Kennedy and I had been hastily summoned from his laboratory in the city by District-Attorney Mackay, and now stood in the luxurious, ornate library in the country home of Emery Phelps, the banker, at Tarrytown. "Camera!—you know the call when the director is ready to shoot a scene of a picture?—well—at the moment it was given and the first and second camera men began to grind—she crumpled—sank to the floor—unconscious!" Hot and excited, Mackay endeavored to reenact his case for us with all the histrionic ability of a popular prosecutor before a jury. "There's where she dropped—they carried her over here to this davenport—sent for Doctor Blake—but he couldn't do a thing for her. She died—just as you see her. Blake thought the matter so serious, so alarming, that he advised an immediate investigation. That's why I called you so urgently."
