“It will never be cleared up,” said the pale Symon.  “If anybody could clear it up, you could.  But nobody could.”

“I rather think I could,” said another voice from outside the group, and they turned in surprise to realize that the man in the black robe had spoken again.

“You!” said the colonel, sharply.  “And how do you propose to play the detective?”

“I do not propose to play the detective,” answered the other, in a clear voice like a bell.  “I propose to play the magician.  One of the magicians you show up in India, Colonel.”

No one spoke for a moment, and then Horne Fisher surprised everybody by saying, “Well, let’s go upstairs, and this gentleman can have a try.”

He stopped Symon, who had an automatic finger on the button, saying:  “No, leave all the lights on.  It’s a sort of safeguard.”

“The thing can’t be taken away now,” said Symon, bitterly.

“It can be put back,” replied Fisher.

Twyford had already run upstairs for news of his vanishing nephew, and he received news of him in a way that at once puzzled and reassured him.  On the floor above lay one of those large paper darts which boys throw at each other when the schoolmaster is out of the room.  It had evidently been thrown in at the window, and on being unfolded displayed a scrawl of bad handwriting which ran:  “Dear Uncle; I am all right.  Meet you at the hotel later on,” and then the signature.

Insensibly comforted by this, the clergyman found his thoughts reverting voluntarily to his favorite relic, which came a good second in his sympathies to his favorite nephew, and before he knew where he was he found himself encircled by the group discussing its loss, and more or less carried away on the current of their excitement.  But an undercurrent of query continued to run in his mind, as to what had really happened to the boy, and what was the boy’s exact definition of being all right.

Meanwhile Horne Fisher had considerably puzzled everybody with his new tone and attitude.  He had talked to the colonel about the military and mechanical arrangements, and displayed a remarkable knowledge both of the details of discipline and the technicalities of electricity.  He had talked to the clergyman, and shown an equally surprising knowledge of the religious and historical interests involved in the relic.  He had talked to the man who called himself a magician, and not only surprised but scandalized the company by an equally sympathetic familiarity with the most fantastic forms of Oriental occultism and psychic experiment.  And in this last and least respectable line of inquiry he was evidently prepared to go farthest; he openly encouraged the magician, and was plainly prepared to follow the wildest ways of investigation in which that magus might lead him.

“How would you begin now?” he inquired, with an anxious politeness that reduced the colonel to a congestion of rage.
