“Whom would you consider the most able of the lot?”

The old man set a finger on one of the clippings. “Preston Jax,” said he, “is the shrewdest of them all. Sometimes I have thought that he had dim flashes of real clairvoyance. Be that as it may, he has a surprising clientele of which he makes the most, for he is a master-hand at cozening women out of their money. More than once he has been in the courts.”

“Good! I shall see you, then, to-morrow, sir.”

“Clarity of vision go with you, amid your riddles,” said his host with a smile, shuffling the cards which Kent had gathered up for him. “Here is my all-sufficient riddle.

He seized himself by the lobe of the ear with that grip which drowning men reserve for straws. And—to continue the comparison—the ear sank with him beneath the waves of confusion. Mrs. Blair’s first words did not greatly help him.
