"Captain Jadby and Steve Agstone might have witnessed."

"No. There is a chance certainly that Agstone might have done so, but one signature would have been of no use. And had Jadby witnessed a new will, he would not have benefited under it. Besides, since he had the will made in the South Seas, and Sir Oliver assuredly wished him to have the money, along with Mona, all that had to be done was to destroy the will made in Mona's favour, and then Jadby, having the cash, could leave her penniless unless she married him. Which is just what has happened," ended Shepworth.

"Of course," said Prelice thoughtfully, "Miss Chent might have been trying, when seen by Steve, to rescue the will from the fire into which it had been thrown by Sir Oliver."

Shepworth wheeled round. "Do you believe that she is guilty?"

"Oh, no. But we must look on all sides. And Agstone——"

"Is a liar," interrupted the barrister quickly. "I don't believe that he saw Mona bending over the fire. She was insensible, by her own showing, from the moment she entered the room until Jadby woke her. And remember that I found her insensible."

"It would help her if you said so."

"I don't agree with you. Were I examined about my presence in the library, I might let slip that the knife——"

"Yes, yes," said Prelice hastily. "I see. It will be better for you to hold your tongue. I hope that Agstone will not appear."

"If he does not, Mona is safe," rejoined Ned, with a sigh of relief. "Oh, poor Mona. Think of her in prison, Dorry."
