You were only following your master. You don't worry me. I'm prepared to let you live. You and Snakey and the human.

"But the vampire - Larten Crepsley." The vampaneze's red eyes filled with hate. "Him I care about. He should have known better than to get in my way.

Vampires and vampaneze don't mix!" he roared at the top of his voice. "Even the fools of the world know that! It's been agreed upon. We don't interfere with one another's ways. He broke the laws. He must be made to pay."

"He broke no law," I said defiantly. "You're crazy. You were killing people all over the city. You had to be stopped."

"Crazy?" I'd expected Murlough to react furiously to the insult, but he only chuckled. "Is that what he told you? Crazy? Young Murlough isn't crazy! I'm as sane a vampaneze as ever walked. Would I be here if I was crazy? Would I have had sense enough to keep Snakey alive? Do you see me foaming at the mouth? Do you hear me babbling like an idiot? Hmmm?"

I decided to humor him. "Maybe not," I said. "You seem pretty smart now that I think about it."

"Of course I'm smart! Young Murlough's got brains. Can't be crazy if you've got brains, not unless you get rabies. See any rabid animals?"

"No," I said.

"There you are!" he declared triumphantly. "No crazy animals, so no crazy Murlough. You follow, hmmm?"

"I follow," I said quietly.

"Why did he interfere?" Murlough asked. He sounded confused and annoyed.

"I wasn't doing anything to him. I wouldn't have gotten in his way. Why did he have to go and mess things up?"

"This used to be his city," I explained. "He lived here when he was a human.

He felt like it was his duty to protect the people."

Murlough stared at me in complete disbelief. "You mean he did it for them?"

he screeched. "The blood-carriers?" He laughed crazily. "He must be a loony! I thought maybe he wanted them for himself. Or else I killed somebody close to him. I never for a second thought he did it because of... of..."

Murlough started laughing. "That clinches it," he said. "I can't let a lunatic like that run around. No telling what he'll be up to next. Listen to me, Darren Shan.

You look like a smart boy. Let's you and me make a deal. Figure this mess out, hmmm?"

"What kind of a deal?" I asked suspiciously.

"A swap," Murlough said. "I know where Snakey is. You know where the vampire is. One for the other. What do you say?"

"Give up Mr. Crepsley for Evra?" I sneered. "What kind of a deal is that?

Exchange one friend for another? You can't believe I'd -"

"Why not?" Murlough asked. "The snake-boy is innocent, hmmm? Your best friend, he told me. The vampire's the one who took you away from your family, from your home. Evra told me you hated him."

"That was a long time ago," I said.

"Even so," the vampaneze went on, "if you had to choose between the two, who would you pick? If their lives hung in the balance and you could only save one, who would it be?"

I didn't have to consider that very long. "Evra," I said evenly.

"There you are!" Murlough boomed.

"But Mr. Crepsley's life isn't in danger," I said. "You want me to use him to get Evra off the hook." I shook my head sadly. "I don't do that. I won't betray him or lead him into a trap."

"You don't have to," Murlough said. "Just tell me where he is. The name of the hotel and his room number. I'll do the rest. I'll sneak in while he's sleeping, do the business, then take you to get Evra. I give you my word that I'll let both of you go.

Think about it, hmmm? Weigh the options. The vampire or Snakey. Your choice."

Again I shook my head. "No. There's nothing to think about. I'll swap places with Evra myself, if that -"

"I don't care about you!" Murlough screamed. "It's the vampire I want. What would I do with a stupid little half-vampire? Can't drink from you. Nothing to gain by killing you. It's Crepsley or no deal."

"Then it's no deal," I said, sobs rising in my throat as I considered what my words meant for Evra.

Murlough spat at me in disgust. His spit bounced back off the vent. "You're a fool," he snarled. "I thought you were smart, but you're not. So be it. I'll find the vampire myself. Your girlfriend, too. I'll kill them both. Then I'll kill you. Wait and see if I don't."

