the bank after Dillon.

I followed and we three men and three dogs struck out again in earnest across country.

We had come upon a long stretch of woods, and the brambles and thick growth made the going exceedingly difficult. Still, if it was hard for us now, it must have been equally hard for them as they broke through in the first place.

At last we came to the end of the woods. The trail was now fresher than ever, and Dillon had difficulty in holding Cherry back so that the rest of us could follow. As we emerged from the shadow of the trees into the open field, it seemed as if guns were blazing on all sides of us.

We were almost up with them. They had separated and were not half a mile away, firing at random in our direction, as they heard the dogs.

Dillon drew up, Cherry tugging ahead. He turned to the Airedales. They had already taken in the situation, and were now darting ahead at what they could see, if not scent.

I felt a "ping!" on my chest. I scarcely realized what it was until I heard something drop the next instant in the stubble at my feet, and felt a smarting sensation as if a sharp blow had struck me. I bent down and from the stubble picked up a distorted bullet.

"These bullet-proof coats are some good, anyhow, at a distance,"

remarked Garrick, close beside me, as he took the bullet from my fingers. "Duck! Back among the trees--until we get our bearings!"

Another bullet had whizzed just past his arm as he spoke.

We dodged back among the trees, and slowly skirted the edge of the wood, where it bent around a little on the flank of the position from which the continuous firing was coming.

At the edge we stopped again. We could go no further without coming out into the open, and the moon, just rising, above the trees, made us an excellent mark under such conditions. Garrick peered out to determine from just where they were firing.

"Lucky for us that we had these coats," he muttered, "or they would have croaked us, before we knew it. These are our old friends, the anaesthetic bullets, too. Even a little scratch from one of them and we should be hors de combat for an hour or two."

"Shall we take a chance?" urged Dillon.

"Just a minute," cautioned Garrick, listening.

The barking of the Airedales had ceased suddenly. Cherry was straining at her leash to go.

"They have winged the two dogs," exclaimed Garrick. "Yes--we must try it now--at any cost."

We broke from the cover, taking a chance, separating as much as we could, and pushing ahead rapidly, Dillon under his breath keeping Cherry from baying as much as possible.

I had expected a sharp fusillade to greet us as we advanced and wondered whether the coats would stand it at closer range. Instead, the firing seemed to have ceased altogether.

A quick dash and we had crossed the stretch of open field that separated us from a dark object which now loomed up, and from behind which it seemed had come the firing. As we approached, I saw it was a shed beside the railroad, which was depressed at this point some twelve or fifteen feet.

"They kept us off just long enough," exclaimed Garrick, glancing up at the lights of the block signals down the road. "They must be desperate, all right. Why, they must have jumped a freight as it slowed down for the curve, or perhaps one of them flagged it and held it up. See? The red signal shows that a train has just gone through toward New York.

There is no chance to wire ahead, either, from this Ducktown siding.

Here's where they stood--look!"

Garrick had picked up a handful of exploded cartridge sh.e.l.ls, while he was speaking. They told a mute story of the last desperate stand of the gunmen.

"I'll keep these," he said, shoving them into his pocket. "They may be of some use later on in connecting to-night's doings with what has gone before."

We looked at each other blankly. There was nothing more to do that night but to return to the now deserted house in the valley where we had left Forbes in charge of Dillon's man.

Toilsomely and disgusted, we trudged back in silence.

Garrick, however, refused to be discouraged. Late as it was, he insisted on making a thorough search of the captured house. It proved to be a veritable a.r.s.enal. Here it seemed that all the new and deadly weapons of the scientific gunman had been made. The barn, turned into half garage and half workshop, was a mine of interest.

We found it unlocked and entered, Garrick flashing a light about.

"There's a sight that would do McBirney's eyes good," he exclaimed as he bent the rays of the light before us.

Before us, in the back of the barn, stood Warrington's stolen car--at last.

"They won't plot anything more--at least not up here," remarked Garrick, bending over it.

In the house, we found Jim still with Forbes, who was now completely recovered. In the possession of his senses, Forbes' tongue which the anaesthetic gases seemed to have loosened, now became suddenly silent again. But he stuck doggedly to his story of kidnapping, although he would not or could not add anything to it. Who the kidnapper was he swore he did not know, except that he had known his face well, by sight, at the gambling joint.

I could make nothing of Forbes. But of one thing I was sure. Even if we had not captured the scientific gunman, we had dealt him a severe and crushing blow. Like Garrick, I had begun to look upon the escape philosophically.

CHAPTER XXIV

THE FRAME-UP

Although I felt discouraged on our return to the city, the morning following our exciting adventure at the mysterious house in the Ramapo valley, Garrick, who never let anything ruffle him long, seemed quite cheerful.

"Cheer up, Tom," he encouraged. "We are on the home stretch now."

"Perhaps--if they don't beat us to the tape," I answered disconsolately. "What are you going to do next?"

"While you were s.n.a.t.c.hing a little sleep, I was rummaging around and found a number of letters in a table drawer, up there. One was a note, evidently to the garage keeper, and signed merely, 'Chief.' I'll wager that the handwriting is the same as that in the blackmailing letter to Miss Winslow."

"What of it?" I asked, refusing to be comforted. "We haven't got him and the prospects--"

"No, we haven't got him," interrupted Garrick, "but the note was just a line to tell the Boss, who seemed to have been up there in the country at the time, to meet the Chief at 'the Joint,' on Second Avenue."

I nodded, but before I could speak, he added, "It didn't say any more, but I think I know the place. It is the old International Cafe, a regular hang-out for crooks, where they come to gamble away the proceeds of their crimes in stuss, the great game of the East Side, now. Anyhow, we'll just drop into the place. We may not find them, but we'll have an interesting time. Then, there is the possibility of getting a strangle hold on someone, anyhow."

Garrick was evidently figuring on having driven our gunman back into the haunts of the underworld.

There seemed to be no other course that presented itself and therefore, rather than remain inactive until something new turned up, I consented to accompany him in his excursion.

Forbes, still uncommunicatively protesting that he would say nothing until he had an opportunity to consult a lawyer, had been taken down to New York by Dillon during the morning and was lodged in a West Side prison under a technical charge which was sufficient to hold him until Garrick could investigate his case and fix his real status.

We had taken a cross-town car, with the intention of looking over the dive where Garrick believed the crooks might drop in. The ride itself was uninteresting, but not so by any means the objective point of our journey.
