“I wish that great chemical friend of yours, papa,—the wonderful Dr. Layton,—had turned his marvellous mind to the invention of invisible fire. I am dying for a cigar now, and I am afraid to light one.”

“Don't think of it, for mercy's sake!” broke in Trover.

“Pray calm yourself, I have not the slightest fancy for being overtaken by this interesting party, nor do I think papa has either,—not that our meeting could have any consequence beyond mere unpleasantness. If they should come up with us, I am as ready to denounce the deceitful Mr. Trover as any of them.”

“You'll find it, perhaps, a very serious earnest if we're caught.”

“Come, come, Loo, forgive him; he certainly meant all for the best. I 'm sure you did, Trover,” said old Holmes, with the blandest of voices.

“Why, what on earth do you mean?” cried he. “You are just as deep in the plot as I am. But for you, how should I have known about Hawke's having any property in America, or that he had any heir to it?”

“I am not naturally suspicious, Trover,” said she, with mock gravity, “but I declare I begin to believe you are a bad man,—a very bad man!”

“I hope and trust not, Loo,” said old Holmes, fervently; “I really hope not.”
