AT THE hospital they told me I had been found half-frozen in Kingsport Harbor at dawn, clinging to the drifting spar that accident sent to save me. They told me I had taken the wrong fork of the hill road the night before, and fallen over the cliffs at Orange Point—a thing they deducted from prints found in the snow. There was nothing I could say, because everything was wrong. Everything was wrong, with the broad window showing a sea of roofs in which only about one in five was ancient, and the sound of trolleys and motors in the streets below. They insisted that this was Kingsport, and I could not deny it.
