"Have you any reason for going?"

"One. I wish to find out why Mrs. Boazoph visited the Hall."

"And what about the tattooed cross, Mr. Fanks?"

"Oh, I shall see that later on. But in the meantime I must pay these visits. Firstly, Taxton-on-Thames. Secondly, Mere Hall. Thirdly, the Isle of Wight and the Rev. Mr. Hersham."

"Humph!" said Crate, doubtfully. "From what you say, I should think Mr. Hersham junior would thwart your plans, if he could."

"I have not the least doubt of it," replied Fanks dryly, "but he is being watched. If he tries to thwart me I shall, at least, have the satisfaction of knowing it. By the way, do you know anything about Bombay?"

"That's in India, isn't it?" said Crate, rather taken aback by the apparent irrelevancy of this question. "I don't know anything about Bombay, Mr. Fanks, except what I've seen in books."

"You must extend your knowledge then; for I may want you to go there in a week or so."

"Has my going there anything to do with this case?" demanded Crate, still very much astonished at the turn the conversation had taken.

"It has everything to do with this case," replied Fanks, enjoying his perplexity, and the confusion of his somewhat slow-moving mind.
