The catastrophe must have been a gigantic one to have flung up that fossil tooth from strata far beneath the level of the earth's surface. More, there were even traces of archaean deposits around the borders of the pool, whose depth, in the center, was ascertained to be 164 feet.

Black, silent, uninhabited, unstirred save by a passing breeze, the pool had remained those five years past. The spot was shunned as haunted or accursed by the superstitious country folks. Dense underbrush had grown up around it.

Periodically, Jim had gone out to visit it. That was how he had come to invest in a private plane. It was only an hour to the flying-fields, and less than an hour from there to Peconic Bay. What he expected to achieve he did not know. In the back of his mind was the belief that some day he would light upon some clue that would tell something of the unusual catastrophe.

And then that afternoon he had been shaken to the depths when a message came to him in Lucille's voice over the telephone:

"I've heard from dad!"


inging his way eastward through the storm, Jim Dent was mentally reconstructing all that had led up to the present moment.

Lucille had finished her high school course and gone into business life. Jim had found a position for her as secretary to a small group of physicists, who were conducting private investigations, a position for which her training well fitted her. She had done well. He had kept in touch with her.

Six months before, their relations had altered. They had realized that they were in love with each other. In the months that followed they had discovered all sorts of things about each other that neither had suspected, which might be summed up by saying that they had become all in all to each other.
