"Then why did you tell me to ask her about Ferris?"

"Because I wanted to be sure of something; and that fainting has enlightened me."

"Can't you tell me more?" cried Gebb, with some indignation.

"No, I cannot," answered Prain, bluntly. "Get Miss Wedderburn's permission, and I will. But even if you did know, the knowledge would be of no use to you."

"Has Miss Wedderburn any theory about this murder?"

"Not that I know of. You saw her last, Mr. Gebb."

"Does she know who killed Miss Gilmar?"

"Why not ask her?" said Prain, evading the question.

"I did; and I can't make out what she means. She says that Dean is innocent, but won't give her reason. Now, Parge declares that Dean is guilty."

"Well, Mr. Gebb, perhaps he is."
