you, to the English mind—to surround their wearisome and perilous errand in this country with a certain halo of the marvelous and the supernatural. Their boy is unquestionably a sensitive subject to the mesmeric influence—and, under that influence, he has no doubt reflected what was already in the mind of the person mesmerizing him. I have tested the theory of clairvoyance—and I have never found the manifestations get beyond that point. The Indians don't investigate the matter in this way; the Indians look upon their boy as a Seer of things invisible to their eyes—and, I repeat, in that marvel they find the source of a new interest in the purpose that unites them. I only notice this as offering a curious view of human character, which must be quite new to you.

"Why, Mr. Murthwaite? That's what I want to know! Why?"
"Because no Indian, Mr. Bruff, ever runs an unnecessary risk. The clause you drew in Colonel Herncastle's Will, informed them (didn't it?) that the Moonstone was to pass absolutely into Miss Verinder's possession on her birthday. Very well. Tell me which was the safest course for men in their position? To make their attempt on the Diamond while it was under the control of Mr. Franklin Blake, who
