“Then that cuts out all suicide idea.”

“It does and it doesn’t. You may as well say the locked up room cuts out all idea of a murder.”

“But it must be one or the other. And isn’t it more plausible to look for some way that the murderer could have gone away and left the room locked, than to think up a way that the suicide could have disposed of this weapon?”

“Yes, that’s so, but I want you to investigate both possibilities. You see, if you could prove a suicide, that would free Miss Austin at once. And—if things go against her—I want you to—oh, hang it, it’s hard to put into words—”

“I’ll do that,” said Fibsy, “if things go against Miss Austin, you want Mr. Stone to frame up suicide, and declare it the truth.”

“Exactly that,” and Trask looked relieved at the thought all his cards were on the table. “I don’t want Miss Austin suspected, but I do want to know if she’s innocent.”

“Any other suspects?” asked Stone.

“Not definite ones. There’s the Japanese who absconded that same night, and of course, there’s the secretary, Gordon Lockwood. I’d like to suspect him, all right, and he has a round silver penholder that just fits the wound that killed Waring. But it doesn’t look like he did it, he never would have left the penholder in evidence, and he would have arranged matters to look more like a suicide. Then, too, how could he lock the door behind him?”

“That question must be answered first of all,” said Stone. “I’ll examine the room, of course, but after the local police and detectives have done that, I doubt if I find anything enlightening. So far as I can see, this whole affair is unique, and I think we will find some surprising evidence and soon. Tell me more of this Miss Austin. Who is she?”

“Nobody knows. In fact, they call her Miss Mystery, because so little is known of her. She appeared here in Corinth from nowhere. She knew no one, and as she began to make acquaintances somebody brought her over here. She met Doctor Waring, and inside of twenty-four hours had so bewitched him that it would seem he had her visiting him in his study late at night. She said at first, she wasn’t here, but as she left the impress of her dress trimmings on that chair-back, and as she has a ruby pin and a lot of money that were in the Doctor’s possession, it looks, one might say, a bit queer.”
