The professor offered me a seat on a soft sofa-blue cornflowers on a maroon background. He wheeled to a position facing me and gave me a good long look. "Rough day," he said.

It wasn't a question. I guess I looked even worse than I felt.

"Still wrestling with the news?" he asked.

I laughed.

"Something I said?"

"The news is wrestling back."

I described what had happened in my hotel room. As I spoke, the professor closed his eyes. He listened as though he was in pain.

Sue Ling's voice preceded her entrance. "Coffee will be ready in a . . . Grant, you look horrible!" she cried.

"Thanks. I'd hate to feel this lousy and n.o.body knew."

It took half an instant for Sue to put the pieces together. She's quick. I was impressed not only with the speed of her deductive reasoning, but with the fact that she hadn't been listening to our conversation from the kitchen.

But what she deduced scared her, and the expression of horror on her face reminded me that I had demon blood racing through my veins. All of a sudden she couldn't look at me.

Her gaze laboriously avoiding me, she inched closer to the professor and placed a hand on his arm. The professor didn't acknowledge it. He seemed comfortable with it.

"Anyway," Sue said to the floor, "the coffee will be ready in a minute. I set out sugar and spoons. If you want creamer, it's in the refrigerator. Oh, and there are some cookies on the shelf beneath the toaster oven. The shortbread kind. They're the professor's favorite." She gave his arm a pat.

"Thank you, Sue," the professor said, reaching for her hand. Squeezing it.

"It's been a long day," she said. "I'm going to go to bed."

Her next move was of great interest to me. Which direction would she go from here? To the back of the house? Or out the front door?

She bent over and kissed the professor on the forehead. "Good night," she said.

"Sleep well, Sue," the professor replied.

Sue Ling then reached behind a chair, retrieved her purse, and let herself out the front door. I smiled. I think it was the first smile I'd smiled all day.

Now that we were alone, I said, "How do I fight angels, Professor?"

Hands clasped in his lap, he thought a moment. "Have you read the narrative accounts I sent you? The ones Abdiel dictated to me?"

"One of them."

"How many do you have?"

"Two. Are there more?"

The professor's eyes lit up. "Oh my, yes! Accounts of Lucifer's attempt to corrupt the kingly Davidic line from which the Messiah was promised; heaven's major offensive through the incarnation of the Son; the three years of head-to-head battle between Lucifer and Jesus; the battle of the cross; the raid on Sheol with the release of the captives. All of it. It's fascinating."

"Will it help me fight them?"

"Those narrations are for you."

"Me? I thought Abdiel didn't like me."

"He doesn't. That's why he's dictating the narrative to me. Heaven has taken an interest in you, Grant."

"I guess I should be flattered."

"If you had any sense, you'd be scared."

The comment reminded me how scared I was. I got up and paced.

"So how do I fight them?" I asked again. "I'm tired of being Myles Shepherd's . . ."

It was going to take a while to adjust to his new name.

"Of being Semyaza's p.a.w.n. How do I fight him?"

I was eager to get my hands on something I could use to pummel Semyaza.

"Listen carefully, Grant. Reality is comprised of two parts, that which is seen and that which is unseen. Don't think of them as separate worlds, but as a unified cosmos. The world in which we live is comprised of the natural and the supernatural. Actually, even the term supernatural is misleading. It implies that it's not natural, when in reality it's just as much a part of the natural world as-"

"Excuse me, Professor."

"Yes?"

"You're sounding like a professor."

"Are you saying you don't understand?"

I slumped back on the sofa. "Don't take this the wrong way, but right now I don't need a lecture. What I need are weapons."

"I see."

"Semyaza has all the weapons. I can't stop him. I don't even know where to begin."

"Weapons."

"Yeah. Something I can use to defend myself . . . something that will hurt him, or at least threaten him and make him back off."

"Like a sword."

"Exactly!"

"And maybe a shield."

I was getting through to him. "Yes! Or if you have something more modern, maybe an automatic weapon or nuclear device."

"A spiritual machine gun."

"Now we're talking!" The image of me leveling one of those babies at Semyaza and pulling the trigger played in wide-screen format in my head, complete with surround sound.

