SIR OWAIN WAS AWAKE AND ALERT WHEN SEBASTIAN FINALLY returned to the stairs landing and dropped back into his place on the floor beside him. The man didn’t seem to have much strength for rising, and didn’t try. But his manner was eager enough.

“Well,” he said, “did you see them? The monsters?”

Sebastian took a deep and heavy breath; when he let it go, it was as if a small measure of his pain was washed out of him with it.

“No,” he said. “Not monsters.”

“What, then?”

Sebastian looked down and made no reply. Sir Owain went on, “You’ve seen her. Haven’t you? You can see her too? I’ve always known she was out there. But she always runs from me. What did she say? Did she mention me at all?”

Sebastian looked at him then. He knew that Sir Owain was speaking of his own wife, not of Elisabeth. But he was willing to let Sir Owain believe that his were the only ghosts that haunted the premises.

He said, “What would you want her to say?”

“Don’t just tell me what you think I want to hear,” Sir Owain said. “Tell me honestly. Did she say if I can ever be forgiven?”

Sebastian hesitated, and considered his own experience. Then told him, “She said to let her go.”

“Let her go? She said that? What does it mean?”

“What do you want from her?” Sebastian said. “She can’t come back to you. Stop wondering when the pain will go. It won’t. It’s part of what she left you. You’ll have to learn to love it.”

“What about my son?”

“From what I know, your son is happy,” Sebastian said.

“Did he have a message for me?”

“I’m sure he wants you not to worry. You’ve suffered enough. Believe that he forgives you.”

Sir Owain lowered his head, and his shoulders began to shake with silent weeping. Sebastian had mixed feelings about the lie, but no conscience. What mattered, here? He had his own consolation, rooted in a new and very shaky faith; let Sir Owain now have his.

He put his hand on Sir Owain’s shoulder.

“It’s over,” he said. “Now, please. Where did you hide those keys? I need your telephone.”

THE KEYS WERE in the hallway cabinet, the one that contained the warship model. The glass lid lifted, and the keys were inside one of the steamer’s funnels. Sir Owain unlocked the study door and reconnected the telephone, which took him no more than a minute.

Sebastian placed his call, and as he waited for a messenger to return with someone from the Sun Inn to speak to him, he became aware that Sir Owain was no longer standing in the doorway. He felt a twinge of alarm. Sir Owain was subdued now, but far from harmless. Dr. Hubert Sibley lay dead, somewhere hereabouts. That might not be enough to save the tinker, but it would remove Sir Owain from human society.

Dolly came to the telephone. Not Stephen Reed, not Parish Constable Bill Turnbull, but the Sun Inn’s cook. She began to tell him that the two men were already on their way to Arnside Hall; they’d made a troubling discovery, but she did not know what it was. While she was still explaining, Sebastian heard a shout. It came from outside. Sir Owain must have taken the keys and opened the main door.

Sebastian heard, “Monster! Monster!” and then the sound of a gunshot, ferociously loud in the courtyard. “Oh, Lord,” he said. He abandoned the telephone and ran into the hallway, skidding when he hit the rug, but not stopping as he dived onward toward daylight and the open air.

Sebastian had once seen half of a man’s head blown clean off, gone from the eye sockets up.

Much the same thing had happened to Thomas Arnot, Sir Owain’s chauffeur, as he’d stood trying to drown a young woman at the horse trough. Only he didn’t seem to know it yet. His body was still standing, half turned toward Sir Owain. Sir Owain stood in the middle of the courtyard with his hunting rifle half lowered. Arnot, his brains gone, seemed perfectly capable of carrying on without them. He seemed about to release his victim and start a jerky walk toward his would-be executioner.

But then the pretense crumbled, and the chauffeur’s body fell. His legs gave way, and he slid to the ground like a rotten building falling into its own foundations. Sir Owain still held the rifle, but Sebastian had a more pressing concern. Arnot’s victim remained half submerged and had ceased to struggle.

The water in the trough was all befouled with blood and fragments of bone. Even after Sebastian had pulled her out of it and lowered her to the courtyard floor, her long hair streaming like a mermaid’s, it was several seconds before he recognized Evangeline. He froze in horror. She did not move, or breathe.

“Here,” Sir Owain said, thrusting the hunting rifle into Sebastian’s hands and shoving him aside. “Delay can be fatal.”

He moved with purpose. He rolled Evangeline to lie facedown and drew up one of her arms so that her forehead could rest upon it, keeping her head clear of the ground. He placed his hands against the small of her back and pressed on it, in a more thorough version of the technique he’d used to keep Sebastian alive. Water streamed from Evangeline’s nose and mouth, as if squeezed from a goatskin. She showed no discomfort, or even awareness. Though she drew in breath when Sir Owain removed his weight from her, she gave no voluntary sign of life at all. Sir Owain repeated the action, again and again, the abdominal pressure forcing her diaphragm upward to act upon her lungs.

Sebastian looked down at the rifle in his hands. It was a large-bore, single-shot buffalo gun. Little wonder that it had caused such damage at this range.

“You see?” Sir Owain said, with a sideways glance toward Arnot’s body. “They do. They walk among us. Invisible to all.”

Evangeline suddenly spasmed and began a coughing fit just as the vehicle bringing Stephen Reed made its noisy entrance into the Hall courtyard.

Stephen Reed jumped down from the wagon and was arrested by the sight before him. Sebastian with the hunting rifle. The bedraggled sea creature that was Evangeline. Sir Owain crouching over her.

And the body of Thomas Arnot, his head topped like an egg, his body’s blood now snaking across the courtyard stones in search of a drain.

Sebastian laid down the rifle and helped Sir Owain to lift Evangeline to a sitting position. She was dazed and seemed not to know where she was.

“Who did this?” Stephen Reed said, torn between the fascinating sight of the mutilated chauffeur and concern for Evangeline.

Sebastian was about to speak, but Sir Owain spoke first.

“I did,” he said, and a peculiar little smile played about his lips.

He said, “I slew the beast.”