The vampaneze let go of the wall and dropped into the darkness. "Think of me, Darren Shan," he shouted as he slipped away down a tunnel. "Think of me when Christmas comes around, as you're biting into your turkey and ham. Do you know what I'll be biting into? Do you?" His laugh echoed eerily as he waltzed away down the tunnel.

"Yes," I said softly. I knew exactly what he'd be biting into.

Rising to my feet, I wiped the tears from my face, then took off to wake Mr.

Crepsley and tell him about my meeting with Murlough. After a couple of minutes, I climbed up a fire escape and traveled over the rooftops, just in case the vampaneze had stuck around in hopes of following me back.

CHAPTER EIGHTEEN.

Mr. Crepsley wasn't surprised that Murlough had been watching the hotel - he'd half expected it - but was stunned that I'd gone back to the square.

"What were you thinking?" he snapped.

"You didn't warn me to stay away," I replied. "I did not think I needed to."

He groaned. "What could have possessed you to return?"

I decided it was time to tell him about Debbie. He listened wordlessly as I explained.

"A girlfriend," he said at the end, shaking his head in wonder. "Why did you think I would disapprove? There is no reason you should not befriend a girl. Even full vampires sometimes fall in love with humans. It is complicated, and not to be recommended, but there is nothing wrong with it."

"You're not angry?" I asked.

"Why should I be? Matters of your heart are no concern of mine. You acted properly: you made no promises you could not keep, and you remained aware of the fact that it could only be temporary. All that worries me about your friendship with this girl is how it ties in with the vampaneze."

"You think Murlough will go after her?"

"I doubt it," he said. "I think he will stay clear of the square. Now that we know he has been there, he will expect us to check on the area in the future.

However, you should be careful. Do not go to see her when it is dark. Enter by the back door. Keep away from the windows."

"It's okay for me to keep meeting her?" I asked.

"Yes." He smiled. "I know you think I often spoil the fun, but I would never intentionally make you feel miserable."

I smiled back gratefully. "And Evra?" I asked. "What will happen to him?"

Mr. Crepsley's smile faded. "I am not sure." He thought about it for a couple of minutes. "You truly refused to swap my life for his?" He sounded as if he thought I might be making it up to impress him.

"Honestly," I said.

"But why?"

I shrugged. "We said we'd trust each other, remember?"

Mr. Crepsley turned aside and coughed into his fist. When he faced me again, he looked ashamed of himself. "I have gravely underestimated you, Darren," he said. "I will not do so again. I made a wiser choice than I realized when I chose you to serve as my a.s.sistant. I feel honored to have you by my side."

The compliment made me feel awkward - I wasn't used to the vampire saying nice things - so I grimaced and tried to make nothing out of it.

"What about Evra?" I asked again.

"We shall do what we can to rescue him," Mr. Crepsley said. "It is unfortunate that you refused to swap me for him: had we known Murlough would make the offer, we could have laid a trap. Now that you have shown loyalty toward me, he will not offer again. Our best chance to beat him has slipped away.

"But there is hope yet," he said. "Today is the twenty-third. We know that Evra will not be killed before the twenty-fifth."

"Unless Murlough changes his mind," I said.

"Unlikely. The vampaneze are not renowned for being indecisive. If he said he would not kill Evra until Christmas Day, that is when he will kill him. We have all tonight and tomorrow night to search for his lair."

"But he could be anywhere in the city!" I cried.

"I disagree," Mr. Crepsley said. "He is not in the city - he is under it. Holed up in the tunnels. The drainpipes. The sewers. Hiding from the sun, free to move about as he wishes."

"You can't know that for sure," I said. "He might have only been down there today in order to follow me."

"If he was," Mr. Crepsley said, "we are sunk. But if he has made his base down there, we stand a chance. s.p.a.ce is not so plentiful beneath the ground.

Noises are easier to detect. It will not be easy, but there is hope. Last night, we did not even have that.

