■-...L'= . --= I was not surprised, for I had hardly thought to find him in. Leisurely I pursued my way over to the laboratory, which at that hour af the night was rather de serted. As I approached, 1 was sur prised not to see any light in it end I quickened my pace. What more surprised and even alarmed jne was that the front door of the darkened building was wide op ’en as I entered. My foot crunched on something brittle. I stooped j and in the light, from a street lamp far up the avenue J saw something gleaming. It was shat tered glass. I looked again at the door. The glass in it was broken completely out. An my eyes be came accustomed to the blackness I saw that all around were splinters of glass, as thongh many windows had been shatter ed. i I was by this time in a high Btate of nerves. What could have happened/I Cautiously, I pushed my way into the hall and stood for a moment, listening. Chapter 13 ! 1 LIKE A ORGAN Down the coridor came a faint ■ound, almost like a groan. I groped forward. As 1 came upon the laboratory door I saw that it was a complete wreck. 1 Inside in the dimness, I could see the tables and chairs thrown about in confusion, wood splin tered, glassware broken. My foot stumbled on some thing soft on the floor, and I bent down and touched it. It moved. I struck a match. It was Kennedy, barely con scious, groaning and moving fit fully, in the flickering light of the match. On his head was a deep gash. Ilis clothes were torn. What othop injury ho had sustained I could not tell. I tried to switch on the light, that something was wrong with the slectricity. Instantly there flashed through my mind what must have happened. Somehow the message from Speed must have been used to decoy him over to his own laboratory where a bomb had been planted. As he pushed open the door it had ex ploded. Only his natural cau tion had saved him from being too close and blown into bits. I looked about hastily. What to dot If I left him, perhaps the attack might be renewed. Call ing for help would do no good now. There was no one on this end of the campus likely to hear. I bent over him. Vaguely he seemed to recognize me. “Walter," he groaned. I stooped down and picked him up staggering under his weight. I felt that I must get him away. Out through the broken glass entrance I man aged to carry him, straining to hold him so that the jagged bits of glass on the ground would not cut him. The air seemed to do him good, for he was overcome quite as much by the noxious fumes of tho chemical infernal ma chine as by the shock. It was not long now before I managed to get a ear and soon 1 had him back in the apartment, in bed under medical care. A devilish attack had been planned on Kennedy and he had received it. The doctor insist ed that rest was imperative. Fret though Kennedy did, it made no difference. For a time at least the Black Menace would be able to operate unhampered. Chapter 14 The Pool of Flame Flaring made Kennedy com fortable and assured that it was merely a question of keeping him quiet for a time, I returned to the laboratory and with the aid of a carpenter whom I man aged to get out of bed under the promise of a substantial bonus, I‘had windows and doors boarded up for the night. Kennedy passed a restless night and was glad enough to be quiet the following day. To reassure him, however, I spent the day at the laboratory, re storing it to its original condi tion as nearly as my unscientific hands could do so. As I worked here and there I came upon evidence that before the explosion had taken place the laboratory itself had been ransacked. There did not seem to be anything missing, though there was much that had been smashed by the explosion. But •***. I then I considered there had been nothing that could have inter ested the Black Menace except the hampering of Kennedy in his work, and if possible remov ing him from the case once and for all. It was a hard job to get the place in order again, but with the aid of Kennedy’s students we were making pretty fair pro gress and I felt sure that in a few days everything would be as shipshape as ever. I was deeply engaged in the work when Speed called, very much excited. “I know that, Kennedy must be kept quiet,” he began, as he looked about with interest on what I was doing, “yet I feel that we must not let up on this fellow fpr an instant.” SPEED IS CORDIAL Speed was very cordial, but i could see that it was really Ken nedy he wanted to see. “i’ve been thinking about that decoy letter that was sent to me the other day,” he finally remarked. “Why should anyone have wanted to get me out there at Trocadero Inn? I’ve been mak ing inquiries and I find there is something about that place that bears investigation. I’ve almost a mind to go out and look it over.” I shook my head. “I afraid it will be a dangerous thing for you, Jack,” I cautioned. “Really I should advise you and Clare against making any avert move as long os Kennedy is laid up.” “Ravenal thinks there may be something to it,” urged Speed, still unconvinced by my presentation. You know how things are,” I urged. “It seems to me that we might better let well enough alone. Every time Kennedy has been away something has hap pened to ether you or Clare.” “I don’t know what to do,” figeted Speed. It is too good a chance to let slip past. Who knows but that just because Kennedy is laid up the Black Menace may have become a little careless. Besides the letter would hardly have been sent to me unless the Black Menace had some reason to depend on this place. I’d like to look it over.” The more I argued against