"It is. I told Juliet so. But I cannot explain."

The lovers looked at one another in a dazed fashion. The woman's objection seemed to be senseless. "Surely you don't think Cuthbert killed Aunt Selina?" said Juliet, laughing in a forced manner.

"No. I don't suspect him."

"Then whom do you suspect?" demanded Mallow.

"That I decline to say."

"Will you decline to say it to the police?"

Mrs. Octagon stepped back a pace. "Yes, I should," she faltered.

Cuthbert Mallow looked at her, wondering why she was so agitated, and Juliet stole her hand into his. Then he addressed her seriously.

"Mrs. Octagon," he said, "your remark about my uncle leads me to think you suspect him."

"No I don't. But you can't marry Juliet on account of this crime."
