A revolver-shot followed by the crash of glass sounded in our hall. At the same instant the laboratory door burst open and an elderly, distinguished-looking man stumbled in on us, his hat now off, his coat and collar awry, his hair rumpled, and his face wearing a dazed, uncertain expression, as though he did not yet comprehend what had so suddenly taken place. “My God!” he exclaimed, gazing about in a vain effort to restore his dignity and equilibrium. “What was that? I hardly had my hand on the knob when it happened.” A glance was enough to assure Kennedy that the man was unhurt, except for the shock, and in a moment he dashed out into the hall. The front door of the Chemistry Building had been shattered by a revolver-shot. But not even the trace of a skulking figure could be seen on the campus. Pursuit was useless. There was, apparently, no one to pursue. Pale and agitated still, the man sank limply into a chair as I forced a stimulant into his trembling lips. Kennedy closed the door and stood there a moment, a look of inquiry on his face, but without a word. “Some one—must have—shadowed me—all the way,” gasped the man as he gulped hard, “must have seen me come in—tried to shoot me before I had a chance to tell you my story.” It was some minutes before our strange visitor regained his poise, and Craig refrained from questioning him, though I was consumed with curiosity to know the reason of his sudden entrance. When at last he did speak, his first words were so different from anything I had expected that I could hardly believe him to be the same person. In spite of his nervousness, his tone was that of a hard, practical man of business. “I suppose you know something of Maddox Munitions, Incorporated?” he inquired, somewhat brusquely. I did not quite understand a man who could be himself so soon after an episode such as he had been through, nor do I think Kennedy did, either. “I have no interest in ‘war brides,’” returned Craig, coldly. “Nor have I—as such,” the man agreed, apparently rather pleased than otherwise at the stand-off attitude Kennedy had assumed. “But I happen to be Maxwell Hastings, attorney for Marshall Maddox, who was—” Kennedy wheeled about suddenly, interrupting. “Whose body was found floating in Westport Bay this morning. Yes, Mr. Jameson and I have read the little five-line despatch in the papers this morning. I thought there was something back of it.” As for me, I was even more excited now than Kennedy and I could see a smile of satisfaction flit over the face of Hastings. In a few sentences the clever lawyer had extracted from us what others took all manner of time and art to discover. He knew that we were interested, that he could depend on Kennedy’s taking the case. Kennedy and I exchanged a significant glance. We had discussed the thing cursorily at the breakfast-table as we did any odd bit of news that interested us. Already I knew, or fancied I knew, something of the affair. For it was at the time when explosions in munitions plants had furnished many thrilling chapters of news. All the explosions had not been confined to the plants, however. There had been and still were going on explosions less sanguinary but quite as interesting in the Maddox family itself. There was a hundred million dollars as the apple of discord, and a most deadly feud had divided the heirs. Together they had made money so fast that one might think they would not feel even annoyance over a stray million here and there. But, as so often happens, jealousy had crept in. Sudden wealth seemed to have turned the heads of the whole family. Marshall Maddox was reported to have been making efforts to oust the others and make himself master of the big concern.