"If all else fails," he added, "and we end up empty-handed..." His face hardened. "I will call to our murderous cousin and offer him the deal which you yourself put to him earlier."

"You mean... ?"

"Yes," he said darkly. "If we do not find Evra in time, I will trade my life for his."

There was more s.p.a.ce beneath the ground than Mr. Crepsley had predicted. It was an endless, twisting maze down there. The pipes seemed to go everywhere, like they were thrown down at random. Some were big enough to stand in, others barely large enough to crawl through. Many of them were in use, half full of streams of water and waste. Others were old and dried-up and cracked.

The stench was terrible. One thing was certain: we might happen to hear or glimpse Murlough or Evra, but we'd definitely never be able to sniff them out!

The place was awash with rats and spiders and insects. But I soon discovered that if you ignored them, they generally ignored you back.

"I do not understand why they need so many tunnels," Mr. Crepsley said grimly, after several hours of fruitless searching. We seemed to have walked halfway across the city, but when he stuck his head above ground to check our position, he discovered we'd gone less than three-quarters of a mile.

"I guess different tunnels were made at different times," I said. My dad used to work for a construction company and had explained a little about underground systems to me. "They wear out in places, eventually, and it's usually easier to dig new shafts than go back and patch up the old ones."

"What a waste," Mr. Crepsley grumbled disdainfully. "You could fit a small town into the s.p.a.ce these d.a.m.ned pipes are taking up." He looked around. "There seem to be more holes than concrete," he said. "I am surprised the city has not fallen in upon itself."

After a while, Mr. Crepsley stopped and cursed.

"Do you want to stop?" I asked.

"No," he sighed. "We shall continue. It is better to search than sit back and wait. At least this way we are exerting some sort of control over our destiny."

We used torches in the tunnels. We needed some kind of light: even vampires can't see in total darkness. The beams increased the chances of Murlough's spotting us before we spotted him, but that was a risk we had to take.

"There's no way of hunting him down telepathically, is there?" I asked as we paused for a break. All this crawling and crouching was exhausting. "Couldn't you search for his thoughts?"

The vampire shook his head. "I have no connection with Murlough," he said.

"Tuning into a person's mental signals requires radarlike emissions on both sides."

He held up his two index fingers about a foot apart. "Say this is me." He wiggled his right finger. "This is Mr. Tall." He wiggled the left. "Many years ago, we learned to recognize each other's mental waves. Now, if I want to find Mr. Tall, I emit a radar-like series of waves." He bent his right finger up and down. "When these signals connect with Hibernius, part of his mind automatically signals back, even if his conscious mind remains unaware of it."

"You mean you could find him even if he didn't want to be found?"

Mr. Crepsley nodded. "That is why most people refuse to share their wave ident.i.ty. You should only reveal it to one you truly trust. Less than ten people on Earth can find me that way, or I them." He smiled thinly. "Needless to say, none of those ten is a vampaneze."

I wasn't sure I understood completely about mental waves, but I'd taken in enough information to know Mr. Crepsley couldn't use it to find Evra.

One more hope struck from the list.

But the conversation made me start thinking. I was sure there must be some way of bettering the odds. Mr. Crepsley's plan - to roam the tunnels and pray we fell upon the vampaneze - was weak. Was there nothing else we could do? No way to prepare a trap and lure Murlough into it?

I focused my immediate thoughts on the search - if we stumbled upon the crazy vampaneze, I didn't want to be caught with my head in the clouds - but devoted the rest to serious thinking.

Something the vampaneze had said was poking away at the back of my brain, but I couldn't put my finger on it. I went back over everything he'd said. We'd talked about Evra and Mr. Crepsley and Debbie and making a deal and...

Debbie.

He'd teased me about her, said he was going to kill her and drink from her. At the time I didn't think it was a serious threat, but the more I thought about it, the more I began to wonder how much he really was interested in her.