The professor was nodding. He understood now. "Here it is . . . ," he said. He leaned forward. I leaned forward, as though we were huddling under a super-secret confidential security bubble. "Truth," he said.

I waited for more. Blinked. "Truth," I repeated.

"An upright heart."

"Professor, maybe you didn't understand me-"

"Faith."

"I need something I can use to-"

"The Word of G.o.d."

He nodded and grinned knowingly as though he'd just handed over an a.r.s.enal of weapons.

"Professor, what I need is-"

"You just don't get it, do you?" he snapped, his voice rising. "After all you've been through and you still don't grasp the concept."

"What I understand is-"

"Your enemy is not human!" the professor shouted. "He is a supernatural being with cosmic power of evil proportions which you cannot begin to comprehend! And for reasons unknown to us, he is stalking you, and he will annihilate you unless you find a way to fight him off!"

"But that's what I'm trying to do!"

"No you're not! You're searching for an enchanted supernatural sword that will intimidate and possibly kill him, a weapon forged by someone else that will swing the balance of power in your favor."

I couldn't argue with that. That's exactly what I wanted.

"Well, I have news for you. It doesn't work that way. You'll have to look elsewhere, Grant. I'm all out of magic swords. I'm sorry you wasted your time coming out here tonight."

He wheeled himself back to give me room to stand.

At the front door I turned back. "You can teach me how to fight him?"

"Yes."

I closed the door and took my seat on the sofa. "I believe you were telling me about the true nature of this universe," I said.

"If you don't understand the nature of the cosmos, you understand nothing," the professor said.

He gestured with a book containing a collection of ancient texts that was old and worn with use. As he spoke he sometimes patted it for emphasis, but rarely did he open it. He gave every indication of having memorized it. "The Bible unashamedly portrays a world that is at once natural and supernatural, a cosmos that is inhabited by both natural and supernatural beings. The spiritual realm is not something that is far away, it is here and now. It is part of the very fabric of the universe.

"Jacob is a wonderful example. The Bible describes how one day he took a journey and on his way stumbled into an encampment of angels. He called the place Mahanaim, which means 'two encampments.' The next day, he got up, and continued on his journey."

"What was the encampment of angels doing on earth?"

"The Bible doesn't say."

"Does it say where the angels went after Jacob left them?"

"No."

"Did they deliver a message of some sort, something useful Jacob recorded that has been pa.s.sed down to us?"

"Nothing."

I was stumped. "So the angels were just vacationing on earth?"

The professor laughed. "We don't know what they were doing. That isn't the point of the story."

"What is the point?"

"That they're here. It's that simple."

"If that's true, why don't more people know about them, or act like they're here?"

The professor sat back in his wheelchair and mulled a moment. "The level of awareness of the supernatural has varied throughout history, by design largely, whatever suits the purposes of Lucifer. G.o.d has always been up-front about its existence. Maybe it would help to think of Lucifer and his bunch as the Mafia . . ."

"That's easy to do," I said.

"A person can drive through downtown New York and never see the Mafia. That doesn't mean they're not there. People can live all their lives in New York and never knowingly encounter the Mafia, though they have probably been affected one way or another by the Mafia's presence. Just because they don't operate out in the open, or people don't talk about them often, doesn't mean the Mafia doesn't exist. But when it is in the Mafia's best interests to make themselves visible, they are more than capable of making their presence known in dramatic and powerful ways. Does that help?"

"So the cosmos consists of natural and spiritual. One is as real as the other. Both are present. Got it. Now what?"

The professor sighed. "The hard part."

"How come there's never an easy part?"

"If I was talking with anyone else at this point, Grant, I would tell you the good news."

"Which is?"

"For a person in Christ, the good news is, 'He who is in you is greater than he who is in the world,' meaning that, for the Christian, G.o.d has placed His Spirit within him to protect and guard him against the devil's evil schemes."

"You're talking about salvation, right? And because I'm Nephilim, I can't be saved."

"Correct. If G.o.d's Spirit was inside of you, Semyaza's demons would not be able to possess you."

"So G.o.d's Spirit is unavailable to me."

"I have nothing that says otherwise."

"Which means?"
