One single figure, more or less human in form, toiled its way up the hillside: an elderly man wearing a dull, featureless robe, covering as meager as if it had been snatched from the hostile emptiness of the sky. The man, Wilbur Mercer, plodded ahead, and, as he clutched the handles, John Isidore gradually experienced a waning of the living room in which he stood; the dilapidated furniture and walls ebbed out and he ceased to experience them at all. He found himself, instead, as always before, entering into the landscape of drab hill, drab sky. And at the same time he no longer witnessed the climb of the elderly man. His own feet now scraped, sought purchase, among the familiar loose stones; he felt the same old painful, irregular roughness beneath his feet and once again smelled the acrid haze of the sky — not Earth's sky but that of some place alien, distant, and yet, by means of the empathy box, instantly available.

Who? he wondered, peering to see his tormentor. The old antagonists, manifesting themselves at the periphery of his vision; it, or they, had followed him all the way up the hill and they would remain until at the top —
