Graham rose to his feet instinctively, and for a moment the two men stood in silence, regarding each other.
"You are Ostrog ?" said Graham.
"I am Ostrog." "The Boss ?" "So I am called." Graham felt the inconvenience of the silence.

"I have to thank you chiefly, I understand, for my safety," he said presently.
"We were afraid you were killed," said Ostrog.

"Or sent to sleep again--for ever.

We have been doing everything to keep our secret--the secret of your disappearance.

Where have you been?
How did you get here ?" Graham told him briefly.
Ostrog listened in silence.
He smiled faintly.
