This puzzled me yet more; and a thought coming into my head, I asked if
he and my father had been twins.

He jumped upon his stool, and the horn spoon fell out of his hand upon
the floor. "What gars ye ask that?" he said, and he caught me by the
breast of the jacket, and looked this time straight into my eyes:
his own were little and light, and bright like a bird's, blinking and
winking strangely.

"What do you mean?" I asked, very calmly, for I was far stronger than
he, and not easily frightened. "Take your hand from my jacket. This is
no way to behave."

My uncle seemed to make a great effort upon himself. "Dod man, David,"
he said, "ye should-nae speak to me about your father. That's where the
mistake is." He sat awhile and shook, blinking in his plate: "He was all
the brother that ever I had," he added, but with no heart in his voice;
and then he caught up his spoon and fell to supper again, but still
shaking.

Now this last passage, this laying of hands upon my person and
sudden profession of love for my dead father, went so clean beyond my
comprehension that it put me into both fear and hope. On the one hand,
I began to think my uncle was perhaps insane and might be dangerous;
on the other, there came up into my mind (quite unbidden by me and even
discouraged) a story like some ballad I had heard folk singing, of a
poor lad that was a rightful heir and a wicked kinsman that tried
to keep him from his own. For why should my uncle play a part with a
relative that came, almost a beggar, to his door, unless in his heart he
had some cause to fear him?
