our minds, and he turned abruptly aside, as he went in search of the janitor or the superintendent of the building. Left by myself I stared at the silent door. It was an ordinary-looking door, at the end of a small side passage which communicated with the main hall or lobby of the building. It was inconspicuous, and as the passage had an angle in it, Amos Gately could easily have gone in and out of that door without exciting comment. Of course, the janitor would know all about it; and he did. He returned with Mr. Talcott, muttering as he came. “I always said Mr. Gately’d get caught in that thing yet! I don’t hold with them automaticky things, so I don’t. They may go all right for years and then cut up some trick on you. If that man’s caught in there, he must be pretty sick by this time!” “Does Mr. Gately use the thing much?” I asked. “Not so very often, sir. Irregular like. Now, quite frequent, and then, again, sort of seldom. Well, we can’t open it, Mr. Talcott. These things won’t work, only just so. After anybody gets in, and shuts the door, it can’t be opened except by pressing a button on the inside. Can’t you get in upstairs?” “No,” said Talcott, shortly. “Get help, then, and break the door down.” This was done, the splintered door fell away, and there, in a crumpled heap on the floor of the car, was Amos Gately,—dead. CHAPTER IV The Black Squall CHAPTER IV If I had thought Mr. Talcott somewhat indifferent before, I changed my opinion suddenly. His face turned a ghastly white and his eyes stared with horror. There was more than his grief for a friend, though that was evident enough, but his thoughts ran ahead to the larger issues involved by this murder of a bank president and otherwise influential financier. For murder it was, beyond all doubt. The briefest examination showed Mr. Gately had been shot through the heart, and the absence of any weapon precluded the idea of suicide. The janitor, overcome at the sight, was in a state bordering on collapse, and Mr. Talcott was not much more composed. “Mr. Brice,” he said, his face working convulsively, “this is a fearful calamity! What can it mean? Who could have done it? What shall we do?”
