"So I heard," said his father steadily. He straightened himself in his chair. "I am sorry. Mr. Greensleeve is a very old friend——"

The library telephone rang; the second man entered and asked if Colonel Mallett could speak to Mr. Dysart over the wire on a matter concerning the Yo Espero district.

Duane, astonished, sprang up asking if he might not take the message; then shrank aside as his father got to his feet. He saw the ghastly pallor on his face as his father passed him, moving toward the library; stood motionless in troubled amazement, then walked to the open window of the conservatory and, leaning there, waited.

His father did not return. Later a servant came:

"Colonel Mallett has retired, Mr. Duane, and begs that he be undisturbed, as he is very tired."


[CHAPTER XV
DYSART]

The possibility that his father could be involved in any of the spectacular schemes which had evidently caught Dysart, seemed so remote that Duane's incredulity permitted him to sleep that night, though the name Yo Espero haunted his dreams.

But in the morning, something he read in the paper concerning a vast enterprise, involving the control of the new radium mines in Southern California, startled him into trying to recollect what he had heard of Yo Espero and the Cascade Development and Securities Company. Tainting its title the sinister name of Moebus seemed to reoccur persistently in his confused imagination. Dysart's name, too, figured in it. And, somehow, he conceived an idea that his father once received some mining engineer's reports covering the matter; he even seemed to remember that Guy Wilton had been called into consultation.

Whatever associations he had for the name of the Cascade Development and Securities Company must have originated in Paris the year before his father returned to America. It seemed to him that Wilton had been in Spain that year examining the recent and marvellously rich radium find; and that his father and Wilton exchanged telegrams very frequently concerning a mine in Southern California known as Yo Espero.
