“Being a mother was all-consuming. There were so many mistakes you could make, so many ways to lose a child. The whole world was a threat. In the years after Lockie’s birth she became addicted to those current-affair shows that interviewed parents who had made the one fatal mistake. They had let the blind cord dangle on the ground, they had left the pool gate unlocked, they had put the pot too close to the edge of the stove, they had just ducked into the shopping centre and left the child in the car. They had taken their eyes off the ball and that way lay tragedy and regret. Sarah watched to see what mistake had been made and each time had been able to congratulate herself on never making any of those mistakes. But then she had made a mistake—one worthy of a current-affairs show.She had looked away.”
