"Accident!" she repeated.

"I notice that you limp slightly."

"Oh, it was a long time ago. I don't feel anything of it now."

Quarles handed her some cake.

"It is very good of you to come," he went on, "and I hope you are going to let us persuade you to be definite."

She nodded at Cockran.

"I have told him that I am not sure. I am going to stick to that."

"The fact is, we are especially anxious to solve this mystery," Quarles went on, "and I believe you are the only person who can help us. Now, from certain inquiries which I have been making I have come to the conclusion that Mr. Parrish is not dead."

"Not dead!" the woman exclaimed.

I saw Cockran look enquiringly at Quarles, but he did not say anything. The professor had evidently persuaded the inspector to let him carry out this investigation in his own way.
