He was no match for her. He had to obey.

But if she was cruel in other respects, she made a rare listener. Her eyes sparkled and her soft cheeks glowed with excitement as his tale unfolded. When the devilish workings of the blackmailing scheme were made clear to her, her indignation knew no bounds.

"Come to me after you have done your work," she murmured, "and perhaps my answer will be different!"

"Oh, Kate!" he said, reaching for her hand.

As Jack Norman's secretary I'm bound to become a pretty well-known figure around town, and it stands to reason I can't do much sleuthing in that character. I've get to have a disguise. I've got to lead a double life. I'll work while Bobo sleeps."
