The Silent Bullet Part 42

Almost gaily Kennedy swung along toward Broadway. At the corner he hesitated, glanced up and down, caught sight of the furniture-van in the middle of the next block. The driver was tugging at the harness of the horses, apparently fixing it. We walked along and stopped beside it.

"Drive around in front of the Vesper Club slowly," said Kennedy as the driver at last looked up.

The van lumbered ahead, and we followed it casually. Around the corner it turned. We turned also. My heart was going like a sledgehammer as the critical moment approached. My head was in a whirl. What would that gay throng back of those darkened windows down the street think if they knew what was being prepared for them?

On, like the Trojan horse, the van lumbered. A man went into the Vesper Club, and I saw the negro at the door eye the oncoming van suspiciously.

The door banged shut.

The next thing I knew, Kennedy had ripped off his disguise, had flung himself up behind the van, and had swung the doors open. A dozen men with ages and sledge-hammers swarmed out and up the steps of the club.

"Call the reserves, O'Connor," cried Kennedy. "Watch the roof and the back yard."

The driver of the van hastened to send in the call.

The sharp raps of the hammers and the axes sounded on the thick bra.s.s-bound oak of the outside door in quick succession. There was a scurry of feet inside, and we could hear a grating noise and a terrific jar as the inner, steel door shut.

"A raid! A raid on the Vesper Club!" shouted a belated pa.s.ser-by.

The crowd swarmed around from Broadway, as if it were noon instead of midnight.

Banging and ripping and tearing, the outer door was slowly forced. As it crashed in, the quick gongs of several police patrols sounded. The reserves had been called out at the proper moment, too late for them to "tip off" the club that there was going to be a raid, as frequently occurs.

Disregarding the melee behind me, I leaped through the wreckage with the other raiders. The steel door barred all further progress with its cold blue impa.s.sibility. How were we to surmount this last and most formidable barrier?

I turned in time to see Kennedy and O'Connor hurrying up the steps with a huge tank studded with bolts like a boiler, while two other men carried a second tank.

"There," ordered Craig, "set the oxygen there," as he placed his own tank on the opposite side:

Out of the tanks stout tubes led, with stopc.o.c.ks and gages at the top.

From a case under his arm Kennedy produced a curious arrangement like a huge hook, with a curved neck and a sharp beak. Really it consisted of two metal tubes which ran into a sort of cylinder, or mixing chamber, above the nozzle, while parallel to them ran a third separate tube with a second nozzle of its own. Quickly he joined the ends of the tubes from the tanks to the metal hook, the oxygen-tank being joined to two of the tubes of the hook, and the second tank being joined to the other. With a match he touched the nozzle gingerly. Instantly a hissing, spitting noise followed, and an intense blinding needle of flame.

"Now for the oxy-acetylene blowpipe," cried Kennedy as he advanced toward the steel door. "We'll make short work of this."

Almost as he said it, the steel beneath the blowpipe became incandescent.

Just to test it, he cut off the head of a three-quarter-inch steel rivet--taking about a quarter of a minute to do it. It was evident, though, that that would not weaken the door appreciably, even if the rivets were all driven through. Still they gave a starting-point for the flame of the high-pressure acetylene torch.

It was a brilliant sight. The terrific heat from the first nozzle caused the metal to glow under the torch as if in an open-hearth furnace. From the second nozzle issued a stream of oxygen under which the hot metal of the door was completely consumed. The force of the blast as the compressed oxygen and acetylene were expelled carried a fine spray of the disintegrated metal visibly before it. And yet it was not a big hole that it made--scarcely an eighth of an inch wide, but clear and sharp as if a buzz-saw were eating its way through a three-inch plank of white pine.

With tense muscles Kennedy held this terrific engine of destruction and moved it as easily as if it had been a mere pencil of light. He was easily the calmest of us all as we crowded about him at a respectful distance.

"Acetylene, as you may know," he hastily explained, never pausing for a moment in his work, "is composed of carbon and hydrogen. As it burns at the end of the nozzle it is broken into carbon and hydrogen--the carbon gives the high temperature, and the hydrogen forms a cone that protects the end of the blowpipe from being itself burnt up."

"But isn't it dangerous?" I asked, amazed at the skill with which he handled the blowpipe.

"Not particularly--when you know how to do it. In that tank is a porous asbestos packing saturated with acetone, under pressure. Thus I can carry acetylene safely, for it is dissolved, and the possibility of explosion is minimised. This mixing chamber by which I am holding the torch, where the oxygen and acetylene mix, is also designed in such a way as to prevent a flash-back. The best thing about this style of blowpipe is the ease with which it can be transported and the curious uses--like the present--to which it can be put."

He paused a moment to test the door. All was silence on the other side.

The door itself was as firm as ever.

"Huh!" exclaimed one of the detectives behind me, "these new-fangled things ain't all they're cracked up to be. Now if I was runnin' this show, I'd dynamite that door to kingdom come."

"And wreck the house and kill a few people," I returned, hotly resenting the criticism of Kennedy. Kennedy affected not to hear.

