"But he must have been seen somewhere!" insisted Sandy.

"He was!" answered Elmer. "He was seen in the vicinity of this mine!"

"Wow, wow, wow!" exclaimed Sandy.

"What was he doing here?" asked Will.

"Wandering about the premises."

"Now I can tell you the rest," Will said with a chuckle.

"Go on, then," advised Elmer.

"From the meeting of the board of directors that night," Will went on, whimsically, "this man Stephen Carson went directly to a safety deposit vault where three or four hundred thousand dollars' in the way of cash and jewelry, were hidden. He took the whole bundle and disappeared. Is that anywhere near right, Elmer?"

"Go on!" Elmer replied.

"Then in two weeks time he comes back and says that he don't know where he put the jewelry, but that he thinks he hid it in this mine. And, as they can't find any place where he hocked the jewelry, or put it up to carry out some gigantic Wall street plan, they are forced to believe that he really did mislay the jewelry while temporarily out of his head. Is that anywhere near right?"
