“Or a cop,” Susannah said. “He might have seen a cop in the wrong place and at the wrong time.”

“Yes. The exact reason-the agent of ka-tet-doesn’t matter. I know from firsthand experience that Mort was as wily as an old fox. If he sensed any slightest thing wrong, he would have called it off and waited for another day.

“I know something else, as well. He hunted in disguise. On the day he dropped the brick on Detta Holmes’s head, he was wearing a knitted cap and an old sweater several sizes too big for him. He wanted to look like a winebibber, because he pushed the brick from a building where a large number of sots kept their dens. You see?”

They nodded.

“On the day, years later, when he pushed you in front of the train, Susannah, he was dressed as a construction worker. He was wearing a big yellow helmet he thought of as a ‘hardhat’ and a fake moustache. On the day when he actually would have pushed Jake into traffic, causing his death, he would have been dressed as a priest.”

“Jesus,” Susannah nearly whispered. “The man who pushed him in New York was Jack Mort, and the man he saw at the way station was this fella you were chasing-Walter.”

“Yes.”

“And the little boy thought they were the same man because they were both wearing the same kind of black robe?”

Roland nodded. “There was even a physical resemblance between Walter land Jack Mort. Not as if they were brothers, I don’t mean that, but both were tall men with dark hair and very pale complexions. And given the fact that Jake was dying when he got his only good look at Mort and was in a strange place and scared almost witless when he got his only good look at Walter, I think his mistake was both understandable and forgivable. If there’s a horse’s ass in this picture, it’s me, for not realizing the truth sooner.”

“Would Mort have known he was being used?” Eddie asked. Thinking back to his own experiences and wild thoughts when Roland had invaded his mind, he didn’t see how Mort could not know… but Roland was shaking his head.

“Walter would have been extremely subtle. Mort would have thought the priest disguise his own idea… or so I believe. He would not have recognized the voice of an intruder-of Walter-whispering deep within his mind, telling him what to do.”

“Jack Mort,” Eddie marvelled. “It was Jack Mort all the time.”

“Yes… with assistance from Walter. And so I ended up saving Jake’s life after all. When I made Mort jump from the subway platform in front of the train, I changed everything.”

Susannah asked, “If this Walter was able to enter our world- through his own private door, maybe-whenever he wanted, couldn’t he have used someone else to push your little boy? If he could suggest to Mort that he dress up like a priest, then he could make somebody else do it… What, Eddie? Why are you shaking your head?”

“Because I don’t think Walter would want that to happen. What Walter wanted is what is happening… for Roland to be losing his mind, bit by bit. Isn’t that right?”

The gunslinger nodded.

“Walter couldn’t have done it that way even if he had wanted to,” Eddie added, “because he was dead long before Roland found the doors on the beach. When Roland went through that last one and into Jack Mort’s head, ole Walt’s messin-around days were done.”

Susannah thought about this, then nodded her head. “I see… I think. This time-travel business is some confusing shit, isn’t it?”

Roland began to pick up his goods and strap them back into place. “Time we were moving on.”

Eddie stood up and shrugged into his pack. “You can take comfort from one thing, at least,” he told Roland. “You-or this ka-tet business- were able to save the kid after all.”

Roland had been knotting the harness-strings at his chest. Now he looked up, and the blazing clarity of his eyes made Eddie flinch backward. “Have I?” he asked harshly. “Have I really? I’m going insane an inch at a time, trying to live with two versions of the same reality. I had hoped at first that one or the other would begin to fade away, but that’s not happening. In fact, the exact opposite is happening: those two realities are growing louder and louder in my head, clamoring at each other like opposing factions which must soon go to war. So tell me this, Eddie: How do you suppose Jake feels? How do you suppose it feels to know you are dead in one world and alive in another?”

The lark sang again, but none of them noticed. Eddie stared into the faded blue eyes blazing out of Roland’s pale face and could not think of a thing to say.

THEY CAMPED ABOUT FIFTEEN miles due east of the dead bear that night, slept the sleep of the completely exhausted (even Roland slept the night through, although his dreams were nightmare carnival-rides), and were up the next morning at sunrise. Eddie kindled a small fire without speaking, and glanced at Susannah as a pistol-shot rang out in the woods nearby.

“Breakfast,” she said.

Roland returned three minutes later with a hide slung over one shoulder. On it lay the freshly gutted corpse of a rabbit. Susannah cooked it. They ate and moved on.

Eddie kept trying to imagine what it would be like to have a memory of your own death. On that one he kept coming up short.

SHORTLY AFTER NOON THEY entered an area where most of the trees had been pulled over and the bushes mashed flat-it looked as though a cyclone had touched down here many years before, creating a wide and dismal alley of destruction.

“We’re close to the place we want to find,” Roland said. “He pulled down everything to clear the sightlines. Our friend the bear wanted no surprises. He was big, but not complacent.”

“Has it left us any surprises?” Eddie asked.

“He may have done so.” Roland smiled a little and touched Eddie on the shoulder. “But there’s this-they’ll be old surprises.”

Their progress through this zone of destruction was slow. Most of the fallen trees were very old-many had almost rejoined the soil from which they had sprung-but they still made enough of a tangle to create a formidable obstacle course. It would have been difficult enough if all three of them had been able-bodied; with Susannah strapped to the gunslinger’s back in her harness, it became an exercise in aggravation and endurance.

The flattened trees and jumbles of underbrush served to obscure the bear’s backtrail, and that also worked to slow their speed. Until midday they had followed claw-marks as clear as trail-blazes on the trees. Here, however, near its starting point, the bear’s rage had not been full-blown, and these handy signs of its passage disappeared. Roland moved slowly, looking for droppings in the bushes and tufts of hair on the tree-trunks over which the bear had climbed. It took all afternoon to cross three miles of this decayed jumble.

Eddie had just decided they were going to lose the light and would have to camp in these creepy surroundings when they came to a thin skirt of alders. Beyond it, he could hear a stream babbling noisily over a bed of stones. Behind them, the setting sun was radiating spokes of sullen red light across the jumbled ground they had just crossed, turning the fallen trees into crisscrossing black shapes like Chinese ideograms.

Roland called a halt and eased Susannah down. He stretched his back, twisting it this way and that with his hands on his hips.

“That it for the night?” Eddie asked.

Roland shook his head. “Give Eddie your gun, Susannah.”

She did as he said, looking at him questioningly.

“Come on, Eddie. The place we want is on the other side of those trees. We’ll have a look. We might do a little work, as well.”

“What makes you think-”

“Open your ears.”

Eddie listened and realized he heard machinery. He further realized that he had been hearing it for some time now. “I don’t want to leave Susannah.”
