"When I come back I shall have found the silver." He spoke quietly, and there was nothing unusual in his voice, but glancing at his eyes the girl understood what he had left unspoken.

If this man did not return with his object accomplished, she felt it would be because he would not come back at all.
Then there was another silence more oppressive still, until Alton held out his hand.

"I must be going," he said.
Alice Deringham was conscious of a little thrill as her fingers rested in his big, hard palm, and when he released them waited for a moment with a curious expectancy.
"You will take my good wishes with you," she said.
Alton bent his head.

"I am doing this thing because I feel I have to," he said very slowly.

"I could come and see you at Vancouver when I come back ?" The light was dim, but the girl moved her head a little so that the man did not see her face.
