p48 Out Stealing Horses by Per Petterson (Paperback - Jul 13, 2007)
I break horses. I don't tend to them.
It was Jon's gun, that they knew, and their big brother Jon was their hero, and if they had the same role models as I did at that age, he was their Davy Crockett and Hartsfoot and Huckleberry Finn in one person.
Lars got there first, he grabbed the gun and swung it around and shouted, "Look at me now!" And then he pulled the trigger. The report and the shock from the butt sent him to the floor, and he did not aim at anything, he just wanted to hold the wonderful gun and be Jon, and he might have hit the woodbox, or the small window over the steps. But he did not hit any of those things, he hit Odd straight in the heart at close range. If this had been something that happened in a western, those pages would claim that the very name of Odd had been written on that cartridge, or it was written in the stars. But that was not how it was, and Jon knew it where he lay huddled up on the grass of the meadow and saw his father come out of the house with his brother in his arms, and the only book where the name of Odd was written and could not be crossed out was the church registry book.

What had happened was that the twins had been playing in the basement the whole morning. Then they came running upstairs laughing, and stumbling into the corridor through the basement door, and there they saw the hares hanging on the peg, and the gun leaning against the wall.
