The encounter already had the same edge of unease—the aura, the heightened epileptic foreboding—many events had taken on in the wake of the Shrander, as if that entity cast some special kind of illumination of its own. But at the time Kearney still considered himself as a kind of apprentice or seeker. He still hoped to gain something positive. He was still trying to see his retreat from the Shrander as accompanied by a counter-trajectory—a movement towards it—from which something like a transformational encounter might yet proceed. But the truth was that, by the time he met Sprake, he had been throwing the dice, and making random journeys, and getting nowhere, for what seemed like a lifetime. He felt a flicker of vertigo (or perhaps it was only the train starting up again, to drift, slowly at first then faster and faster, towards Hampstead South) and, thinking he was going to fall, reached a hand out to Sprake’s shoulder to steady himself.

“How do you know?” he said. His own voice sounded hoarse and threatening to him. It sounded disused.

Sprake eyed him for a second, then chuckled round at the occupants of the carriage.

“A nudge,” he said, “is as good as a wink. To a blind horse.”

He had slyly removed himself as Kearney reached for him. Kearney half fell into the woman hiding behind the Daily Telegraph, righted himself with an apology, and in that instant saw how good the body is at making metaphors. Vertigo. He was in flight. Nothing good would ever come of this now. He had been falling from the moment the dice came into his hands. He got off the train with Sprake, and they walked off across the noisy, polished concourse and out into Euston Road together.

In the years that followed they developed their theory of the Shrander, though it contained no elements of explanation, and was rarely articulated except by their actions. One Saturday afternoon on a train to Leeds, they murdered an old woman in the draughty space between the carriages, and, before stuffing her into the toilet cubicle, wrote in her armpit with a red gel pen the lines, “Send me an eon heart/Seek it inside.” It was their first joint effort. Later, in an ironic reversal of the usual trajectory, they flirted with arson and the killing of animals. At first Kearney gained some relief, if only through the comradeship—the complicity—of this. His face, which had taken on a look so hollow he might have been dead, relaxed. He gave more time to his work.

But in the end, complicity was all it turned out to be. Despite these acts of propitiation, his circumstances remained unchanged, and the Shrander pursued him everywhere he went. Meanwhile, Sprake took up more and more of his time. His career languished. His marriage to Anna ended. By the time he was thirty, he was sclerotic with anxiety.

If he relaxed, Sprake kept him up to the mark.