"When I shut off the oxygen in this second jet," he resumed as if nothing had been said, "you see the torch merely heats the steel. I can get a heat of approximately sixty-three hundred degrees Fahrenheit, and the flame will exert a pressure of fifty pounds to the square inch."

"Wonderful!" exclaimed O'Connor, who had not heard the remark of his subordinate and was watching with undisguised admiration. "Kennedy, how did you ever think of such a thing?"

"Why, it's used for welding, you know," answered Craig as he continued to work calmly in the growing excitement: "I first saw it in actual use in mending a cracked cylinder in an automobile. The cylinder was repaired without being taken out at all. I've seen it weld new teeth and build up old worn teeth on gearing, as good as new."

He paused to let us see the terrifically heated metal under the flame.

"You remember when we were talking on the drive about the raid, O'Connor? A car-load of sc.r.a.p-iron went by on the railroad below us.

They use this blowpipe to cut it up, frequently. That's what gave me the idea. See. I turn on the oxygen now in this second nozzle. The blowpipe is no longer an instrument for joining metals together, but for cutting them asunder. The steel burns just as you, perhaps, have seen a watch-spring burn in a jar of oxygen. Steel, hard or soft, tempered, annealed, chrome, or Harveyised, it all burns just as fast and just as easily. And it's cheap too. This raid may cost a couple of dollars, as far as the blowpipe is concerned--quite a difference from the thousands of dollars' loss that would follow an attempt to blow the door in."

The last remark was directed quietly at the doubting detective. He had nothing to say. We stood in awe-struck amazement as the torch slowly, inexorably, traced a thin line along the edge of the door.

Minute after minute sped by, as the line burned by the blowpipe cut straight from top to bottom. It seemed hours to me. Was Kennedy going to slit the whole door and let it fall in with a crash?

No, I could see that even in his cursory examination of the door he had gained a pretty good knowledge of the location of the bolts imbedded in the steel. One after another he was cutting clear through and severing them, as if with a superhuman knife.

What was going on on the other side of the door, I wondered. I could scarcely imagine the consternation of the gamblers caught in their own trap.

With a quick motion Kennedy turned off the acetylene and oxygen. The last bolt had been severed. A gentle push of the hand, and he swung the once impregnable door on its delicately poised hinges as easily as if he had merely said, "Open Sesame." The robbers' cave yawned before us.

We made a rush up the stairs. Kennedy was first, O'Connor next, and myself scarcely a step behind, with the rest of O'Connor's men at our heels.

I think we were all prepared for some sort of gun-play, for the crooks were desperate characters, and I myself was surprised to encounter nothing but physical force, which was quickly, overcome.

In the now disordered richness of the rooms, waving his "John Doe"

warrants in one hand and his pistol in the other, O'Connor shouted "you're all under arrest, gentlemen. If you resist further it will go hard with you."

Crowded now in one end of the room in speechless amazement was the late gay party of gamblers, including Senator Danfield himself. They had reckoned on toying with any chance but this. The pale white face of DeLong among them was like a spectre, as he stood staring blankly about and still insanely twisting the roulette wheel before him.

Kennedy advanced toward the table with an ax which he had seized from one of our men. A well-directed blow shattered the mechanism of the delicate wheel.

"DeLong," he said, "I'm not going to talk to you like your old professor at the university, nor like your recent friend, the Frenchman with a system. This is what you have been up against, my boy. Look."

His forefinger indicated an ingenious, but now tangled and twisted, series of minute wires and electro-magnets in the broken wheel before us. Delicate brushes led the current into the wheel. With another blow of his axe, Craig disclosed wires running down through the leg of the table to the floor and under the carpet to b.u.t.tons operated by the man who ran the game.

"Wh--what does it mean?" asked DeLong blankly.

"It means that you had little enough chance to win at a straight game of roulette. But the wheel is very rarely straight, even with all the odds in favour of the bank, as they are. This game was electrically controlled. Others are mechanically controlled by what is sometimes called the 'mule's ear,' and other devices. You can't win. These wires and magnets can be made to attract the little ball into any pocket the operator desires. Each one of those pockets contains a little electro-magnet. One set of magnets in the red pockets is connected with one b.u.t.ton under the carpet and a battery. The other set in the black pockets is connected with another b.u.t.ton and the battery. This ball is not really of platinum. Platinum is nonmagnetic. It is simply a soft iron hollow ball, plated with platinum. Whichever set of electro-magnets is energised attracts the ball and by this simple method it is in the power of the operator to let the ball go to red or black as he may wish. Other similar arrangements control the odd or even, and other combinations from other push b.u.t.tons. A special arrangement took care of that '17' freak. There isn't an honest gambling-machine in the whole place--I might almost say the whole city. The whole thing is crooked from start to finish--the men, the machines, the--"

"That machine could be made to beat me by turning up a run of '17' any number of times, or red or black, or odd or even, over '18' or under '18,' or anything?"

"Anything, DeLong."

"And I never had a chance," he repeated, meditatively fingering the wires. "They broke me to-night. Danfield"--DeLong turned, looking dazedly about in the crowd for his former friend, then his hand shot into his pocket, and a little ivory-handled pistol flashed out--"Danfield, your blood is on your own head. You have ruined me."
