"Merely this." Mrs. Fane produced the dagger from her pocket. "This is a stage weapon. The handle is tinsel and glass. It was found by Gander in the dust-hole."

Laura took the weapon and examined it with a pale face. "Go on."

"Really, my dear, there is no more to say. I leave you to draw your own inferences."

"I understand," said Laura rapidly and in a low voice. "You think that Arnold killed the woman?"

"She was his cousin--the dagger is a stage weapon--Mr. Calvert often came to this house. Put two and two together, my dear, and----"

"Stop!" cried Laura furiously. "I don't believe it. Why should Arnold come here and kill his cousin--if she is his cousin?"

"He admitted she was."

"He admitted, according to your own showing, that Flora Brand was. We cannot yet be certain that the dead woman is Flora Brand."

"Going by the similarity of the rooms----"

"That may be a coincidence."
