"And you waited—say ten minutes, before you called for help, and even then you went outside hunting a doctor! What were you doing in those ten minutes?"

Wardrop shut his lips and refused to reply.

"If Mr. Fleming shot himself," the detective pursued relentlessly, "there would be powder marks around the wound. Then, too, he was in the act of writing a letter. It was a strange impulse, this—you see, he had only written a dozen words."

I glanced at the paper on the table. The letter had no superscription; it began abruptly:

"I shall have to leave here. The numbers have followed me. To-night—"

That was all.

"This is not suicide," Hunter said gravely. "It is murder, and I warn you, Mr. Wardrop, to be careful what you say. Will you ask Doctor Gray to come in, Mr. Knox?"

I went across the hall to the room where the noise was loudest. Fortunately, Doctor Gray was out of the game. He was opening a can of caviar at a table in the corner and came out in response to a gesture. He did not ask any questions, and I let him go into the death chamber unprepared. The presence of death apparently had no effect on him, but the identity of the dead man almost stupefied him.

"Fleming!" he said, awed, as he looked down at the body. "Fleming, by all that's sacred! And a suicide!"

Hunter watched him grimly.
