“Margaret is from Margarites--Greek for pearl. And the reason why faith--But I beg your pardon. Men who live alone talk too much when they are no longer alone. I beg you to forgive me. Tell me, Mr. Merriwether, did you ever hear of Apollonius of Tyana?” “Not until this minute,” answered Tom. He felt almost tempted to ask whether the poor man was dead, but refrained because he was honest enough to admit to himself that the question would savor of bravado. Tom was consumed by curiosity as to what would be the end of it all. To think of it--on Fifth Avenue, New York, in broad daylight--all this! How money was to be made out of him he could not yet see. “I will show his talisman to you--the Dispeller of Darkness!” The man clapped his hands twice. At the summons a negro walked in. He was dressed in plain black and wore a fez. The man spoke some guttural words and the negro salaamed and left the room. Presently he returned with a silver tray on which were seven gold or gilt candlesticks and candles, and seven gold or gilt small trays or plates, on each of which was a pastil. He arranged the seven candlesticks in some deliberate design, carefully measuring the distance of each from the other, and of all from a point in the center. He arranged the plates and pastils about the candlesticks. Then he left the room, to return with a lighted taper, with which he lit the seven candles and the seven pastils. Tiny spirals of fragrant smoke rose languidly in the still air. Again the negro left the room and returned with a small parcel wrapped in a piece of raw silk which he gave to his master. He then went away for good. The man began to mutter something to himself and very carefully took off the silk cover, revealing a wonderfully carved ivory box. He opened the gold-hinged lid and took out a silver case. He opened that and from it took a gold box elaborately though crudely chased. He opened the gold box and within it, oh a little white-velvet pad, was a cross of dull gold curiously engraved. He put the pad, with the cross on it, in the middle of the seven lights. On the arms of the cross and at the intersection Tom saw seven wonderful emeralds remarkable as to size, beautiful as to color. “Look at it, Mr. Merriwether. It is priceless. The gems alone are worth a king's ransom. If you consider it merely as a piece of ancient art there is no telling what a man like Mr. W. H. Garrettson would not give for it. And as a talisman, with its tried wonder-working powers, there is, of course, not enough money in all the world to pay for it.” Tom stretched his hand toward it. “Please! Do not touch it, I beg,” said the man, in a voice in which the alarm was so evident that Tom drew his hand back as though he had seen a cobra on the table. “Not yet! Not yet!” said the man. “It is the most wonderful object in existence. It is a cross that antedates Christ!” “Really?”
