Too late. Something—someone—struck me from behind, throwing me forward. I landed heavily, facedown on the ground, with the person already on top of me. I closed my eyes and waited for a knife. There was nothing. Nothing but silence and the knees that pinned my back. A moment passed, and it came to me that the knees were not so very heavy and were placed so that their pressure did not hurt. “Patroclus.” Pa-tro-clus.
