“Yes—no. Creaking. A rusty handle turning, or a wooden door forced open until its hinges buckle, or to me, to me it was the sound of something growing. I sometimes imagine that if we could hear trees growing we'd hear them...creak...like that. I knocked again, and the creaking stopped, but a silence began. A silence I didn't feel good about at all. But I felt obliged to do whatever I could do...if I left a door closed and it transpired that somebody might have lived if I had only opened it in time...I couldn't bear that...so I had to try the door no matter what.”