it, the more I could see that it merely confirmed Speed in his desire to investigate. He finally left, and instinctively I knew that he would follow out that clue. I couldnot but fret over the danger. Tell Kennedy I would not, for if he thought as I did I knew very well that he was likely to get out of bed, orders or no orders from the doc tor, and forestall or prevent Speed. I was in a quandary, and fin ally determined that the best thing I could do was to go ahead on my own line, trusting that chance would favor Speed. THE EXPECTED HAPPENS And, indeed, the result was just as I expected, if not quite the way I anticipated, although with such a criminal, or band of criminals as the Black Menace I do not know that one might say that anything might be expected except that which more diaboli cal than imagination. it was m Tne rorenoon that Speed had dropped in on me. Once or twice T called up to find him during the day but was able to get no answer. After the second time, when T called up and was unable to locate Speed, I began to get anxious and call ed up Clare. To my greater anxiety she did not answer, and it was then that I knew that she had gone Avith him on some quest.. Not until late in the evening did I get any Avord. And then it Avas that a car pulled up short at the laboratory. To my great relief, I saAv both Clare and Jack in the doorAvay. But they Avere dishcbelled and looked as though they might have been through a Avreck. Their clothes hung on them Avrinkled, and there Avere several bad burns on their flesh. “For hea\’en’s sake,” I ask ed. “What’s the matter T Where have you been?” Speed forced a smile. “Yoti Avere right,” he answered. “We should not have done it. Yet the temptation Avas too great. We Avent out to the Trocadero.” “Yes,—and wluat happened?” “Clare insips<5 going,” he replied. ' ‘ And it was a correct clue, alright.” I listened in amazement as Speed, with a word now and then from Clare, poured out the remarkable story of how he had gone to the fast road house and had almost succeeded in getting the goods on the criminal whom ' we were pursuing. ALL RIGHT AT FIRST It seemed that Minna Oak leigh had been in reality pretty well known there and starting upon that assumption, which proved to be correct, Speed had played his game cleverly, not disclosing who he really was but posing as one of those who had become involved in the game that was being played at the Mystery Mansion. Everything had gone along famously, and late in the after noon, he gathered by hints that someone, perhaps the Black Menace himself, was expected to meet Madam Rene and Monsieur Jacques at the Trocadero. The moment bad arrived when the meeting was to take place and Speed and Clare were waiting for the arrival of a fast car which was to betray to them the identity of the blackmailer, when suddenly something must have gone wrong. The car was approaching then, perhaps by some secret signal, its occupant must have been ‘warned. Insteau of turning in off the road to the Trocadero, he swept on past, never pausing. Speed and Clare had not ex pected that, but it was only a moment when they were out in Jack’s racer and away. The other car was no mean machine for speed and it was with great difficulty that they hung on to it, as it veered off the road and started up toward the Sound shore of the Island, in the direction of North Harbor. It was an exciting chase, but Speed took the risk, for the prize was a great one. Besides, he knew that it could not last forever. When North Harbor was reached, the other car must turn either back to the city or go out further on the island, and, in either case, he reasoned he had a good chance of catching it. NOT WELL PLANNED Ihere was one thing, however, on which he had not figured. They had reached North Harbor, tearing through the town much to the scandal of the inhabitants. On went the other car until it came to a dock. There the oc cupant of the car had abandon ed it, running out on the end of the dock and leaping into a motorboat with a hunting cabin, which was tied up there, evi dently waiting for him. He was away, leaving them for the moment helpless. It was the work of only a few minutes, however, for Speed to find another fast boat in the neighborhood of the yacht club. In it he and Clare took up the chase again. By this time the Black Menace if indeed, it was the Black Men ace, on whose trail they were, had perhaps a mile start on them. But their commandeered boat proved to be the faster of the two; and it was not long be fore it was evident that they were overhauling them. As their boat gained, Speed seized a megaphone and called for the other boat ahead to stop. But it was without effect. He drew his gun and fired. Back from the pursued boat came an answering shot. f or some minutes there was considerable gun play. Clare and Jack dropping down out of sight so that they would not be quite such good targets. Suddenly Clare exclaimed in consternation. It was evident that it was not so much to hit them that the pursued boat-roan was firing as for another pur pose. The gas tank on their boat had been punctured by a shot and the gasoline was pour ing out in a stream, spreading over the water in an irridescent scum. Another shot and another stream poured forth, as the Black Menace realized that he had correctly located the tank. Still their boat gained, although it was now a question of how long it would maintain its head way, as the gas sank lower in the tank. FAR IN THE LEAD Desperately, the Black Menace pulled two cans of reserve gas from a locker in his boat. He opened them