"See!" exclaimed Kennedy, triumphantly, working rapidly. "Take the word 'war' for instance. The square which contains WA is in line S, column D. So I put down SD. The odd letter R, with a dash, is in line R, column Y. So I put down RY. WAR thus becomes SDRY. Working it backward from SDRY, I take the two letters SD. In line S, column D, I find WA in the square, and in line R, column Y, I find just R--making the translation of the cipher read 'War.' Now," he went on, excitedly, "take the message we have:

"SOWC FSSJWA EKNLFFBY WOVHLX IHWAJYKH 101MLEL EPJNVPSL WCLURL GHIHDA ELBA.

"I translate each pair of letters as I come to them." He was writing rapidly. There was the message:

Have located New York headquarters at 101 Eveningside Avenue, Apartment K. Kennedy did not pause, but dashed from the room, followed by Grady and myself.

As our taxi pulled up on the avenue, we saw that the address was a new but small apartment-house. We entered and located Apartment K.

Casting about for a way to get in, Craig discovered that the fire-escape could be reached from a balcony by the hall window. He swung himself over the gap, and we followed. It was the work of only a minute to force the window-latch. We entered. No one was there.

As we pressed after him, he stopped short and flashed his electric bull's-eye about with an exclamation of startled surprise. There was a fully equipped chemical and electrical laboratory. There were explosives enough to have blown not only us but a whole block to kingdom come. More than that, it was a veritable den of poisons. On a table stood beakers and test-tubes in which was crushed a paste that still showed parts of the red ruttee beans.

"Some one planned here to kill Shirley, get him out of the way,"

reconstructed Kennedy, gazing about; "some one working under the cloak of Oriental religion."

"Mrs. Anthony?" queried Grady. Kennedy shook his head.

"On the contrary, like Shirley, she was an agent of the Indian Secret Service. The rest of the cipher shows it. She was sent to watch some one else, as he was sent to watch Mrs. Rogers. Neither could have known that the other was on the case. She found out, first, that the package with the prayer-bean and the word 'Gadhr' was an attempt to warn and save Shirley, whom she had known in Calcutta and still loved, but feared to compromise. She must have tried to see him, but failed. She hesitated to write, but finally did. Then some one must have seen that she was dangerous. Another poisoned bomb was sent to her. No; the nautch-girl is innocent."

"'Sh!" cautioned Grady.

Outside we could hear the footsteps of some one coming along the hall.

Kennedy snapped off his light. The door opened.

"Stand still! One motion and I will throw it!"

As Kennedy's voice rang out from the direction of the table on which stood the half-finished gla.s.s bombs, Grady and I flung ourselves forward at the intruder, not knowing what we would encounter.

A moment later Kennedy had found the electric switch and flashed up the lights.

It was Singh, who had used both Mrs. Rogers's money and Raimanandra's religion to cover his conspiracy of revolt.

V

THE PHANTOM DESTROYER

"Guy Fawkes himself would shudder in that mill. Think of it--five explosions on five successive days, and not a clue!"

Our visitor had presented a card bearing the name of Donald MacLeod, chief of the Nitropolis Powder Company's Secret Service. It was plain that he was greatly worried over the case about which he had at last been forced to consult Kennedy.

As he spoke, I remembered having read in the despatches about the explosions, but the accounts had been so meager that I had not realized that there was anything especially unusual about them, for it was at the time when accidents in and attacks on the munitions-plants were of common occurrence.

"Why," went on MacLeod, "the whole business is as mysterious as if there were some phantom destroyer at work! The men are so frightened that they threaten to quit. Several have been killed. There's something strange about that, too. There are ugly rumors of poisonous gases being responsible, quite as much as the explosions, though, so far, I've been able to find nothing in that notion."

"What sort of place is it?" asked Kennedy, interested at once.

"Well, you see," explained MacLeod, "since the company's business has increased so fast lately, it has been forced to erect a new plant.

Perhaps you have heard of the Old Grove Amus.e.m.e.nt Park, which failed?

It's not far from that."

MacLeod looked at us inquiringly, and Kennedy nodded to go on, though I am sure neither of us was familiar with the place.

"They've called the new plant Nitropolis--rather a neat name for a powder-works, don't you think?" resumed MacLeod. "Everything went along all right until a few days ago. Then one of the buildings, a storehouse, was blown up. We couldn't be sure that it was an accident, so we redoubled our precautions. It was of no use. That started it. The very next day another building was blown up, then another, until now there have been five of them. What may happen to-day Heaven only knows!

I want to get back as soon as I can."

"Rather too frequent, I must admit, to be coincidences," remarked Kennedy.

"No; they can't all be accidents," a.s.serted MacLeod, confidently.

"There's too great regularity for that. I think I've considered almost everything. I don't see how they can be from bombs placed by workmen.

At least, it's not a bit likely. Besides, the explosions all occur in broad daylight, not at night. We're very careful about the men we employ, and they're watched all the time. The company has a guard of its own, twenty-five picked men, under me--all honorably discharged United States army men."

"You have formed no theory of your own?" queried Kennedy.

MacLeod paused, then drew from his pocket the clipping of a despatch from the front in which one of the war correspondents reported the destruction of wire entanglements with heat supposed to have been applied by the use of reflecting mirrors.

"I'm reduced to pure speculation," he remarked. "To-day they seem to be reviving all the ancient practices. Maybe some one is going at it like Archimedes."

"Not impossible," returned Craig, handing back the clipping. "Buffon tested the probability of the achievement of Archimedes in setting fire to the ships of Marcellus with mirrors and the sun's rays. He constructed a composite mirror of a hundred and twenty-eight plane mirrors, and with it he was able to ignite wood at two hundred and ten feet. However, I shrewdly suspect that, even if this story is true, they are using hydrogen or acetylene flares over there. But none of these things would be feasible in your case. You'd know it."

"Could it be some one who is projecting a deadly wireless force which causes the explosions?" I put in, mindful of a previous case of Kennedy's. "We all know that inventors have been working for years on the idea of making explosives obsolete and guns junk. If some one has. .h.i.t on a way of guiding an electric wave through the air and concentrating power at a point, munitions-plants could be wiped out."

MacLeod looked anxiously from me to Kennedy, but Craig betrayed nothing by his face except his interest.

"Sometimes I have imagined I heard a peculiar, faint, whirring noise in the air," he remarked, thoughtfully. "I thought of having the men on the watch for air-ships, but they've never seen a trace of one. It might be some power either like this," he added, shaking the clipping, "or like that which Mr. Jameson suggests."

"It's something like that you meant, I presume, when you called it a 'phantom destroyer' a moment ago?" asked Kennedy.

MacLeod nodded.

"If you're interested," he pursued, hastily, "and feel like going down there to look things over, I think the best place for you to go would be to the Sneddens'. They're some people who have seen a chance to make a little money out of the boom. Many visitors are now coming and going on business connected with the new works. They have started a boarding-house--or, rather, Mrs. Snedden has. There's a daughter, too, who seems to be very popular." Kennedy glanced whimsically at me.

"Well, Walter," he remarked, tentatively, "entirely aside from the young lady, this ought to make a good story for the Star."

"Indeed it ought!" I replied, enthusiastically.

"Then you'll go down to Nitropolis?" queried MacLeod, eagerly. "You can catch a train that will get you there about noon. And the company will pay you well."

"MacLeod, with the mystery, Miss Snedden, and the remuneration, you are irresistible," smiled Kennedy.
