Mrs. Belswin laughed long and loudly.

"Do you, indeed? And may I ask how you intend to stop me?"

Mr. Dombrain leaned across the desk, glanced round to make sure they were alone, then whispered slowly--

"By asking you how you killed your husband."

She sprang to her feet with a pale face, her eyes flashing fiercely.

"It's a lie! You know I had nothing to do with it."

"I'm afraid a jury wouldn't take that view if they heard my evidence."

"Your evidence! the evidence of a felon."

"That's a pretty name, but instead of abusing me, you'd better look after yourself."

Mrs. Belswin sat down again and spoke deliberately.
