The autopsy helped not at all. The man was dead; it was apparently a natural death. “Not a scratch nor a mark on him,” was the report. But: “… next time it will be you,” the note with the staring eye had warned the Secretary of State. The writer of it was taking full credit for the mysterious death.

Robert Delamater had three small bits of metal, like tiny shot, and he racked his brain to connect these with the death. There were fingerprints, too, beautifully developed upon the mysterious missives—prints that tallied with none in the records. There were analyses of the paper—of the ink—and not a clue in any of them.

Just three pellets of metal. Robert Delamater had failed utterly, and he was bitter in the knowledge of his failure.

“He had you spotted, Del,” the Chief insisted. “The writer of these notes may be crazy, but he was clever enough to know that this man did see the Secretary. And he was waiting for him when he came back; then he killed him.”

“Without a mark?”

“He killed him,” the Chief repeated; “then he left—and that’s that.”

“But,” Delamater objected, “the room clerk—”

“—took a nap,” broke in the Chief. But Delamater could not be satisfied with the explanation.

“He got his, all right,” he conceded, “—got it in a locked room nine stories above the street, with no possible means of bringing it upon himself—and no way for the murderer to escape. I tell you there is something more to this: just the letter to the Secretary, as if this Eye of Allah were spying upon him—”

The Chief waved all that aside. “A clever spy,” he insisted. “Too clever for you. And a darn good guesser; he had us all fooled. But we’re dealing with a madman, not a ghost, and he didn’t sail in through a ninth story window nor go out through a locked door; neither did he spy on the Secretary of State in his private office. Don’t try to make a supernatural mystery out of a failure, Del.”
