Then he looked about him in a hopeless way.

He wondered if rescue had yet come, and arose to open the door into the main cabin.

For it required no second glance for him to see that the new-comer was one of the Aurelian’s crew.

The peculiar fit of his diving suit and the life lines were evidence of this.
