Dr. Kennedy was angry. A deeper red than that of constitutional Scotch and soda suffused his face, as he answered:

“Your father’s son.”

“Now just what do you mean?”

“Damn it, man, you can’t ask me to be plainer spoken than that. But if you will, all right-Isaac Ford’s son-Joe Garland-your brother.”

Percival Ford sat quietly, an annoyed and shocked expression on his face. Kennedy looked at him curiously, then, as the slow minutes dragged by, became embarrassed and frightened.

“My God!” he cried finally, “you don’t mean to tell me that you didn’t know!”

As in answer, Percival Ford’s cheeks turned slowly grey.

“It’s a ghastly joke,” he said; “a ghastly joke.”

The doctor had got himself in hand.

“Everybody knows it,” he said. “I thought you knew it. And since you don’t know it, it’s time you did, and I’m glad of the chance of setting you straight. Joe Garland and you are brothers-half-brothers.”

“It’s a lie,” Ford cried. “You don’t mean it. Joe Garland’s mother was Eliza Kunilio.” (Dr. Kennedy nodded.) “I remember her well, with her duck pond and taro patch. His father was Joseph Garland, the beach-comber.” (Dr. Kennedy shook his head.) “He died only two or three years ago. He used to get drunk. There’s where Joe got his dissoluteness. There’s the heredity for you.”

“And nobody told you,” Kennedy said wonderingly, after a pause.

“Dr. Kennedy, you have said something terrible, which I cannot allow to pass. You must either prove or, or… ”

“Prove it yourself. Turn around and look at him. You’ve got him in profile. Look at his nose. That’s Isaac Ford’s. Yours is a thin edition of it. That’s right. Look. The lines are fuller, but they are all there.”

Percival Ford looked at the Kanaka half-breed who played under the hau tree, and it seemed, as by some illumination, that he was gazing on a wraith of himself.
