The counsel reflected a moment, and Helen, who watched him, remarked the power that suddenly came into his countenance and brow.

"You must watch the spies. I have influence in Scotland Yard, and will get it done for you. If you went there yourself they would cross-examine you and decline to interfere. I'll go myself for you and put it in a certain light. An able detective will call on you. Give him ten guineas, and let him into your views in confidence; then he will work the public machinery for you."

"Oh, Mr. Hennessy, how can I thank you?"

"By succeeding. I hate to fail. And now your cause is mine."

Next day a man with a hooked nose, a keen black eye, and a solitary foible (Mosaic), called on Helen Rolleston, and told her he was to take her instructions. She told him she was watched, and thought it was done to baffle a mission she had undertaken; but, having got so far, she blushed and hesitated.

"The more you tell me, miss, the more use I can be," said Mr. Burt.

Thus encouraged, and also remembering Mr. Hennessy's advice, she gave Mr. Burt, as coldly as she could, an outline of Robert Penfold's case, and of the exertions she had made, and the small result.

Burt listened keenly, and took a note or two; and, when she had done, he told her something in return.
