My sister had fallen overboard because of me. Because I’d been teasing her with a stupid toy laser that I’d snagged that morning from a lucky dip bag. I could have just let her play with the damn laser. It wasn’t even a good one. Just a cheapie I could have replaced in the pound shop for 50p. I’d made enough money that day. Over two hundred pounds in the cards I’d opened. Cards that had meant so much to me that morning only to mean nothing at all that night. I could have given Beth a turn. I could have bought her a lucky dip bag of her own. But I didn’t.
