There was a huge wire fence that ran along the length of the house and turned in at the top, extending further along in either direction, further than she could possibly see. The fence was very high, higher even than the house they were standing in, and there were huge wooden posts, like telegraph poles, dotted along it, holding it up. At the top of the fence enormous bales of barbed wire were tangled in spirals, and Gretel felt an unexpected pain inside her as she looked at the sharp spikes sticking out all the way round it.
