"I have no doubt you are; and on a large scale; if there is room for another, I should be glad to join the train."

"Ha! ha! I'll save you the trouble. I'll meet you half way. But, to be serious, I am watched, spied and followed by some enemy to that good friend whose sacred cause we have undertaken. Forgive me for saying 'we.'"

"I am too proud of the companionship to let you off. 'We' is the word."

"Then advise me what to do. I want to retaliate. I want to discover who is watching me, and why. Can you advise me? Will you?"

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.
