The wait was torture, and I started to worry that the guard might have a gun and, being spooked by the sight of Hal, draw it. Somehow twilight had arrived without my noticing its approach, and the impending darkness turned my thoughts gloomy. When I was about ready to come out of hiding and go to Hal's rescue, I heard the door open. I peered around the corner and saw the dog man on all fours, swaying back and forth. The door had closed behind him, though, and the guard had obviously stayed inside. Hal growled and barked, clawing the glass of the door, but to no avail. I realized then that if I was the guard, I might not be too anxious to get too close to this creature either, and I feared I'd miscalculated the situation.

Another minute passed and I was sure the jig was up, but then, in what could only be described as a stroke of genius, the dog man suddenly turned sideways to the door, lifted his leg, and started peeing on it. Before he even finished, he started crawling on all fours toward the other corner of the front of the building. The door swung open, and from my hiding place, I saw the guard emerge, dressed in his blue hat and uniform, holding a billy club.

"Get out of here, you filthy mutt," he yelled. Hal got to his feet and shuffled off around the other side of the building. "Jesus Christ," said the guard. He took two steps, as if to follow, but then stopped. I started to make my move as quietly as possible, walking on tiptoe. The guard was only about eight feet from the entrance, though. I'd have definitely been caught, but just as I was about to open the door, Hal stuck his big dog head around the corner again and let loose a string of vicious barking. The man jumped a little, then lifted his club and gave chase. After that I didn't see what happened. I was inside, moving through the foyer and down a hall to the left, as Stintson had instructed.

SPEAKING OF MUTATION

As I'd hoped, due to the late hour, the halls were deserted. Around the next corner, I found the office Stintson's instructions pointed to. The door was unlocked, and when I opened it, though the lights were already on, the place was empty. I went in and locked the door behind me. Three of the room's walls were lined with wooden filing cabinets and the last held a tall bookcase. There was a chair at a desk with a lamp on it, and opposite that a small couch with one window behind it.

I set to tracing the last names on the cabinets. Stintson's notes had put me in the general area of Agarias's archive, and the specific drawers holding his files were not hard to find. The first drawer I tried was locked though. Pulling out Schell's skeleton key, I went to work. A few seconds later, there came a faint click from within the baffle. The long drawer slid out with one pull on the handle, and I saw it was choked with folders, each crammed with paper.

I didn't know where to start. There were three more drawers similarly stuffed. It's going to take forever, I thought and felt a sense of panic begin to spark to life in my chest.

I took a deep breath and, realizing there was nothing else to do, reached in and pulled out a huge stack of files, about a quarter of what was in the top drawer. Carrying them to the desk, I laid them carefully to one side. I took off my jacket and draped it over the back of the chair, rolled up my sleeves, grabbed the top file, and sat down.

At first, nothing made any sense. There was a lot of scientific jargon concerning blood types, equations, formulas, and testimony concerning individuals who'd been studied. The best I could do was scan as much as I could and keep a lookout for something that rang a bell or that made things clearer.

Somewhere well into the second half hour, I started skipping files, simply glancing down whole sheets without actually reading, jumping around from file to file until the stack beside me on the desk became two stacks and then three and then just a mess of folders. Just when I thought that perhaps my trip to the ERO, calling Hal in from Brooklyn, the whole elaborate con was going to go to waste, I finally picked up on the thread of something that seemed familiar. I recalled Stintson mentioning Agarias's experiment with twins, and from the look of the text I was then scanning, I had blundered my way into the middle of that research.

I did some backtracking, found the origin of the research in question, and then moved forward. Even though my eyes were weary by then, and my back hurt from leaning over the desk, I was infused with a new energy and clarity of vision. And then I caught sight of the name Shaw. I read on at a rapid rate as it became clear to me that I had before me certain pieces of the puzzle.

It was precisely when I uncovered an interesting fact concerning Morgan that I heard the sound of footsteps outside the door. A key slid into the lock from outside. There was no time for me to even get out of my chair. The door opened a sliver, tentatively at first, and then swung all the way in. Standing in the entrance, smiling, was Agarias. I stood up, thinking there was going to be trouble.

He tilted his head downward to look at me over the rims of his round glasses, and said, "If it isn't the spiritual savant of the subcontinent. Ondoo, is it?"

"What have you done with Schell?" I asked.

"He's in my keeping. Safe, for now."

Seeing he was alone, I started to move around the desk. All I wanted to do was punch him.

"Please sit down," he said.

When I kept advancing, he added, "If you'd like to see Mr. Schell again, I'd sit down."

I stopped in my tracks, unclenched my fist, and backed off.

"Sit down and I'll tell you anything you'd like to know, really. I've nothing to hide. Let me warn you, though, if you can't control yourself, I've got a gun, and I wouldn't mind shooting you." He patted the side pocket of his jacket as he took a seat on the couch.

"How did you know I was here?" I asked.

"After you and Schell went to see Stintson, I figured he would lead you here."

"Stintson?" I said in a weak attempt to cover the truth.

"Yes, poor Stintson. It seems he'll be all over the front page tomorrow. A robbery, I'm afraid."

I closed my eyes momentarily at the knowledge that we had been responsible for the man's death. "Okay," I finally said. "All I want is Schell. Tell me what I need to do to get him back, and we'll forget all about you."

"Simple," said Agarias, "I want Morgan Shaw. An even exchange."

"Why?"

"She's critical to my work," he said.

"She's legally your daughter, isn't she?" I said.

Agaias nodded. "Adopted. She and her brother. The twins of twins born of twins."

"What is it about twins?"

"Good question," he said, shaking his finger at me. "We know that incest begets birth anomalies, correct?"

I nodded.

"This is why it's illegal to marry, say, your sister, or even your first cousin. But I discovered this family out in the woods, where the laws of civilization were largely ignored. I waited until the children came of age and then, shall we say, persuaded them to couple. Imagine now, if incest between first cousins, brothers and sisters, causes mutations, just think about what the union of twins might produce. You see? When I first stumbled upon these degenerates, I noticed something in the early bloodwork, some anomaly. Over the two successive generations it has become more pronounced."

"Speaking of mutations," I said, "what exactly is that creature you sent to murder Parks and visit us at Schell's?"

"That's my boy, Merlin," said Agarias, smiling. "He's quite a physical specimen, isn't he?"

"He's deformed," I said.

"Now, now," he said. "Merlin is a very special individual. Granted, he's not the most handsome fellow. But take, for instance, his skin. He's not albino. Albino is the lack of pigmentation. His pigment is white. The other thing about him, and this is most important, he's got a blood type like none other."