and began pouring them out over the water astern. The gas spread over the water as he sped on. Gradually the headway of Speed’s boat decreased as the gas in the pipe line failed and none reached the carburetor. The engine stopped. No gas was reaching it. The Black Marace was bjr this time far aheajf an< tmt-d£ » tancing them. He turned an3 from the locker pulled what looked like a Costan signal flare. He tore off the top. It flared, and he shot it out in a long curve of smoke and flame. The rocket fell close to Speed’s boat on the water as it hung idly. Instantly, the gaso line that lay heavy all about, surrounding them as they drift ed, was ignited. They were in the midst of what was literally a pool of flame. Around them licked the flames, setting their boat on fire. The heat was intense, scorching the paint and varnish. The inside of the boat was now on fire. It was only a matter of seconds now that they could stand it. Far off the Black Menace was but a speck on the water. A boat was coming toward them with help but it was half a mile or so away, and it was slow. Something had to be done and immediately, or they would be burnt to cinders with help in sight. Speed seized one of the leather cushions which was not yet afire and flung it overboard. It fell, parting the flame and throwing the burning gas to one side for a moment, only to have it, close together again on the surface of the water ominously. Yet it was enough to suggest something to Speed. “There’s just one chance,” he muttered. “Will you follow met” She did not cling to him. That was not Clare’s manner. “Yes,” she answered, her quick mind already divining what was in his thoughts. QUICK ORDERS He leaped to the side of the burning boat, above the scorch ing and smoking pool of flame about them. As he did so, he seized another cushion, motion ing to her to do the same. “Let go of it the moment you strike the water,” he shouted. “Then down—down—with me.” He leaped over, the cushion before him like a shield to part the flames. As he touched the flaming water, thrashing about with the cushion, he cleared just a small space in the flaming pool about himself. Clare was ready. Before the flames on the water could close again she leaped into the space he had cleared. As she struck the water, he seized her. Together they sank, diving down on the angle as far as they could, swimming under water—the blazing oil above them. To come up for air meant horrible destruction, for they could not dive back again fast enough. Once Clare’s breath gave out and she began to rise. Speed seized her and with his last remaining strength man aged to carry both until they bobbed up, a matter of inches be yond the circle of blistering fire. Chapter 15 The False Clue I cannot say that the exper ience Speed had had in his pur suit of the Black Menace had cooled his ardor in the least, al though it did one thing. He was determined now that in any future attempt he would be sure to go alone and thus save Clare the danger of any attack. Having seen that Clare was safely returned to her apartment where a new and trustworthy maid had been placed in charge, Speed lost no time in returning to me at the laboratory. Again he began recounting his experience and his theories, and it was in the midst of it that Ravenal dropped in. “My dear fellow,” remon strated Ravenal as he heard the story, “don’t you see that what you are doing is nothing short of foolhardy ! What is the use of retaining Kennedy, to say nothing of yourself, if you are going to deliberately expose yourself to danger, as well as Miss Claremont!” I had had in mind the same caution to deliver, but was glad that it came from Ravenal, for I felt that it came from him with much better grace than from my self. It had little effect on Speed, however. He seemed, if anything, more determined than ever. VERY LITTLE EFFECT “And another thing,” Speed insisted, brushing aside every argument, “I mean to get at the botton of the connection Bresh* kaya has with this affair.” “That, too, is another matter onrrhicii I ryish caution you,” cirf in Rav' nal. ‘1-re- been do ing a little shadow job on that lady myself ever since she led us that chase up in the Highlands.* As far as I can find out, Bresh kaya, since the death of Thorne, with whom she was really in love, seems to be a changed per son, a very dangerous woman. And, besides, she is very bitter against both you and Miss Clare mont. Watch out for her.” I could see -that the argument had very little effect on Speed. When it came to matching wits he felt himself the equal of any “I’m going to renew my ac quaintance with her just the same.” ho persisted. “Some way Pm going to trap her into tell ing me something. I’m convin ced she knows more than we im ginc.” As he spoke, I was really afraid for Speed. Nor did Ra venal make any concealment of his own concern. “I guess I’ve watched Brcsh kaya as closely as you,” retorted Speed to Ravenal finally. “At least, I think this time I shall be able to cope with her. I know her kind.” Ravenal shook his head. It was plain that he was loathe to allow the young newspaper man to make the attempt. And, as I \thought of it, I myself could see no reason why Speed should be able to take care of himself any Better tBafl others yh# had been enmeshed by the siren. Still, both Speed and Clare had that unfortunate penchant of youth for rushing in where even Kennedy, with his exper ience, would fear to tread. I shrugged. If ho would not listen to Ravenal his own man he would scarecely listen to me. (Continued Next Week - ■ — • --* LET UNCLE 3AM TELL 'EM.
